Estimação de estado em sistemas elétricos de potência: composição de erros de medidas / State estimation in power systems: measurement error composition

Piereti, Saulo Augusto Ribeiro 10 August 2011 (has links)
Bretas et al. (2009) prova matematicamente, e através da interpretação geométrica, que o erro de medida se divide em componentes detectáveis e não-detectáveis. Demonstra ainda que as metodologias até então utilizadas, para o processamento de Erros Grosseiros (EGs), consideram apenas a componente detectável do erro. Assim, dependendo da amplitude das componentes do erro, essas metodologias podem falhar. Face ao exposto, neste trabalho é proposto uma nova metodologia para processar as medidas portadoras de EGs. Essa proposição será obtida decompondo o erro da medida em duas componentes: a primeira, é ortogonal ao espaço da imagem da matriz jacobiana cuja amplitude é igual ao resíduo da medida, a outra, pertence ao espaço da imagem da matriz jacobiana e que, por conseguinte, não contribui para o resíduo da medida. A relação entre a norma dessas componentes, aqui denominado Índice de Inovação (II), prevê uma nova informação, isto é, informação não contida nas outras medidas. Usando o II, calcula-se um valor limiar (TV) para cada medida, esse limiar será utilizado para inferir se a medida é ou não suspeita de possuir EG. Em seguida, com as medidas suspeitas em mãos, desenvolve-se um índice de filtragem (FI) que será utilizado para identificar qual daquelas medidas tem maior probabilidade de possuir EG. Os sistemas de 14 e 30 barras do IEEE, e o sistema sul reduzido do Brasil de 45 barras, serão utilizados para mostrar a eficiência da metodologia proposta. Os testes realizados com os sistemas acima são: i) O teste de nível de detecção de EG, que consisti em encontrar o valor mínimo de EG que seja detectado usando o TV da medida; ii) O teste onde é adicionado EG de 10 desvios padrões em cada medida, uma por vez, nesse teste o FI da medida é usado para identificar qual medida possui o erro, em seguida à medida com erro é corrigida através do erro normalizado composto (ENC); iii) O teste de EG simples. / Bretas et al. (2009) has proved, using geometric background, that the measurement error can be decomposed into two components the detectable and the undetectable component respectively. Bretas has also demonstrated that the current methodologies used for processing of gross errors (GE), consider only the detectable component of the error. Thus, depending on the magnitude of the undetectable error components, such methods may fail. Given the above explanation, in this work a new methodology for processing the measurements with GE is proposed. This proposition is obtained by decomposing each measurement error into two components: the first, orthogonal to the Jacobian range space, whose magnitude is equal to the measurement residual and the other contained in that space, which does not contribute to the measurement residual. The ratio between the norms of those components was proposed as the measurement Innovation Index (II) which provides the new information a measurement contains regarding the other measurements. Using the II, a threshold value (TV) for each measurement is computed so that one can declare a measurement suspicious of having a GE. Then a filtering index (FI) is proposed to filter up, from the suspicious measurements, the one that has more chances of containing a GE. The IEEE-14 bus system, IEEE-30 bus system, and reduced 45-bus power system of south of Brazil, will be used to demonstrate the accuracy and efficiency of the proposed methodology. Tests conducted with the above systems were: i) The level test for GE detection, which consists in finding the minimum GE value in order it can be detected using the measurement TV; ii) The test where GE of 10 standard deviations is added to each measurement, once at a time, and using the measurement FI to identify which measurement has the error ant the using the composed measurement error (CNE) to correct measurement value; iii) The GE simple test.

Inovační management ve vybraném MSP / Innovation management in chosen company

LACINOVÁ, Kristýna January 2017 (has links)
The master thesis is dedicated to the use of innovation management in small and medium-sized enterprises. The theoretical part contains explanation of terms related to the innovation management, inventions, innovations, classification of innovations, measurement and effectivity of innovations. According to the opinions of many authors, the company that does not innovate is doomed to fail. That is why the often-used motto of companies is "Innovate or die". The chosen company which does not want to be named is described in the practical part. The enterprise is an important printing company with more than 20 years-long history. The aim of the master thesis is to describe and evaluated the realized innovation of the company. The output of the thesis contains plan of the processing map of the innovation, evaluation of the innovation by innovation index KLII and creation of the innovation benefits pyramid. The results of the thesis may contribute to lower costs of realization of future innovations, strengthening of the vision of the company and an increase of competitiveness.

