On s’intéresse dans cette thèse à l’étude des fonctions thêta intervenant dans la preuve de l’équation fonctionnelle des fonctions L de Dirichlet. En particulier, on adapte certains résultats obtenus dans le cadre des fonctions L au cas des fonctions thêta. S. Chowla a conjecturé que les fonctions L de Dirichlet associées à des caractères χ primitifs ne doivent pas s’annuler au point central de leur équation fonctionnelle. De façon analogue, il est conjecturé que les fonctions thêta ne s'annulent pas au point 1. Dans le but de prouver cette conjecture pour beaucoup de caractères, on étudie les moments de fonctions thêta dans plusieurs familles. On se focalise sur deux familles importantes. La première considérée est l’ensemble des caractères de Dirichlet modulo p où p est un nombre premier. On prouve des formules asymptotiques pour les moments d'ordre 2 et 4 en se ramenant à des problèmes de nature diophantienne. La seconde famille considérée est celle des caractères primitifs et quadratiques associés à des discriminants fondamentaux d inférieurs à une certaine borne fixée. On donne une formule asymptotique pour le premier moment et une majoration pour le moment d'ordre 2 en utilisant des techniques de transformée de Mellin ainsi que des estimations sur les sommes de caractères. Dans les deux cas, on en déduit des résultats de non-annulation des fonctions thêta. On propose également un algorithme qui, pour beaucoup de caractères, se révèle en pratique efficace pour prouver la non-annulation sur l'axe réel positif des fonctions thêta ce qui entraîne la non-annulation sur le même axe des fonctions L associées. / In this thesis, we focus on the study of theta functions involved in the proof of the functional equation of Dirichlet L- functions. In particular, we adapt some results obtained for L-functions to the case of theta functions. S. Chowla conjectured that Dirichlet L- functions associated to primitive characters χ don’t vanish at the central point of their functional equation. In a similar way to Chowla’s conjecture, it is conjectured that theta functions don't vanish at the central point of their functional equation for each primitive character. With the aim of proving this conjecture for a lot of characters, we study moments of theta functions in various families. We concentrate on two important families. The first one which we consider is the family of all Dirichlet characters modulo p where p is a prime number. In this case, we prove asymptotic formulae for the second and fourth moment of theta functions using diophantine techniques. The second family which we consider is the set of primitive quadratic characters associated to a fundamental discriminant less than a fixed bound. We give an asymptotic formula for the first moment and an upper bound for the second moment using techniques of Mellin transforms and estimation of character sums. In both cases, we deduce some results of non-vanishing. We also give an algorithm which, in practice, works well for a lot of characters to prove the non-vanishing of theta functions on the positive real axis. In this case, this implies in particular that the associated L-functions don’t vanish on the same axis.

The Institution of the res iudicata is treated in the Brazilian Law by the Constitutional Text, by the Brazilian Civil Process Code, besides the Law of the Introduction to the Brazilian Civil Code and sparse legislation. Due to the multiplicity of Law subjects taking care of the Institution, for one part of the doctrine, it would not have constitutional protection and it could be modified and even abolished under infraconstitutional norms. Under that premise, it was built the doctrine known as relativism of the judged thing , that links the effects of the resiudicata thing to its normative fundament of validity or the justice of decisum. Once the chosen subject has its very own characteristics of almost exclusive development in the national doctrine it was privileged the doctrine exam and national jurisprudence, not failing to remember, nevertheless, the contributions of the foreign doctrine, when, effectively, they could support the analyzes of the approached issues in this Essay. The text presents the origins of the res iudicata and classifies the essential process elements for the understanding of the Institution as a process-juridical category. It examines the principle of juridical reliability, its historical evolution and its interpretation in the current law, as well as, the nature of the judged thing as a normative category, to the Institution position in the Brazilian Constitutional text. It also mentions, the juridical nature of the formed sentences in rejoinder to the present Federal Constitution and the effects of the doctrinaire positioning that states the no existence of the unconstitutional res iudicata. Yet, it proceeds, to the study