摘　　要：节点边际电价因具有丰富的经济学含义而在电力市场中得到了广泛应用。节点边际价格的实施必将会带来市场销售盈余,而销售盈余的处理一直存在争议。分析了销售盈余产生的原因,以耗散功率分配法为基础,结合实际潮流,提出了一种无销售盈余的节点电价制定方法,从根本上消除了销售盈余。IEEE9节点算例仿真结果表明,该方法不仅明确了电价中的损耗分量、计算简便,而且能够消除销售盈余,确保全系统收支平衡。Due to its rich economic information, the nodal marginal price is widely applied in electricity market and the implementation of locational marginal price will surely bring marketing surplus, however there is controversy on its management. In this paper, firstly the cause engendering the marketing surplus is analyzed; then based on the allocation of dissipation power and combining with actual load flow, a method to draft nodal price without marketing surplus is proposed, thus the marketing surplus is eliminated by the root. Simulation results of IEEE 9-bus system show that the proposed method not only can make the loss component in the electricity price explicit, and its calculation is convenient, but also the marketing surplus can be eliminated, therefore the balance of income and outlay of the whole power grid can be ensured.
