能源送出省输配电价定价方法探讨
|
摘要
电力市场化改革的推进,亟需研究适用于电能送端省级电网输配电价定价方法。在总结已有输配电成本分摊和定价方法适用性基础上,分析了电能送出省特征及其对输配电服务定价的影响;然后提出3种输配电服务成本分摊定价方法。分析结果表明,在输电环节采用潮流追踪法可最大限度区分省内/外网络用户对输电网的使用程度,在配电环节采用分电压等级邮票法,兼顾了能源送出省负荷密度低、负荷需求小、经济承受能力差的特点。
With the advancement of electricity market reform, the pricing method for transmission and distribution tariffs suitable for province exporting power needs to be studied. Based on existing transmission-distribution pricing methods, the characteristics of province exporting power are summarized, and its impact on the pricing are pointed out. Three transmission and distribution services cost-sharing pricing methods are proposed. The results show that the power flow tracing method in the transmission can distinguish internal and external network users, and the voltage classification stamp method in the distribution can take the characteristics of low ene rgy density, low load demand, and poor economic affordability into account.