of the new writing of the articles 475-L § 1st and 741, single clause, of the Brazilian Process Civil Code, consolidated by the Law number 11.232/2005, that partially accepted, the above indicated theory. At last, it dedicates considerations on representative judicial decisions of practical difficulties that the application of the Institution has had in the brazilian jurisprudence / Esta Dissertação tem por objetivo conceituar, analisar e interpretar a chamada coisa julgada inconstitucional no campo doutrinário, no seu tratamento normativo e na aplicação prática da jurisprudência dos tribunais nacionais, no âmbito do direito público. O Instituto da coisa julgada é tratado no direito brasileiro pelo Texto Constitucional, pelo Código de Processo Civil Brasileiro e pela Lei de Introdução ao Código Civil Brasileiro, além de legislação esparsa. Ante a multiplicidade de esferas normativas cuidando do Instituto, para uma parte da doutrina, ele não teria proteção constitucional e poderia ser modificado e até abolido por normas infraconstitucionais. Por tal premissa, foi construída doutrina conhecida como relativização da coisa julgada , que vincula os efeitos da coisa julgada ao seu fundamento normativo de validade ou à justiça do decisum. Face as características muito próprias do tema escolhido, - de desenvolvimento quase que exclusivo na doutrina nacional -, privilegiou-se o exame da doutrina e jurisprudência nacionais, sem olvidar, no entanto, as contribuições da doutrina estrangeira, quando, efetivamente, puderam auxiliar na análise das questões abordadas nesta Dissertação. O texto apresenta as origens da coisa julgada e conceitua os elementos processuais essenciais para a compreensão do Instituto como categoria jurídico-processual. Examina o princípio da segurança jurídica, sua evolução histórica e sua interpretação no direito atual, bem como a natureza da coisa julgada como categoria normativa, face a posição que o Instituto ocupa no texto constitucional brasileiro. Aborda, também, a natureza jurídica das sentenças formadas em contrariedade à Constituição Federal vigente e os efeitos do posicionamento doutrinário que apregoa a inexistência da coisa julgada inconstitucional. Procede, ainda, ao estudo da nova redação dos arts. 475-L § 1º e 741, parágrafo único, do Código de Processo Civil brasileiro, cristalizada pela Lei nº 11.232/2005, que acolheu, ao menos em parte, a teoria acima indicada. Por fim, dedica considerações sobre decisões judiciais representativas das dificuldades práticas que a aplicação do Instituto tem gerado na jurisprudência brasileira

It deals with the exceptional hypothesis in which the objective the deconstitution of a sentence wich become already finished, with a deadline for bringing the rescission has passed, due to the advent of a new evidence, the DNA exame, which can demonstrate that the sentence undercover the mantle of res judicata may be flawed. The lawyers, facing this situation, often joining with an autonomous action aimed at reform of the decision, because there is no other remedy applicable, for the duration of action for rescission have been exhausted. In these legal actions often requires the examination of DNA, now joins the other application the report of the examination, because it has already been done (and demonstrates that the sentence, covered up the mantle of res judicata, is wrong) .Given this situation, extraordinary and unusual, there was a great concern in doctrine, but also in the courts, because what is the best solution: to relativize the res judicata or keep it? In answering this question the lawyers always end up saying the conflict between security and justice. The relativistic point that justice must prevail, since the non-relativistic point that should place the principle of legal certainty. The study includes some innovative features, such as the detailed study of all cases decided by the Superior Court of Justice (STJ), which is made a detailed percentage of cases that were for and against the theory of relaxation of res judicata, which enables understanding of how they developed the theory of relativity of res judicata before the Supreme Court. Another innovation is the attempt to show the conflict between security and justice on another aspect, something already done by other scholars, in works on other subjects (such as the legal philosophy), but not done yet in the case of relativization of res judicata in actions of paternity / O presente trabalho visa discutir sobre a relativização da coisa julgada, nas ações de investigação de paternidade. Trata de hipótese excepcional na qual se objetiva a desconstituição de uma sentença já transitada em julgado, com prazo para interposição da rescisória transcorrido, em virtude do advento de um novo meio de prova, o exame de DNA, o qual pode demonstrar que a sentença acobertada pelo manto da coisa julgada