As the global population increases, so does the demand for water, and the increasing water scarcity is a challenge to the global water sector. It is imperative to take large-scale action in order to make water consumption more sustainable, and information and communication technologies such as smart meters have shown great potential.  Sweden is a country that generally does not face water shortage and where research on smart water metering is still rather new. Previous studies have focused on countries where water scarcity is very common, and more research is needed to examine the generalizability of previous findings. The purpose of this thesis is to examine the possibilities for a large-scale implementation of smart water meters in Swedish households, and the guiding research question is: “What are the main enablers and barriers for a large-scale implementation of smart water meters in Swedish households?”. This thesis is of qualitative and exploratory character, and the study consists of a pre-study, a literature review and interviews. Furthermore, the analysis in this thesis is made using a theoretical framework based on Technological Innovation Systems.  The findings indicate that the possibilities for a large-scale implementation of smart water meters in Swedish households are very good. The most significant enablers are that the Swedish water sector is an open and enabling environment, that smart water meters provide more technological opportunities compared to mechanical meters, and that smart water meters are generally accepted among the actors and considered to be the optimal solution in the future.  On the other hand, there are barriers which need to be addressed for a successful large-scale implementation. The most significant barriers are that smart water meters are more expensive and that there are still some uncertainties regarding the choice of technology such as compatibility issues, risk of lock-in effect, and that the technology quickly becomes outdated. However, these factors may not constitute barriers in the future since they either can disappear with time or some of them could be avoided already today. Therefore, the possibilities for a large-scale implementation are still assessed to be very good. / I samband med den globala befolkningsökningen ökar också efterfrågan på vatten, och den ökande vattenbristen är en utmaning för den globala vattensektorn. Det är nödvändigt att vidta storskaliga åtgärder för att göra vattenförbrukningen mer hållbar, och informations- och kommunikationsteknik såsom smarta mätare har visat stor potential.  Sverige är ett land som vanligtvis inte har vattenbrist och där forskningen om smart vattenmätning fortfarande är i sin linda. Tidigare studier har genomförts i länder där vattenbrist är mycket vanligare, och mer forskning behövs för att undersöka generaliserbarheten av tidigare resultat. Syftet med detta examensarbete är att undersöka möjligheterna för en storskalig implementering av smarta vattenmätare i svenska hushåll, och arbetets forskningsfråga är: ”Vilka är de viktigaste möjliggörarna och hindren för en storskalig implementering av smarta vattenmätare i svenska hushåll?”. Detta examensarbete är av kvalitativ och utforskande karaktär, och studien består av en förstudie, en litteraturstudie samt intervjuer. Vidare görs analysen i detta examensarbete med hjälp av ett teoretiskt ramverk baserat på Teknologiska innovationssystem.  Resultaten i denna studie tyder på att möjligheterna för en storskalig implementering av smarta vattenmätare i svenska hushåll är mycket goda. De viktigaste möjliggörarna är att den svenska vattensektorn är en öppen och möjliggörande miljö, att smarta vattenmätare ger fler tekniska möjligheter jämfört med mekaniska mätare, och att smarta vattenmätare är allmänt accepterade bland aktörerna och anses vara den optimala lösningen i framtiden.  Det finns dock vissa hinder som måste åtgärdas för att uppnå en framgångsrik storskalig implementering. De viktigaste hindren är att smarta vattenmätare är dyrare och att det fortfarande finns vissa osäkerhetsfaktorer när det gäller val av teknik, t.ex. kompatibilitetsproblem, risk för inlåsning, och att tekniken snabbt föråldras. Det är dock möjligt att dessa faktorer inte utgör hinder i framtiden eftersom de antingen kan försvinna med tiden eller undvikas och hanteras redan idag. Därför bedöms möjligheterna för en storskalig implementering av smarta vattenmätare i svenska hushåll ändå vara mycket goda.

