摘　　要：在电力工业放松管制的环境下,输电扩展规划问题将会变得更为复杂。作者引入了帕累托最优、帕累托改进和社会福利等经济学概念,试图从根本上探索市场环境下输电扩展规划所应遵循的经济准则。基于帕累托改进的准则,提出了一种输电扩展模型。该模型涉及电力市场机制和输电成本分摊方案等因素。在节点边际定价的市场机制下,提出了三个简单的输电成本分摊方案。为了展示所建模型及所提出的输电成本分摊方案的内涵和特点,对一个六节点系统算例进行了详尽的分析。In the deregulated power industry environment, the transmission expansion issue becomes more complicated. Here, the economics concepts including Pareto optimality, Pareto improvement and social welfare are introduced for seeking the economic rules that should be followed in the transmission expansion thoroughly. Based on the Pareto improvement criterion, the authors propose a generalized model of transmission expansion. In this model, the factors such as the electricity market mechanism and the transmission cost allocation are also involved. Under the market mechanism of locational marginal pricing (LMP), three simple allocation arrangements of transmission cost are presented. Further, to illustrate the implications and the characters of the proposed model and the transmission cost allocation arrangements, a 6-node system study case is analyzed in detail.