material pode estar equivocada. Os advogados, diante de tal situação, costumam ingressar com uma ação autônoma objetivando a reforma da decisão, porque não há outro remédio aplicável, pois o prazo da ação rescisória já foi esgotado. Em aludidas ações muitas vezes se requer a realização do exame de DNA, em outras já se junta à petição inicial o laudo do exame, pois o mesmo já foi realizado (e demonstra que a sentença, acobertada pelo manto da coisa julgada, está equivocada). Diante desta situação, extraordinária e atípica, surgiu uma grande inquietação na doutrina, como também nos Tribunais, pois qual será a melhor solução: relativizar a coisa julgada ou mantê-la? Ao responder esta indagação os juristas acabam sempre alegando o conflito existente entre segurança e justiça. Os relativistas apontam que a justiça deve prevalecer, já os nãorelativistas apontam que deve prevalecer o princípio da segurança jurídica. O presente estudo traz alguns aspectos inovadores, como o estudo detalhado de todos os casos decididos pelo Superior Tribunal de Justiça (STJ), onde é feito um detalhamento percentual dos casos que foram favoráveis e contrários à teoria da flexibilização da coisa julgada, o que possibilita o entendimento de como se desenvolveu a teoria da relativização da coisa julgada perante o STJ. Outra inovação é a tentativa de mostrar o conflito entre segurança e justiça sobre outro aspecto, algo já realizado por outros doutrinadores, em obras sobre outras matérias (a exemplo da filosofia jurídica), mas não realizado ainda em se tratando de relativização da coisa julgada nas ações de investigação de paternidade

The evaluation was preceded by literature review in public databases and academic literature on the economic, social, cultural, environmental situation, policy and solid waste management in the municipality. Thus, aiming to add value to research and enhancing the systemic view, were introduced information on the understanding of 44 social representatives, residents and collectors of recyclable materials on municipal solid waste management, through a questionnaire. In addition, field observations were carried out in 22 of the 44 districts of the municipal headquarters and in eight districts. The array of indicators used is composed of six dimensions of sustainability, key questions and 42 indicators of which five are indicators of the political dimension, four technological, four in the economic / financial dimension, thirteen environmental / ecological dimension, ten dimension of knowledge (Environmental Education and Social Mobilization) and six in the dimension of social inclusion. The matrix also presents three descriptors for each indicator totaling 126, with space for setting of bookmark note that varies from 0 to 5. After application of the matrix, the level of sustainability was 4.1, corresponding to a low- sustainability, and the financial and social inclusion the most unsustainable dimensions. The results found convenes public managers for emergency decision making, such as the development of solid waste management plan, as required by National Policy on Solid Waste and draws attention to the importance of popular participation in the Municipal Solid Waste Management.

L’autorité de la chose jugée, expression de l’exigence de stabilité des décisions juridictionnelles et de la capacité de l’Etat souverain à exercer son pouvoir juridictionnel en tranchant définitivement l’affaire lui étant soumise, est fortement liée à l’enchainement processuel dont elle constitue l’aboutissement naturel. Ces dernières années, en raison de l’influence du droit supranational, la chose jugée subit également un processus d’érosion de son caractère irréfragable. En particulier, alors que le conflit entre chose jugée et décisions de la Cour de justice de l’UE apparait comme « pathologique », les spécificités du système conventionnel de protection des droits de l’homme provoquent un conflit quasi « physiologique » avec la chose jugée de droit interne. La nature particulière de ce dernier type de conflit s’explique non seulement en raison du principe de subsidiarité et de l’épuisement des voies de recours internes qui caractérisent la saisine de la Cour EDH, mais aussi du fait de la nécessité d’une « restitution in integrum » du requérant victime d’une violation conventionnelle qui impose une obligation de réouverture de la procédure interne, en exécution de l’article 46 Conv. EDH. La thèse analyse, sous l’angle comparé du droit italien et français, les notions qui sous-tendent ce conflit, à savoir la valeur de la res iudicata et l’incidence des systèmes européens de protection des droits fondamentaux sur l’ordre processuel interne pour ensuite se pencher sur les modalités concrètes par lesquelles les deux ordres juridiques ont permis le dépassement de l’autorité de la chose jugée pour garantir l’exécution des arrêts