Évaluation de la capacité à innover : une approche par auto évaluation et suivi supporté par des analyses multicritères dynamiques / Evaluation of Innovation capabilities : A self assessment approach and monitoring supported by multi-criteria dynamic analysis

Galvez Manriquez, Daniel 09 February 2015 (has links)
L’un des challenges les plus importants des pays développés ou émergents est de soutenir l’innovation dans les PME. Mais la question centrale ici, est de savoir si l’innovation dépend exclusivement de la disponibilité des ressources. La capacité à innover ne dispose pas d'un cadre de référence pour son évaluation, en raison principalement de sa complexité et sa nature abstraite. Sans les indicateurs appropriés, il est impossible d'établir les objectifs et de déterminer les efforts et les ressources nécessaires pour améliorer la capacité d'innovation. Le laboratoire ERPI a développé une approche d’évaluation de cette capacité privilégiant les pratiques internes qui favorisent l’innovation dans les entreprises (IIP, Indice d’Innovation Potentielle) basée sur des méthodes d’analyse multicritère. Mais une fois obtenu un résultat, quels sont les points sur lesquels une entreprise peut jouer afin d’améliorer son système d'innovation ? Dans cette thèse, nous proposons un modèle d'optimisation qui réplique la procédure d'évaluation de la capacité à innover utilisée par l'IIP et qui nous permettra de générer un plan d'action pour améliorer la capacité à innover des PME. Le modèle considère différents facteurs (la situation particulière de l'entreprise, les efforts économiques associés à la stratégie proposée, etc.) afin de générer le plan d'action le plus approprié aux besoins de chaque PME. Ainsi, trois stratégies potentielles sont proposées : améliorer le classement actuel avec un minimum d'effort, maximiser les économies de ressources, maximiser l’IIP avec un budget défini. Des scénarii sont simulés afin de tester les résultats de la mise en œuvre des différentes stratégies / One of the most important challenges in the current industrial policy of developed and emerging countries is to support innovation in SMEs, issue which has been approach as a problem only dependent on the availability of resources. Innovation capability does not have an appropriate framework of evaluation, mainly because of its complexity and abstract nature. Without proper indicators, it is not possible to establish objectives and identify the efforts and resources necessary for its improvement. In response to this, the ERPI laboratory has developed an evaluation approach of innovation capability, taking into account internal practices to promote innovation. A field of knowledge has been developed in this direction allowing for the proposal of a novel metrology, the Potential Innovation index (PII), based on multi-criteria analysis methods for studying the dynamics within companies. In this thesis, we propose an optimization model that replicates the evaluation procedure of innovation capability to generate an action plan, i.e., the model returns concrete points in which companies can work to improve its innovation system. The model considers factors such as the particular situation of the company, the economic efforts associated with the proposed strategy, the goals of the entrepreneur, etc. Three optimization strategies are proposed: access to a higher category with a minimum of effort, maximize resource efficiency and maximize innovation performance with a defined budget. Scenarios are simulated to test the results of the implementation of the different strategies

Cashless society: Is there a relationship between innovation and cash circulation in economy? / Kontantlöst samhälle: Finns det ett samband mellan innovation och hur mycket kontanter cirkulerar i ett samhälle?

