송전계통을 고려한 계통운용자의 발전기 예방정비계획 알고리즘에 관한 연구

초록

- In competitive electricity markets, the System Operator (SO) coordinates the overall maintenance schedules when the collective maintenance schedule reported to SO by Gencos not satisfy the specified operating criteria, such as system reliability or supply adequacy. This paper presented a method that divides generator maintenance scheduling of the SO into a master-problem and a sub-problem. Master-problem is schedule coordination and sub-problem is DC-optimal power flow. If sub-problem is infeasible, we use the algorithm of modifying operating criteria of master-problem. And, the SO should use the open information only, because the information such as cost function of a generator and bidding price is highly crucial for the strategies of profit maximization.
