A Study on the Construction of the Flexible Long-Term Generation Mix under Uncertainties of Power System

전력계통(電力系統)의 불확실성(不確實性)을 포함한 유연(柔軟)한 장기전원구성(長期電源構成)의 수립에 관한 연구(硏究)

A new approach using fuzzy dynamic programming is proposed for the flexible long-term generation mix under uncertain circumstances. A characteristic feature of the presented approach is that not only fuzziness in fuel and construction cost. load growth and reliability but also many constraints of generation mix can easily be taken into account by using fuzzy dynamic programming. The method can accommodate arbitrary shape of membership function as well as the operation of pump-generator. And so more realistic solution can be obtained. The effectiveness of the proposed approach is demonstrated by the best generation mix problem of KEPCO-system which contains nuclear, coal, LNG, oil and pump-generator hydro plant in multi-years.
