Modeling and evaluation of supply reliability of microgrids including PV and wind power

This paper presents a procedure of supply reliability evaluation for microgrids including renewable energy sources such as wind power and photovoltaics. Microgrid system can be used as a framework to flexibly introduce the renewable energy sources. However, some renewable energy sources affect the power quality negatively. Therefore, it is important to evaluate a microgrid system adequately, and to discuss supply reliability evaluation. In this paper, the authors introduce special reliability indices for microgrids.
