Reliability assessment of integrated wind-storage systems using Monte Carlo simulation

Due to increasing demand for electrical power over the world, the integration of non-conventional power sources, such as wind generators, has become a necessity. This paper introduces a reliability-assessment method for an wind-storage system connected to local loads. Random outages are imposed to load chronological data to simulate grid failures using the Monte Carlo simulation method. A comparison among the grid-connected load, the hybrid system that contains the wind generator with and without energy storage, and the stand-alone wind power system is included. This comparison is in terms of load reliability indexes such as availability, average interruption duration, and average interruption frequency. A sensitivity analysis is performed on different cases to investigate the effect of a system's parameter.
