随着电力体制改革的不断推进,按照用户差异化需求制定可靠性电价成为完善电价体系的重要方面。文中综合考虑了系统运行方式和可中断响应因子,提出了基于改进长期增量成本法的配电网可靠性电价制定方法。该方法结合所提出的经济投资策略分析了不同运行方式下单位注入功率对经济投资年限的影响,根据不同运行方式下较小的经济投资年限推导了可靠性成本增量,并根据可靠性成本增量计算出不同可中断响应因子的区域可靠性电价。最后,计及用户差异化需求,基于单位可靠性增量成本制定了可靠性增量电价的定价方法。算例分析结果表明,由区域可靠性电价和增量电价相结合的定价体系能合理兼顾供电分区供电可靠性和用户差异化需求。
With the continuous pursuing of electric power system reform
reliability pricing based on the differentiated demand of users has become an important part of the improvement of the electricity price system. In this paper
a reliability pricing method of distribution network is proposed based on the improved long-run incremental cost method
which comprehensively considers the system operation modes and the interruptible response factor. Combined with the proposed economic investment strategy
the influence of the unit power injection on the economic investment horizon is analyzed in different operation modes with the proposed method
the incremental reliability costs are deduced according to the smaller investment horizon in the different operation modes
and the regional reliability price with different interruptible response factors is calculated according to the incremental reliability costs. Finally
considering the differentiated energy consumption demand of users
the formulation method of the incremental reliability price is developed based on the incremental reliability cost per unit. Case analysis results show that the pricing system based on the combination of regional reliability price and incremental price can reasonably take into account the power supply reliability of power supply zones and the differentiated demand of users.
