ENSAIOS DE INVERSORES PARA SISTEMAS FOTOVOLTAICOS CONECTADOS À REDE: RESULTADOS E ANÁLISE DE CONFORMIDADE José Cesar de Souza Almeida Neto – André Mocelin – Roberto Zilles – Universidade de São Paulo, Instituto de Energia e Ambiente João Tavares Pinho – Universidade Federal do Pará-GRID-TIE PHOTOVOLTAIC SYSTEM INVERTER TEST: RESULTS AND CONFORMITY ANALISYS BRASIL

Resumo. 
No Brasil, a necessidade crescente por sistemas de geração solar fotovoltaica conectados à rede de distribuição levou ao desenvolvimento de normas brasileiras para a conformidade de inversores. Assim, de forma a atender à população em geral, foi publicada a Portaria 357, de 01 de agosto de 2014, do Instituto Nacional de Metrologia, Qualidade e Tecnologia (INMETRO), que inclui inversores para conexão à rede de potência nominal até 10 kW no Programa Brasileiro de Etiquetagem (PBE). Por possuir os equipamentos necessários para a realização dos ensaios de conformidade com a portaria 357, o Laboratório de Sistemas Fotovoltaicos (LSF) do Instituto de Energia e Ambiente da Universidade de São Paulo passou então a ser o primeiro laboratório acreditado pelo INMETRO para a realização desses ensaios. Este trabalho tem como objetivo resumir as experiências de aplicação das normas brasileiras no ensaio de inversores para o PBE no LSF, sendo apresentados os resultados obtidos nos ensaios de 15 inversores ao longo de três anos de operação da bancada de ensaio para sistemas conectados à rede, e a descrição das não conformidades encontradas. A partir desses ensaios conclui-se que, embora as normas brasileiras exijam rigor em seus requisitos, existem inversores capazes de atender aos requisitos normativos brasileiros, assim como existem inversores que necessitam de implementações nos respectivos firmwares de controle e sistemas de comunicação para conseguirem atender a todos os requisitos.

Abstract - In recent years, technology for storing a preliminary power or a surplus of photovoltaic energy is required. This technique, as well as store a preliminary energy and improve the reliability of the gird safety. This system can plan a efficient power generation through the flexibility of the power supply from the perspective of not only provider but also user. Accordingly, the realization of the smart grid can be expected. This paper proposes a hybrid PCS using a photovoltaic and a lithium-polymer battery with the characteristics of high density energy. The main energy source of a hybrid PCS is a photovoltaic, grid and the auxiliary energy source is a lithium-polymer battery. The operation of a proposed system in this paper is verified with simulation and experimental results.

Design and control of a PV active generator with integrated energy storages : application to the aggregation of producers and consumers In an urban micro smart grid-THESE Présentée en vue d’obtenir le grade de DOCTEUR en Spécialité : Génie Electrique par Di LU DOCTORAT DELIVRE PAR L’ECOLE CENTRALE DE LILLE







General Introduction
Targets for future sustainable electrical networks The electricity is suffering from a constraint irrefutable: At any moment, electrical systems must ensure a balance between production and consumption, while maintaining a satisfactory voltage. Historically, grid reliability was mainly assured by having excess capacity in the system with unidirectional flow to dispersed consumers from centrally dispatched large power plants. To combat climate change and increase the EU’s energy security while strengthening its competitiveness, the EU Heads of State and Government have set a series of demanding climate and energy targets to be met by 2020, known as the "20-20-20" targets: • A reduction in EU greenhouse gas emissions of at least 20% below 1990 levels, • A 20% reduction in primary energy use compared with projected levels, to be achieved by improving energy efficiency, • 20% of EU energy consumption coming from renewable resources. Current limitation of the PV resource Today, renewable energies are considered as a potential solution for greenhouse gases emissions reduction and energy safety. Fueled by economic, environmental and social drivers, the penetration of photovoltaic generators rises in distribution networks. Thanks to its operation without noise and gas emission, it can be easily installed outdoor and on roofs. But the development of grid-connected PV generation is limited by the intermittent power generation and time-lag between the PV electrical production and the real consumption. A massive deployment of PV systems complicate the balancing between production and consumption, that may cause blackouts if it is disturbed A new concept: the PV based active generator Because of the intermittency of PV power generation, PV panels can not be used as a stable, reliable and controllable power source and can not provide ancillary services like conventional generators. The topic of this thesis is the transformation of a PV generator into an active generator by using an embedded energy storage system and a local energy management system for the coordination of inner sources. Long-term energy storage batteries are used to shave the midday PV power peak and provide a complementary power supply during the night. Fast dynamic ultracapacitors storage can smooth the generated PV power, compensate the power gap and absorb the instantaneous high power peaks. Local controller for a dispatched management Three sources with different characteristics must be coordinated inside the PV active
generator. So for ensuring an optimal operation, a local energy management system of the PV
based active generator has to be developed to enable:
• the management of the renewable energy intermittency and resources,
• the quality of power supply,
• the energy level management,
• the power system protection,
• the provision of grid ancillary services.
This PV based active generator is then an additional controllable dispersed generation,
which have to be dispatched. In the context of a large scale development of PV based active
generators, the operation mode of the electric network will have to be changed.
