A Study of Long-Term Generation Expansion Planning Using Nonlinear Invest Cost Function

비선형 투자비 함수를 이용한 장기 전원개발계획 수립에 관한 연구

Generally, average invest cost is widely used for expansion planning of generation in power system. But, other cost which is followed by adding generating capacity in electric system is increased in accordance with increasing plant reasons. In this study, we represent the invest cost with quadratic function and analyze its effect on the expansion planning. It is hoped that this method is used in expansion planning of generating system.
