摘　　要：边际网损系数法由于能够反映各节点造成全网网损的微增成本信息,提供经济信号,已成为国外电力市场中最典型、最有应用前景的一种网损分摊方法。完全的边际网损系数法(FMLC)能提供最好的经济信号,但它不能保证所分摊的总网损与系统实际总网损一致,所以需要对该方法所分摊的网损量进行调整。本文应用比例法来调整网损分摊量。IEEE-14、IEEE-30和华东电网2243节点系统的算例表明:比例法合理地分摊了系统总网损,使之与实际总网损一致,并且,使用比例法后,保持了边际网损系数法的经济信号。The marginal loss coefficient method is one of the most typical and prospective methods to allocate the transmission loss in power market because it can reflect the incremental cost of system loss and can give the correct economic signal for investment. But its total loss by the full marginal loss coefficient method (FMLC) can not keep consistent with the actual loss, so it is necessary to regulate the calculated loss. This paper introduces a method named Scaling Method to regulate the total loss. The simulation on IEEE 14-bus, 30-bus system and a practical 2243-bus system shows that Scaling Method can allocate the loss reasonably and keep the loss consistent.Moreover,the economic signal of FMLC method is well kept by the scaling method.
