摘要: 输电网固定成本分摊是输电定价最重要的环节之一,其分摊方法直接关系到输电定价结果的合理性。针对跨区高压输电网固定成本特点,提出了一种考虑分时潮流追踪和峰荷责任的输电固定成本分摊方法;以潮流追踪为基础,分别确定负荷各时刻对线路的功率分配,并以追踪所得各负荷对每一输电元件时段内最大功率分配为依据,从而确定各负荷对系统不同时段的成本分摊;用IEEE30节点算例系统对提出的方法进行验证,表明所提出方法能够更准确合理地反映负荷对输电固定成本的使用情况。

Abstract: Allocation of transmission grid’s fixed cost is one of the most important processes in the tariff setting, which is directly related to the rationality and justification of the pricing policy. According to the characteristics of high voltage transmission grid’s fixed cost, an allocation method of transmission grid’s fixed cost is proposed in this paper by considering the timely flow tracing and peak load responsibility. Based on the flow tracing, the maximum usage ratio of each line is calculated for peak and valley period, which forms the basis of transmission fixed cost allocation. The method follows the ideal of peak load responsibility. Meanwhile, the peak-valley price mechanism is reflected in the transmission link. The rationality of the method is verified by using IEEE30-bus system. Compared with the traditional flow tracing method, the proposed method is more reasonable in reflecting the usage of the transmission fixed cost by load.

Key words: fixed cost allocation, flow tracing, peak load responsibility, time-sharing electricity price
