计算输电线路固定成本时将其分成容量使用固定成本和可靠性固定成本2部分,容量使用固定成本根据交易对线路有功潮流的使用度来分配;可靠性固定成本根据线路的可靠性贡献来分配,并计及了线路潮流变化、停运概率和停运时间的影响。该方法适用于联营和双边交易共存的电力市场,既满足电路定律,又给出了良好的经济信号。仿真算例验证了方法的有效性。
The fixed cost of a transmission line is divided into two parts: the fixed cost and the fixed cost. The fixed cost of capacity is allocated according to the usage of the active power flow of the line according to the transaction. The fixed cost of reliability is allocated according to the contribution of the reliability of the line, And takes into account the impact of changes in line flow, outage probability and outage time. This method is suitable for the electricity market where the joint venture and the bilateral trade coexist, which not only satisfies the circuit law but also gives a good economic signal. The simulation example verifies the effectiveness of the method.
