探讨了电力市场多种交易模式下输电网固定成本的分摊问题。直接以交易功率为自变量,基于支路耗散功率转归分量法,推导了一种将线路潮流同时自然地转归给各个交易的解析方法,从而在物理层面上建立了交易量与线路潮流之间的量值关系。结合输电网固定成本及交易对线路有功潮流的使用程度,进一步提出了将输电网固定成本转归给各个交易的具体策略。该方法适用于混合交易模式的电力市场。它既满足电网的物理特性,又能提供良好的经济信号。仿真结果验证了文中方法的有效性。
The allocation of fixed transmission cost under hybrid transactions modes is investigated. Based on the algorithm of imputation of an impedance-branch dissipation power, an accurate analytical method for imputing power flow naturally and simultaneously to individual transaction is derived mathematically, where transaction power is the independent variable. Both the fixed cost and the imputation of branch power flow to transaction are analyzed to develop a concrete method for imputing fixed cost to individual transaction. The proposed method is applicable for electricity markets containing pool and bilateral transactions. It satisfies electric circuit laws and provides economic signals to users. Simulation results show that the proposed algorithm is effective and feasible.
