A Study on the Avioded Generation Costs of Indepndent Power Producers Using Probabilistic Load Decrement Method

확률적 부하감소법을 이용한 민자발전소의 회피비용 계산 방법론 연구

This Paper Presents a new analytic load decrement method for the evaluation of avoided generation costs of independent power producers (IPPs), named as probabilistic load decrement method. Unlike conventional load decrement methods, the proposed method exactly consider the random outage characteristic of a generating unit, economic dispatch order, and the resulting loss of load probability. Therefore, we can Provide the exact generation avoided costs of an IPP by applying the developed method. In the case studies, we have shown the correctness and effectiveness of the method, and compared with conventional load decrement methods.
