Research on the type of load of accessing to microgrid based on reliability

Abstract

The microgrid provides a new form of Distributed Generation accessed to distribution network. With the development and application of microgrid technologies, its ability to meet the power supply reliability needs of loads in microgrid has become a problem that should be solved. To this end, the paper divides the loads according to the power supply reliability, builds a microgrid model constituting of wind/photovoltaic power /independent storage power, and investigates the reliability evaluation method based on Monte Carlo simulation. By an example of IEEE-RBTS system, the paper compares the reliability level of loads in normal distribution network with those in the microgrid, finally draws the conclusion, the third-class load is the most suitable load accessed to microgrid.
