电力市场联营-双边交易模式下的阻塞费用分摊

针对联营-双边交易模式电力市场的特点和我国处于电力市场改革初期的具体情况,提出了一种新的阻塞费用分摊方法,即首先按照约束分配系数将系统阻塞费用分摊到阻塞线路,然后利用潮流追踪方法得出各市场成员对阻塞线路的利用程度,最后将线路阻塞费用分摊给全部市场成员。5节点系统算例结果表明,该方法能够正确有效地分摊市场成员的阻塞费用。

Congestion Cost Allocation under Pool-Bilateral Transaction Mode

In view of pool-bilateral transaction mode in electricity market and considering that the reform of electric power industry in China is still in initial stage and the trading volume of bilateral transaction is smaller,a new method to allocate the congestion cost among lateral transaction and pool users is proposed.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 cost is allocated to all market participants.Calculation results of a 5-bus system show that the proposed method can allocate congestion cost among market participants correctly and effectively.
