Full textA mathematical framework based on Pulse Width Modulation theory is developed for the remote ON/OFF switching of residential appliances. Load Management System performs the switching actions on load groups in such a way that the resulting net demand of the appliances matches with a Load Reduction Target. The Load Reduction Target is obtained by modelling load groups as new generation resources into generation scheduling functions. The results of the proposed approach are compared with the results of the current practices and it is shown that the proposed scheme is an effective and flexible method that not only can realize the general form of Load Reduction Targets but also it is capable of error compensation, payback power regulation, switching schedules, incremental update and handling unequal peak powers of load groups.
For continuous control schemes, it is shown that during the control period, diversified states of the appliances do not change drastically and room temperatures within each load group are largely similar. Optimal control strategies are generated by employing Priority List, Linear Programming and Forward Dynamic Programming. The results show a close match between the Load Reduction Target and appliances' demand during control period.
Both methods are efficient and flexible. They allow incremental updating of schedules. Therefore, they are good candidates for use in real time operations.

Full textThis thesis presents a method to disaggregate electrical appliances in the load profile of residential buildings. In recent years, energy monitoring has obtained significantly popularity in private and industrial environment. With algorithms of the disaggregation, the measured data from so-called smart meters can be used to provide more information of the energy usage. One method to receive these data is called non-intrusive appliance load monitoring.The main part of the thesis can be divided into three parts. At first, an own measurement system was developed and verified. With that system, real data sets can be generated for the development and verification of the disaggregation algorithms. The second part describes the development of an event detector. Different methods are presented and evaluated, with which the switching times of the appliances can be detected in the load profile. The last part describes a classification method. Different features are used for the classification. The classifier recognizes and labels the individual appliances in the load profile. For the classification different structures of artificial neural network (ANN) are compared

The demand of electric appliances has been increasing with promoting of new technology. On the other hand、the tremendous quantity of waste electric appliances caused a great deal of serious problems、especially pollution in environment. Since waste electric appliances still can be reused or recycled、and make value and benefits、many developed countries have emphasized the recovery process of waste electric appliances and legislated for managing the reverse logistics and regulating the producers』 responsibility. As for this issue in Taiwan、there is little attention and lake of complete regulations. Thus、this study focuses on investigating the process of reverse logistics in waste electric appliances. In this study、the data are collected to figure out the constitution of recycling system from experts and papers、and to make comparison of recycling systems between several developed countries. Furthermore、we refer to the results of analysis and consider the current situation in Taiwan、and try to design recycling system of waste electric appliances. The study concludes that the operation of close-looped systems is more efficiency because the government can control the process and quantity of recovery. We suggest that producers』 responsibility should be taken into account in the recycling system. The transportation must be assigned and monitored、and the control center must be built up to monitor operation of recycling system. Additionally、the mark tags have to be designed to tape every waste when collecting. Besides、secondhand sales should be involved in recycling system. The government should verify the quality of reused electric appliances to protect the right of consumers.

When talking about design, aside from the balance between functionality and aesthetics, it also needs to serve as a tool to trigger thinking. This study begins by reflecting consumerism, through literature survey and material exploration it finally focuses on the growing problem of e-waste. It attempts to change the relationship between human and appliance by emphasizing design and aesthetics, and introduce warmth and human nature into the cold-heart electronic products. For the purpose of seeking the overlap regions between electrical equipment and crafts, I select two simple objects, lamp and loud-speaker, to create three items: “My Crystal Light”, “Loose Light”, and “Internal Sound”. Cooperating with electronic professional during the developing process, I try to understand the mode of operation in the internal circuit and function of each electronic components form the designer’s point of view for its unique creation. The records with texts and images, not only offer the followers relevant material, they enable readers to have a broader understanding and imagination into the internal of electrical equipment.