de la Cour EDH. Dans le cadre ainsi tracé, la récente entrée en vigueur du Protocole n. 16 à la Conv. EDH, introduisant un mécanisme consultatif devant la Cour EDH, ainsi que les perspectives offertes par le Protocole n. 15 à la Conv. EDH et par la possible adhésion de l’Union au système conventionnel, viennent recentrer le rôle reconnu à la Cour EDH en tant que juridiction régulatrice d’un système européen de protection des droits fondamentaux, et favorisent le dépassement du conflit entre la chose jugée et les décisions européennes en faveur du paradigme du "dialogue" entre les juges. / The effect of res judicata (also known as “a thing adjudged), an expression of the stability requirement of the jurisdictional decisions and the sovereign state’s capacity to exercise its jurisdictional power by making the final judgement on the matter, is a concept strongly connected with the criminal process which constitutes its natural result. In the last few years, as a result of solicitations of supranational origin whose domestic law is subject, res judicata also undergoes a process of erosion of its irrefutable nature. In particular, while the conflict between res judicata and decisions of the Court of Justice of European Union appears to be “pathological”, the specificities of the conventional system of human right protection provoke a virtually “physiological” conflict with the the doctrine of res judicata in domestic law. This is done considering the principle of subsidiarity and the exhaustion of domestic remedies which characterize the appeal to the European Court of Human Rights jointly with the fact that the requirement of the effective "restitutio in integrum" of the applicant victim of a recognized breach of his rights imposes an obligation to reopen the domestic proceedings, according to article 46 ECHR. The thesis analyses under the angle of Italian and French law, the concepts underlying the conflict, especially the value of res judicata and the impact of European systems of protection of fundamental rights on the internal criminal process, secondly, to examine the concrete ways in which the two legal orders have allowed the effect of res judicata to be exceeded in order to guarantee the execution of ECHR judgments. In this context, the recent entry into force of the Protocol n. 16 at EDH, introducing a consultative mechanism before the ECHR, as well as the prospects outlined by the Protocol n. 15 at ECHR and by the possible accession of the European Union to the conventional system, refocus the recognized role of the ECHR as a regulatory jurisdiction of the European protection system for fundamental rights, and promote the overcoming of the conflict between res judicata and European decisions in favor of the "dialogue" between judges.

Inom ramen för Förenta nationernas internationella handelsorgan United Nations Commission on International Trade Law (UNCITRAL) har en konvention om internationella medlingsförfaranden (Singaporekonventionen) antagits. Denna syftar till att harmonisera den internationella handelsrätten, särskilt avseende alternativa tvistelösningsmetoder. I Sverige finns sedan 2011 lagen om medling i vissa privaträttsliga tvister, som reglerar hela medlingsprocessen, från hur förfarandet ska gå tillväga till hur en eventuell överenskommelse kan erhålla status som en exekutionstitel. Denna status nås, enligt svensk rätt, genom att en domstol meddelar en verkställbarhetsförklaring. Vid en prövning av en ansökan om verkställbarhetsförklaring från parterna, ska en domstol meddela förklaringen om innehållet i avtalet är sådant att det kan verkställas i Sverige. Avseende dessa så kallade vägransgrunder, går Singaporekonventionen längre och tillåter att en domstol vägrar att förklara en överenskommelse verkställbar om avtalet på något sätt är ogiltigt. Följaktligen medför Singaporekonventionen en mer omfattande prövning för domstolen, i och med att fler faktorer behöver beaktas innan en verkställbarhetsförklaring meddelas. En annan konsekvens är å andra sidan att risken för materiellt oriktiga verkställbarhetsförklaringar undviks i högre utsträckning.   Konventionen aktualiserar dessutom andra frågeställningar, nämligen hur en domstol ska hantera en invändning om att en medlingsöverenskommelse redan har avgjort saken som är föremål för talan i ett ordinärt, dispositivt, tvistemål. Överenskommelsen kan inte i sig utgöra en grund för att rättegångshinder föreligger, i och med att bestämmelsen om res judicata tar sikte på situationer där saken har varit föremål för en materiell prövning, vilket en ansökan om verkställbarhetsförklaring inte kan anses ha varit. Däremot medför en medlingsöverenskommelse en bevisverkan, i form av att parterna har avsagt sig att åberopa de eventuellt tillämpliga materiella bestämmelserna till förmån för det avtal som medlingsöverenskommelsen är ett uttryck för.

