Abstract

Around the word a significant number of villages may never have access to electricity due to their remoteness. For the people living in these isolated communities, access to renewable energy sources is the only solution to meet their energy needs. In these communes the electricity is mainly used for household purposes such as lighting. One of the main problems of such systems, located in isolated areas of difficult access, is the reliability. The coordination protection and operation, distribution network, inverters, control strategies, and maintenance are aspects that must be well designed to get a reliable system. Furthermore, in these applications the system should have the following features: expansion flexibility and robustness, high efficiency, and adequacy to operate in adverse environmental conditions. The results presented in this paper will address these problems with special attention to the control strategies, and system operation. The paper will present experimental results showing the robustness and viability of a pilot renewable hybrid electrical generation system in the Lençóis´s Island, northeast of Brazil.
