Simulação e análise de um sistema de geração fotovoltaica conectado a uma microrrede

Abstract

Distribution networks are undergoing changes that promote dristibuted control and decision making, facilitating the penetration of distribution generation and energy storage technologies. Since 2012, as a result of normative resolution 482, instituted by the National Electric Energy Agency, the number of distributed photovoltaic generation installations has been growing in Brazil. One of the great advantages that distributed generation provides is the possibility of application in microgrids, which in turn, can improve the continuity of energy supply to consumers; reduce harmful emissions to the environment and can be used as an auxiliary energy source to support the main network. But the insertion of distributed generation in a network can modify operational aspects such as coordination and selectivity of protection, and the analysis of microgrids with distributed generation tends to be complex. Taking into account the national norms that regulate distributed generation, this work proposes a computational approach to the situation. The objective is to deliver a microgrid model with photovoltaic generation that also includes a specific protection switch for the photovoltaic inverter, that acts in detriment of the ABNT NBR 16149 standard.