Sustainable cities is an area that has grown in size over the last couple of years. The SESAC (Sustainable Energy Systems in Advanced Cities) is a EU-project looking at the potential to increase the share of Renewable Energy Sources (RES) and promote energy efficiency measures in different EU cities. This master thesis is a part of that project. Specifically, the thesis examines the cities of Grenoble, Delft and Växjö and looks at what measures regarding RES and energy efficiency have been taken historically, both under the SESAC project and otherwise, and assesses the possibility of further measures in the cities. The main RES evaluated are wind power (large scale and urban), solar (PV and thermal) and waste treatment (waste incineration and biogas production). The feasibility of these renewable technologies is evaluated both physically, technically and economically for each city. Further, the historical and current hinders and promoters in the form of different support schemes and other economic and institutional schemes are summarized for each country and city and the effects of which included in the feasibility calculations. Also, current CO2 emissions of Grenoble, Delft and Växjö are stated and the impact of implementing the measures examined is calculated. A comparison between the three cities is also made and suggestions are made to what they can learn from each other and what synergies there are.    Results show that the technical potential for RES is sizeable in the cities, as seen in Table 1. Important to note are the differences between the cities. Besides from their differences in population size, ranging from 83 000 (Växjö) and 96 000 (Delft) to 400 000 (Grenoble), available land area as well as climate are very different in the cities, therefore affecting the potential for the RES technologies.   RES potential [GWh] Grenoble Delft Växjö Wind 458 1,2 (Urban only) 297-2000 Solar PV 375 150 0,06-0,3 Waste treatment 41 11 10 Table 1. Technical potential of RES in Grenoble, Delft and Växjö Looking at the economic potential, however, the picture is not as optimistic. The only economically feasible investments of the options in Table 1 are investing in solar PV in Grenoble and Delft (IRR of 0-10%) and wind in Växjö (IRR of 4%). All other investments have negative NPV:s and IRR:s, meaning that either the cost of the technologies must be reduced or more favorable support scheme be introduced in order to make the them profitable.

Studien bygger på vetenskaplig forskning om den pågående klimatkrisen och dess allvarliga konsekvenser. Den har sin grund i de mål som fastställts av FN:s klimatkonvention i Parisavtalet. Dessa mål syftar till att stipulera förändringsområden inom sektorer som i dagens läge har en betydande global miljöpåverkan. Frågeställningen i denna studie lyder “På vilket sätt påverkar design av gränssnitt i res- och transporttjänster användares klimatmedvetenhet i beslutsfattande kring resor?” Denna studie genomför en kartläggning genom en enkätstudie och intervjuer för att utforska hur design av gränssnitt i res- och transporttjänster påverkar användares klimatmedvetenhet i beslutsfattande kring resor. Studien utforskar de aktuella problemen med gränssnittsdesign men även hur urvalsgruppen tänker kring hållbart resande. Resultaten av denna studie syftar till att ge information om potentialen till att leda användare på rätt väg genom hållbar design av gränssnitt i res- och transporttjänster. Detta görs genom att presentera resultatet från enkätstudien och intervjuerna som diskuterar om hur hållbar design bör implementeras. Studien lyfter även fram på vilket sätt hållbar design kan introducera potentiella fördelar såsom mer information vilket kan leda till mer hållbara val. Studien utforskar även de hinder som kan stå i vägen för implementering av hållbart resande. Studiens resultat indikerar att den befintliga designen av gränssnitt i rese- och transporttjänster har påverkat respondenterna och även hindrat dem från att fatta hållbara beslut vid planering av resor. Designen av gränssnittet har haft en negativ effekt på användarnas förmåga att välja alternativ som är mer miljövänliga och hållbara. Detta betonar behovet av att förbättra designen av gränssnitten för att ge användarna enklare tillgång till och stödja deras förmåga att göra hållbara val vid resplanering. / This study is based on scientific research concerning the ongoing climate crisis and its consequences. The basis of this study lies in the goals established by the United Nations Framework Convention on Climate Change (UNFCCC) in the Paris Agreement. These goals stipulate areas of change within sectors that currently have a significant global environmental impact. The research question in this study reads "In what way does the design of interfaces in travel and transport services influence users' climate awareness in decision-making around travel?" This study conducts a survey using a questionnaire as well as interviews to explore how the design of interfaces in travel and transportation services affects users' climate awareness in travel decision-making. The study explores the current problems with interface design but also how the sample group thinks about sustainable travel. The results of this study aim to provide information on the potential to guide users on the right path through sustainable interface design in travel and transportation services. This is done by presenting the results from the survey study and the interviews that discuss how sustainable design should be implemented. The study also highlights how sustainable design can introduce potential benefits such as more information which can lead to more sustainable choices. The study also explores the obstacles that may stand in the way of implementing sustainable travel. The results of the study indicates that the existing design of interfaces in travel and transportation services has influenced the respondents and also prevented them from making sustainable decisions when planning their trips. The design of the interface has had a negative effect on users' ability to choose options that are more environmentally friendly and sustainable. This emphasizes the need to improve the design of the interfaces to provide users with easier access and support their ability to make sustainable travel planning choices.