Full textO consumo de energia tem vindo a crescer na União Europeia todos os anos, sendo de prever que, a curto prazo, se torne insustentável. No sentido de prevenir este cenário, a Comissão Europeia decidiu definir uma Estratégia Energética para a União Europeia, destacando dois objetivos: aumentar a eficiência energética e promover a descarbonização. Atualmente, cerca de 72% dos edifícios existentes na União Europeia não são energeticamente eficientes. Este problema motivou-nos à pesquisa e criação de soluções que permitam uma melhor avaliação do consumo energético por dispositivos elétricos em edifícios residenciais. Neste contexto, o trabalho desenvolvido nesta tese consiste no desenho de uma solução de monitorização remota que recolhe informações de consumo energético recorrendo a técnicas de intrusive load monitoring, onde cada dispositivo elétrico individual é continuamente monitorizado quanto ao seu consumo energético. Esta abordagem permite compreender o consumo de energia, em tempo real e no dia-a-dia. Este conhecimento oferece-nos a capacidade de avaliar as diferenças existentes entre as medições laboratoriais (abordagem utilizada no sistema de rotulagem de equipamentos elétricos de acordo com a sua eficiência energética) e os consumos domésticos estimados. Para tal, nesta tese exploram-se abordagens de machine learning que pretendem descrever padrões de consumo, bem como reconhecer marcas, modelos e que funções os dispositivos elétricos estarão a executar. O principal objetivo deste trabalho é desenhar e implementar um protótipo de uma solução de IoT flexível e de baixo custo para avaliar equipamentos elétricos. Será utilizado um conjunto de sensores que recolherá dados relacionados com o consumo de energia e os entrega à plataforma SATO para serem posteriormente processados. O sistema será usado para monitorar aparelhos comumente encontrados em residências. Além disso, o sistema terá a capacidade de monitorizar o consumo de água de aparelhos que necessitem de abastecimento de água, como máquinas de lavar e de lavar louça. Os dados recolhidos serão usados para classificação dos aparelhos e modos de operação dos mesmos, em tempo real, permitindo fornecer relatórios sobre o consumo energético e modo de uso dos aparelhos, com grande grau de detalhe. Os relatórios podem incluir o uso de energia por vários ciclos de operação. Por exemplo, um aparelho pode executar vários ciclos de operação, como uma máquina de lavar que consume diferentes quantidades de energia elétrica e água consoante o modo de operação escolhido pelo utilizador. Toda a informação recolhida pode ser posteriormente utilizada em novos serviços de recomendação que ajudaram os utilizadores a definir melhor as configurações adequadas a um determinado dispositivo, minimizando o consumo energético e melhorando a sua eficiência. Adicionalmente toda esta informação pode ser utilizada para o diagnóstico de avarias e/ou manutenção preventiva. Em termos de proposta, o trabalho desenvolvido nesta tese tem as seguintes contribuições: Sistema de monitorização remota: o sistema de monitorização desenhado e implementado nesta tese avança o estado da arte dos sistemas de monitorização propostos pela literatura devido ao facto de incluir uma lista aprimorada de sensores que podem fornecer mais informações sobre os aparelhos, como o consumo de água da máquina de lavar. Além disso, é altamente flexível e pode ser implementado sem esforço em dispositivos novos ou antigos para monitorização de consumo de recursos. Conjunto de dados de consumo de energia de eletrodomésticos: Os dados recolhidos podem ser usados para futura investigação científica sobre o consumo de consumo de energia, padrões de uso de energia pelos eletrodomésticos e classificação dos mesmos. Abordagem de computação na borda (Edge Computing): O sistema de monitorização proposto explora o paradigma de computação na borda, onde parte da computação de preparação de dados é executada na borda, libertando recursos da nuvem para cálculos essenciais e que necessitem de mais poder computacional. Classificação precisa de dispositivos em tempo real: Coma proposta desenhada nesta tese, podemos classificar os dispositivos com alta precisão, usando os dados recolhidos pelo sistema de monitorização desenvolvido na tese. A abordagem proposta consegue classificar os dispositivos, que são monitorizados, com baixas taxas de falsos positivos. Para fácil compreensão do trabalho desenvolvido nesta tese, de seguida descreve-se a organização do documento. O Capítulo 1 apresenta o problema do consumo de energia na União Europeia e discute o aumento do consumo da mesma. O capítulo apresenta também os principais objetivos e contribuições do trabalho. No Capítulo 2 revê-se o trabalho relacionado em termos de sistema de monitorização remota, que inclui sensores, microcontroladores, processamento e filtragem de sinal. Por fim, este capítulo revê os trabalhos existentes na literatura relacionados com o problema de classificação de dispositivos usando abordagens de machine learning. No Capítulo 3 discutem-se os requisitos do sistema e o projeto de arquitetura conceitual do sistema. Neste capítulo é proposta uma solução de hardware, bem como, o software e firmware necessários à sua operação. Os algoritmos de machine learning necessários à classificação são também discutidos, em termos de configurações necessárias e adequadas ao problema que queremos resolver nesta tese. O Capítulo 4 representa a implementação de um protótipo que servirá de prova de conceito dos mecanismos discutidos no Capítulo 3. Neste capítulo discute-se também a forma de integração do protótipo na plataforma SATO. Com base na implementação feita, no Capítulo 5 especificam-se um conjunto de testes funcionais que permitem avaliar o desempenho da solução proposta e discutem-se os resultados obtidos a partir desses testes. Por fim, o Capítulo 6 apresenta as conclusões e o trabalho futuro que poderá ser desenvolvido partindo da solução atual.
Energy consumption is daily growing in European Union (EU). One day it will become hardly sustainable. For this not to happen European Commission decided to implement a European Union Strategy, emphasizing two objectives: increasing energy efficiency and decarbonization. About 72% of all buildings in the EU are not adapted to be energy efficient. This problem encourages us to create solutions that would help assess the energy consumption of appliances at residential houses. In this thesis, we proposed a system that collects data using an intrusive load monitoring approach, where each appliance will have a dedicated monitoring rig to collect the energy consumption data. The proposed solution will help us understand the real-life consumption of each device being monitored and compare the laboratory measurements observed versus domestic consumption estimated by the energy consumption based on the EU energy efficiency labelling system. The system proposed detects device consumption patterns and recognize its brand, model and what actions that appliance is executing, e.g., program of washing in a washing machine. To achieve our goal, we designed a hardware solution capable of collecting sensor data, filtering and send it to a cloud platform (the SATO platform). Additionally, in the cloud, we have a Machine Learning solution that deals with the data and recognizes the appliance and its operation modes. This recognition allows drawing a device/settings profile, which can detect faults and create a recommendation service that helps users define the better settings for a specific appliance, minimizing energy consumption and improving efficiency. Finally, we examine our prototype approach of the system implemented for targeted objectives in this project report. The document describes the experiments that we did and the final results. Our results show that we can identify the appliance and some of its operation modes. The proposed approach must be improved to make the identification of all operation modes. However, the current version of the system shows exciting results. It can be used to support the design of a new labelling system where daily operation measures can be used to support the new classification system. This way, we have an approach that allows improving the energy consumption, making builds more efficient.

