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划定成本2部分,容量使用同定成本根据交易对线路有功潮流的使用度来分配;可靠悱固定成本根据线路的叮靠性贡献来分配,并计及了线路潮流变化、停运概率和停运时问的影响。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。
Fixed transmission cost is divided into fixed capacity utilization cost and fixed reliability cost. Fixed capacity utilization cost is allocated according to the utilizing extent of line active power flow by individual transaction; fixed reliability cost is allocated according to the contribution of individual transaction to the reliability in which the impacts of line power flow variation, outage probability and outage time are taken into account. The proposed method is suitable for such electricity market in which the pool and bilateral transaction coexist. The proposed method can either satisfy circuital law or give good economical signal. Simulation results verify the effectiveness of the proposed method.