One of the challenging issues with the Microgrid is that the bidirectional power flow providedby the distributed generator (DG) which modify the fault current level. Furthermore, theinverter based-renewable energy source (IB-RES) limits the total fault current contributionto the grid due to its thermal capability. Since Microgrid should be able to operate in gridconnectedand islanded mode, protection strategies are needed to solve this challenging issue.By only having IB-RES and battery storage system, the fault condition and normaloperation cannot be distinguished. Apart from fault clearing issue, there is a consideration tostudy the fault isolation in the Microgrid under the limited fault current provided by IB-RES.To have fault isolation capability, the intelligent electrical device (IED) is needed. The firststep is to find a method that can detect a fault under the fault level modification constraint.This thesis presents a zero and negative sequence current protection to detect a fault.However, to make it selective, this protection will be applied directionally. It is common thatthe distribution grid has unbalanced load operation, thus providing zero and negativesequence component in the grid. To apply the directional zero and negative sequence currentprotection, the unbalanced load flow is simulated to distinguish the fault and normaloperation under unbalanced load condition.Safety and regulation are discussed briefly in this thesis. It is important that each of theIB-RES has fault ride-through (FRT) capability that follows a regulation. However, thisregulation is expected to have a coordination with the proposed protection in the Microgridso the reliability, selectivity, and sensitivity can be achieved in grid-connected and islandedmode. This thesis shows the coordination between fuses, IED, and inverter FRT capability.After providing a protection strategy, the adaptability of the proposed protection isassessed regarding of Microgrid expansion. The result shows that by applying the schemeand following the grading margin requirement that is presented in this thesis, the Microgridexpansion will not disrupt the proposed protection coordination. Since it is known that thedistribution grid is expanding its load capacity and microgeneration in continuous basis, it isconvenient that the proposed protection in the IED is expected to be adaptable, means that ithas a fixed IED setting when the grid is expanded. The analysis is performed by electrical transient analysis program (ETAP) and MatlabSimulink. The short circuit analysis, sequence-of-operation, and unbalanced load flow aresimulated by ETAP, while the protection stability is simulated by Matlab Simulink. / Ett problem som finns med microgrid är att de distribuerade produktionsgeneratorerna harett dubbelriktat effektflöde som modifierar felströmmen. Dessutom, inverterbaseradeförnyelsebara energikällor (IB-RES) begränsar det totala felströmsbidraget på grund av desstermiska kapacitet. Eftersom microgrids ska vara operativ vid både anslutning till externt nätsamt önätsdrift behövs skyddsstrategier för att kunna hantera fel, speciellt vid önätsdrift.Om endast IB-RES och batterilager används kan feldrift och normal drift inte särskiljas.Bortsätt från felhantering är det viktigt att studera felbortkoppling för microgrid underbegränsad felström som fås av IB-RES. För att kunna åstadkomma felbortkoppling behöveren IED (från engelskans Intelligent Electronic Device). Det första steget är att finna en metodför att kunna detektera fel under fel nivå modifiering. Denna avhandling tittar på att användanoll- och minusföljds ström sekvensskydd för att detektera fel. För att göra skyddet selektivtkommer det att titta på riktningen av effektflödet. I distributionsnät är det vanligt att haobalanserade laster vilket medför noll- och negativa sekvenskomponenter i nätet. För atttillämpa riktningsskydd för noll och negativ sekvens ström simuleras ett obalanserateffektflöde för att särskilja på feldrift och normal drift vid obalanserad last.Säkerhet och förordningar diskuteras kortfattat i denna avhandling. Det är viktigt att varjeIB-RES har en feltålighet som följer vissa förordningar. Denna förordning förväntassamordna det föreslagna skyddet i micronåt så att pålitlighet, selektivitet och känslighet kanåstadkommas vid nätanslutning och önätsdrift. Denna avhandling visar samordningen mellansäkringar, IED och feltåligheten för växelomriktare.Anpassningsförmågan för det föreslagna skyddet bedöms med avseende på expansion avmicrogrid. Resultatet visar att en expansion av ett microgrid inte kommer att störa denföreslagna samordningen om skyddsmetoden och tidsfördröjningskravet som presenteras idenna avhandling följs. Eftersom det är känt att distributionsnätet kommer att fortsätta ökasin lastkapacitet och mikrogenerering, är det lämpligt att skyddet förväntas varaanpassningsbart vilket innebär att det har en fast IED inställning när nätet expanderas.Analysen genomförs med mjukvarorna electrical transient analysis program (ETAP) ochMatlab Simulink. Kortslutningsanalysen, arbetssekvensen och obalanserad lastflödesimuleras av ETAP, medan skyddsstabiliteten simuleras av Matlab Simulink.
