Abstract

Brazil is taking the first steps toward to spread the medium and low power distributed generation. Consequently, the academic researcher in this area earns an additional relevance, in order to develop and to improve in the devices that will begin to be installed in the country, as well as regarding of theirs control strategies. Conventionally and commercially, photovoltaic systems are limited to only inject active power locally in the grid, however, within its rated capacity, other functions may be added, such as the active compensator or the STATCOM. This project aims to study and to develop photovoltaic systems capable to inject active power in the grid and, simultaneously, to perform a distributed and cooperative compensation with other distributed generators to improve the efficiency and the power quality outside and/or inside of a microgrid under unbalances and distortion waveforms operating conditions. Control of several single phase and/or three-phase photovoltaic systems will be studied, even focusing on the compensation of nonlinearities and unbalanced loads. Also, the possibility to compensate the voltage grid unbalance through distributed generators emulating distributed STATCOMs will be investigated. For this goal, it will be tried to apply the Steinmetz's principles. Moreover, the Conservative Power Theory, which allows the identification of current components, will be applied together with a multi-agent system to assist the exchange of information among photovoltaic units, optimizing the cooperative compensation among them. Beyond the multi-agent system, other techniques for cooperative control, and/or communication among units will be studied and evaluated, for example, token ring control; plug and play control; surround control etc. Simulation and experimental results will be used to evaluate the studies.
