摘　　要：针对联营-双边混合交易模式的特点,基于"论责分摊"的思想,提出了一种基于潮流追踪计算阻塞影响因子的方法。根据该方法可将阻塞线路上的阻塞费用根据交易参与者定量阻塞责任的大小进行分摊。即首先利用约束分配系数将系统阻塞费用分摊给阻塞所在线路,然后利用潮流追踪法得出各个市场成员对阻塞线路的利用份额,最后将线路阻塞费用分配给所有市场成员。该方法不产生销售盈余,给市场参与者提供了准确的经济信息。IEEE-14节点系统算例结果显示,该方法能够正确有效地分摊市场成员的阻塞费用。In view of mixed pool and bilateral markets, a new method based on liability is proposed to allocate the congestion cost among consumers and providers by power flow tracing theory. Each marketing participator pays for the congestion costs in proportion to its liability. In this method, firstly according to constraint allocation factor the congestion cost of power system is allocated to congested lines. Then using power flow tracing, the each market participant＇s utilization degree of congested lines are calculated. Finally, the congestion is allocated to all market participants. The proposed method eliminates the merchandising surplus, it provides correct economic signals to all the partners of power system. Calculation result of a IEEE-14 test system show that proposed method can allocate congestion cost among market participants correctly and effectively.
