Reliability evaluation of stand-alone hybrid microgrid using Sequential Monte Carlo Simulation

Adequacy assessment of a stand-alone microgrid including diesel generator (DG), Micro Gas Turbine(MGT), Wind Turbine Generator(WTG), and Photovoltaic(PV) with different configurations is carried out using Sequential Monte Carlo Simulation(SMCS) method. To obtain the output power of WTG and PV, some atmospheric data such as wind speed, solar irradiation, and ambient temperature data are needed. Weibull distribution is used to obtain these data. To obtain the adequacy model of DG and MGT a two-state reliability model is employed. A combination of the two-state reliability model and output power can be also used to build the generation model of WTG and PV. In addition, the generation model of system compares with IEEE Reliability Test System (IEEE RTS) load model and adequacy indices are then achieved. Simulation results corroborate the flexibility of SMSC in risk evaluation of both stable and unstable resources.