This research is a case study with the purpose of transforming Búzios into an intelligent city, as it is published by the municipal administration. The study aimed to verify if all the projects presented were executed and if the concepts of sustainability, rationality and loss control are being applied. The approach defined for research was qualitative, verifying the facts and seeking to clarify the dynamics of social relations, through a descriptive and exploratory research. During the visit to the city information was collected through interviews and direct observations, among the interviews were qualified 20 residents and collected 202 photographs. Among the projects implemented and in operation are three generators of photovoltaic energy, as for the projects implemented and that presented discontinuity and failures in its operation are the intelligent LED lighting system, the free internet system project, the projects with the systems of generation of aerogenerator energy, power network automation projects and installation projects of smart meters. During the technical visit, it was not possible to identify characteristics or contributions that define the city of Búzios-RJ, as the first intelligent city in Latin America, as little as an intelligent city, once the projects executed show flaws, a small part of the city was contemplated, the population does not have knowledge about the project, lack of continuity and governance. Although the projects listed make sense as components of an intelligent city with an intelligent electric grid, it was not possible to characterize the city as "intelligent" since the projects did not show, in their majority, effectiveness and scope enough to do so. The city can, however, become intelligent by expanding the reach and effectiveness of the projects. / Ao almejar a construção de uma cidade inteligente existe a necessidade de identificar os processos que podem ou não contribuir para sua construção e quais os desafios a serem superados, levando-se em conta os aspectos da vida urbana, como mobilidade, segurança, sistemas de comunicação, saneamento e também para o sistema elétrico. A presente pesquisa é um estudo de caso tendo como objeto a transformação de Búzios em cidade inteligente, conforme é divulgado pela administração municipal. O estudo teve como objetivo verificar se todos os projetos apresentados foram executados e se os conceitos de sustentabilidade, racionalidade e controle de perdas estão sendo aplicados. A abordagem definida para pesquisa foi qualitativa, verificando os fatos e buscando esclarecer a dinâmica das relações sociais, por meio de uma pesquisa descritiva e exploratória. Durante a visita a cidade foram coletadas informações por meio de entrevistas e observações diretas, dentre as entrevistas foram qualificados 20 moradores e coletadas 202 fotografias. Dentre os projetos implementados e em funcionamento estão três geradores de energia fotovoltaica, quanto aos projetos implementados e que apresentaram descontinuidade e falhas no seu funcionamento estão o sistema de iluminação a LED inteligente, o projeto de sistema de internet gratuita, os projetos com os sistemas de geração de energia aerogerador, os projetos de automação da rede de energia e os projetos da instalação dos medidores inteligentes. Durante a visita técnica não foi possível identificar características ou contribuições que definam a cidade de Búzios-RJ, como a primeira cidade inteligente da América Latina, tão pouco como cidade inteligente, uma vez que os projetos executados apresentaram falhas, uma pequena parte da cidade foi contemplada, a população não possui conhecimento sobre o projeto, falta de continuidade e de governança. Embora os projetos elencados façam sentido como componentes de uma cidade inteligente, com rede elétrica inteligente, não foi possível caracterizar a cidade como "inteligente" dado que os projetos não apresentaram, em sua maioria, efetividade e alcance suficiente para isso. A cidade pode, no entanto, tornar-se inteligente ao ampliar o alcance e a efetividade dos projetos.

Tarifa Time-of-use tariffs are one way of encouraging consumers to carry out the transfer of load to off-peak intervals, thus making unnecessary new and high investments in generation and transmission and distribution infrastructure. This is therefore a tool for the expansion of energy efficiency, in a new concept of electricity grids, the Smart Grids. However, for this type of charging to be applied, new and modern meters are required, those with the capacity to differentiate consumption hours and that can inform the consumer properly. In this sense, this work is aimed at the development of a meter with an open source platform, in the case Arduino, associated to Analog Devices ADE7753 integrated circuit, transmitting information through IEEE802.11 (Wi-Fi) network, and through an IoT (Internet of Things) platform, to make an assessment whether adoption of the White Tariff is financially beneficial to the consumer in a simple and interactive way. / As tarifas hor?rias s?o uma das formas de incentivar os consumidores a realizarem a transfer?ncia de carga para intervalos fora de ponta, fazendo assim desnecess?rios novos e altos investimentos em gera??o e infraestrutura de transmiss?o e distribui??o.

This Master’s thesis deals with design of a new method for voltage quality benchmarking using voltage quality index. This index should determinate total voltage quality in the power grid and compare voltage quality in different places. There is design of several algorithms which value measured parameters in this thesis. The best suitable algorithm is selected. Program for this algorithm was compiled in GUI Matlab. The algorithm is verified by using measured parameters in this program. The last part of this thesis is focused on possible usage of created algorithm.

This thesis addressed the need for improved analysis and interpretation of primary meter half-hourly energy consumption data. The current work offers a novel benchmarking technique that was tested for 6 types of municipal buildings. This approach is different from conventional annual benchmarking mainly because it uses electricity and gas data in half-hourly periods, together with outside temperature data. A survey to European local authorities’ metering and monitoring practices was conducted in order to assess municipal energy managers' current procedures and needs in terms of data analysis to assess building energy performance and to identify potential energy saving opportunities. The benchmarking approach was developed considering the energy managers’ needs, but also the state-of the art in terms of building energy monitoring techniques, particularly building energy signatures, and the analysis techniques used on electricity grid demand forecasting. The benchmarking approach is based on the use of a metric composed of several indicators that are related to the load demand shape profile and the building energy signature. The comparison of indicators for buildings of the same type using standard scores identifies uncommon load demand profile characteristics and/or gas dependency on outside temperature in specific buildings. The metric is able to support the identification of potential energy wastage, which is linked to the detection of opportunities to save energy. The benchmarking technique was tested in 81 municipal building owned by Leicester City Council. This methodology can be applied to any non-domestic building equipped with primary meters for registering half-hourly electricity and gas consumption. In theory, this approach can also be applied to residential buildings, and to other short time series data types, for example quarter-hourly or 10 minutes interval data. The main contribution of this thesis is to improve the objectivity of building primary meter half-hourly electricity and gas consumption data analysis and interpretation by using quantitative parameters, instead of subjective visualisation techniques. The interpretation of building consumption data in short time series periods can now be streamlined, automated and perhaps incorporated in existing energy analysis software. This thesis raises questions that can lead to future research projects aiming to improve the metric and also to enlarge the scope of its application to national and European scale, to other building types and to other utilities.
