Effect of multi-BESS coordinated WTGs on power system reliability

In this paper, the effect of energy storage system(ESS) is studied in reliability view of point and to reduce the volatility of wind turbines with high output volatility. The wind turbine generators(WTG) in power system are rapidly increasing it can create power fluctuations and affect the stability of the power system. Therefore, the output volatility of these WTGs would be reduced by installing ESS. This paper proposes new method for evaluating reliability power system including multi-ESS combined WTG. Monte Carlo simulation method is used in this paper. In addition, ESS reliability evaluation function is developed, in this paper, to investigate the efficiency of model system similar to Jeju Island power system dimension.