Glennow, Emma, Granström, Alexandra January 2019 (has links)
Around the globe, countries move away from banknotes and coins in the favor of digitized payments. A number of findings from academic research conclude various benefits associated with decreased cash usage, such as enhanced economic development, less costs for governments and banks, financial transparency as well as lower economic-related crime rates. In a light of various benefits moving towards cashless payments, it is hypothesized that there also could be a relationship between how innovative a country is and how much cash circulates in economy. The relationship could be both-sided like less cash circulation can trigger innovation and, at the same time, adoption of cashless payments could be driven by how innovative a country is. To be able to investigate a potential correlation, a correlation analysis is conducted between the two variables: an innovation level of a country and cash circulation in econom. The Global Innovation Index score will be used to summarize various factors that provide an overview of national innovation performance, and percentage of Gross Domestic Product (GDP) will be used for currency in circulation. According to the findings, the hypothesis that there is a correlation between cash circulation and innovation performance in a country could not be rejected with a 5% significance level. / Runt om i världen öppnar länder upp för att gå från kontanta betalningsmedel mot digitala betallösningar. Enligt tidigare forskning, leder minskad kontanthantering till flertalet fördelar såsom kraftigare ekonomisk tillväxt, ökad transparens, minskade kostnader samt minskad ekonomiskt brottslighet. De fördelar som kontantlösa betalningar skapar kan vara kopplade till hur innovativt ett land är och hur mycket kontanta medel som cirkulerar i ett lands ekonomi. Ett potentiellt samband mellan mängd kontanter som cirkulerar i ett samhälle och innovation i ett land kan vara tvåsidigt, till exempel att minskade mängder kontanter i ekonomin kan skapa innovation eller så kan kontantlösa betalningar skapas av hög innovationsnivån i ett land. För att kunna undersöka ett potentiellt samband, utförs en korrelationsanalys mellan de två variablerna: nationell innovationsnivå och mängd kontanter i cirkulation i ekonomin. Global Innovation Index används för att sammanfatta olika faktorer som ger en översikt över den nationella innovationsnivå per land och en procentandel av bruttonationalprodukten (BNP) kommer att användas för mängd valuta i omlopp. Enligt framkomna resultat från korrelationsanalysen kunde hypotesen om att det finns ett samband mellan kassaflöde och innovationsnivå i ett land inte förkastas.

[pt] ENSAIOS SOBRE INOVAÇÕES FINANCEIRAS: FEEDBACK TRADING, TRACKING EFFICIENCY E ÍNDICE DE INOVAÇÃO / [en] ESSAYS ON FINANCIAL INNOVATIONS: FEEDBACK TRADING, TRACKING EFFICIENCY AND INNOVATION INDEX

AUGUSTO FERREIRA DA COSTA NETO 19 April 2021 (has links)
[pt] Desde o trabalho seminal conduzido por Schumpeter (1934), vários pesquisadores estudaram a relação entre os gastos com Pesquisa, Desenvolvimento & Inovação (P, D e I) e o desempenho das empresas, obtendo evidências contraditórias entre setores, tamanhos das empresas, geografia e graus de desenvolvimento dos mercados. Esta tese tem como objetivo propor, por meio de três ensaios, a criação de um índice que capture um conjunto de ações de empresas listadas na Brasil, Bolsa, Balcão (B3) que investem e declaram investir em P, D e I, bem como produtos financeiros, notadamente Exchange-traded Funds (ETFs), que, atrelados a este índice, possam contribuir para aumentar o volume de negócios das referidas ações, e assim encorajar mais empresas a se envolverem em atividades de P, D e I, bem como, para as que já o fazem, se comprometerem a divulgar essas ações ao mercado. Os resultados indicam ser possível formar uma carteira de empresas que declaram investimento em P, D e I de tal sorte que o desempenho dessas supere o principal benchmark do mercado brasileiro. Para o caso de produtos atrelados a essa carteira teórica, as evidências apontam para a necessidade de se observar o comportamento dos investidores nestes ativos em mercados emergentes como o brasileiro, bem como desenvolver mecanismos que garantam a aderência do produto ao índice, minimizando erros de precificação. / [en] Since the seminal work conducted by Schumpeter (1934), several researchers have studied the relationship between Research, Development and Innovation (R, D and I) expenditures and firms performance, with mixed outputs among sectors, firms sizes, geography, and markets degrees of development. This thesis aims to propose, through three essays, the creation of an index that captures a set of shares of companies listed in Brasil, Bolsa, Balcão (B3) that invest and declare to invest in R, D and I, as well as financial products, notably Exchange-traded funds (ETFs), which, linked to this index, can contribute to increase the volume of transactions of said shares, and thus contribute to more companies engaging in R, D and I activities, as well as, for those that already do, that commit themselves to divulge these actions to the market. The results indicate that it is possible to form a portfolio of companies that declare investment in R, D and I in such a way that their performance exceeds the main benchmark of the Brazilian market. For products linked to this theoretical portfolio, the evidence points to the need to observe the behavior of investors in these assets in emerging markets such as Brazil, as well as to develop mechanisms that guarantee the adherence of the product to the index, minimizing tracking errors.
