摘　　要：针对电力市场中市场成员公平、合理地分摊电网损耗的问题,对电网损耗分摊方法进行了研究,根据博弈论中的Shapley公理和Shapley值的理论,推导出电网耗散功率转归分量的解析式,并结合潮流追踪理论,提出了一种基于耗散功率转归分量和潮流追踪相结合的损耗分摊新方法。先利用支路耗散功率转归分量理论,将所有支路的耗散功率转归给等值电网中的节点电流源,再运用潮流追踪理论,将转归给节点电流源的损耗功率分摊给实际电网中的所有交易成员,最后利用IEEE4节点系统对该方法进行了仿真计算。研究结果表明,该方法不仅满足电路定律、并计及有功和无功潮流的交叉耦合,使电网中所有电源和负荷都参与了损耗分摊,具有公平、合理、易于实现的特性。Aiming at the fair and reasonable apportionment of power loss problem to members in electricity market,the method of power loss allocation was researched. A new loss allocation method based on the theory of power flow tracing and imputation components of dissipation power was proposed,based on the Shapley axiom and Shapley value theory in game theory and the rigorous mathematical derivation. The imputation part of branch dissipation power to each current source node can be calculated by the theory of imputation components of dissipation power. And then,the loss of current source node was allocated to all members in actual power grid by using the theory of power flow tracing.Finally,the method was simulated in IEEE 4-bus system. The results indicate that the proposed method is demonstrated by the circuit laws,the interactions between active and reactive powers is also considered,and all the network losses could be allocated to all consumers and generators,which make power loss allocation fair and reasonable.
