Analysis of Short-Circuit Calculation in Microgrid with Wind/Solar Micro-Sources Based on IEC STANDARD 60909

Abstract:

Microgrid are LV or MV electric networks which utilize various distributed generators (DG) to serve local loads.In this paper an equivalent model of a hybrid system including wind power and solar power generating units has been built based on the mathematical models of wind turbine(WT) and photovoltaic(PV).Control strategies of the converters have been also developed. The short-circuit current and voltage levels of the microgrid have been calculated respectively based on the IEC 60909 standard corresponding to the occurrence of a three-phases short-circuit at the Point of the Common Coupling(PCC). Simulation results verified that the micro sources and microgrid built in this paper can simulate the actual system operation very well, and it can provide a simulation platform for further study of operation characteristics of system-integrated microgrid.