Full textOs eletrodomésticos ajudam-nos diariamente com as tarefas domésticas. Com o uso estes começam a desenvolver anomalias que se traduzem em consumos de energia mais elevados e, muita das vezes, em avarias que obrigam a reparações que representam um incómodo e um custo inesperados. Neste projeto iniciou-se o desenvolvimento de um sistema de monitorização avançada para eletrodomésticos que permite detetar falhas antecipadamente através da análise detalhada de parâmetros operacionais. Possibilitando assim um maior controlo dos gastos energéticos e das reparações do eletrodoméstico.O sistema reutiliza uma tomada desenvolvida na VPS, a idPlug, que possibilita a medição de parâmetros elétricos (corrente, tensão, potência) e análise do sinal de corrente usando técnicas no domínio da frequência. A deteção de falhas baseia-se num método que compara a evolução dos máximos da transformada de Fourier da corrente. Para simplificar a operação do sistema foi desenvolvido interface web local que permite visualizar os dados e parametrizar o dispositivo.Os requisitos especificados foram verificados através de um conjunto de testes utilizando inicialmente um motor sem carga. Posteriormente, o sistema foi testado usando um mini-frigorífico, tendo o dispositivo detetado corretamente todos os arranques do motor. Em seguida, realizaram-se testes com uma máquina de lavar onde se verificaram falhas no algoritmo implementado devido ao facto deste eletrodoméstico possuir vários elementos de carga (motores e resistência de aquecimento) e diferentes ciclos de lavagem. Assim, a evolução futura do algoritmo deverá permitir a identificação de diferentes ciclos de operação. De igual forma, a deteção de falhas poderá incluir a análise de longo termo dos dados recolhidos usando técnicas de reconhecimento de padrões e agregação.
Home appliances help us with domestic tasks every day. With usage, they start to develop small anomalies which translate into higher energy consumptions and, most of the times, faults that require repairs that represents an unwanted extra cost. This project started the development of an advanced monitoring system for home appliances, which allows detecting anomalies through a detailed analysis of operational parameters. So, this system allows for better control of energy and appliance repair costs.The system reuses a device developed in VPS, the idPlug. This device measures electrical parameters (current, voltage, power) and analyses the current signal using techniques in the frequency domain. The fault detection is based on a method that compared the maximums of the current Fourier transform. To simplify the system operation a local web interface was developed which allows data visualization and device parameterization.The specified requirements were checked by a set of tests using a motor with no load. Afterwards, the system was tested using a mini-refrigerator where the number of motor starts correctly identified. Then, the system was tested using a washing machine that revealed some shortcomings in the implemented algorithm due to the existence of several load elements (motors and heating elements) and different washing cycles. So, a future algorithm evolution should allow the washing cycle identification. Likewise, fault detection may include a long-term analysis of the collected data using pattern recognition and aggregation techniques.

Microsoft released the Kinect in 2010. It can capture the user’s depth information and use the body to replace the traditional remote control machine, so every player can feel unprecedented entertainment experience. Kinect is reasonable and powerful, so it is attractive to a lot of developers in industry or researchers to develop innovated applications. The Kinect sensor has the limitation in the detection angle and range. If user will want to control many appliances, every appliance must prepare its dedicated device. According to this research, it only needs one Kinect that can control many appliances. Besides, this research uses an Arduino as IR LED controller to send remote control signals to operate machine. So user can use his hands to replace the remote control at home. Therefore, Kinect and Arduino can let our life be simple. When a user enters the sensing area, our system can detect the human skeleton by Microsoft Kinect SDK. Our system can also calculate the 3D transform to recover user''s pose. If the user raises his hand to point at an appliance, he can specify that device to power on/off and use his gestures to control it. Four gestures are also defined for the most important control signals such as forward, backward, up and down. Our system can also extend to eight gestures for extra commands including escape command. The control system, without traditional remote controller on hand, can make the appliances control easier in digital home.
