摘　　要：与大用户直购电相关的如何确定其应该承担的电力网络固定成本这一个重要问题,仍未得到很好解决。在此背景下,对大用户直购电交易所需分摊的电力网络固定成本进行了系统分析,并考虑了交易的多方面属性。首先从用户侧、发电侧和电网环节3个方面构建了与直购电交易相关的电力网络固定成本分摊的指标体系;之后,在数据包络分析框架下建立了联盟博弈模型,并利用区间层次分析法在该模型中引入了反映决策者偏好的权重约束,进而获得了一种能够计及指标权重约束的电力网络固定成本分摊模型;最后,以IEEE14节点系统为例说明了所提方法的基本特征。算例结果表明,这种方法能够在满足决策者偏好的前提下保证分摊结果的公平合理。How to allocate power network fixed cost is an important but not yet well-solved issue related to direct trades between large consumers and generation companies. Given this background, this issue is systematically analyzed considering various attributes of direct trades. Specifically, an evaluation system for allocating power network fixed cost is structured first from three aspects ： the user side, generator side and the impacts on the power system. Then, a cooperative game model in the framework of data envelopment analysis is presented to address this issue. In this model, weight constraints are introduced by employing the interval analytic hierarchy process （IAHP） to reflect the preference of decision-makers, and a power network fixed cost allocation model considering the index weight constraints is next attained. Finally, the IEEE 14-bus system is employed to demonstrate the basic characteristics of the developed model. Simulation results showed that the proposed approach can lead to fair and reasonable allocations with decision makers＇ preference considered.
