消除基于实时电价理论电力市场中交易盈余的一种新方法——追踪加权平均法

A NEW APPROACH OF ELIMINATING MERCHANDISE SURPLUS DUE TO SPOT PRICING OF ELECTRICITY—TRACING AND WEIGHTED AVERAGE METHOD

分析了电力市场中与交易盈余有关的问题 ,提出了一种新的定价方法——追踪加权平均法 ,它无需改变发电机的优化电价 ,而是使用户承担的电价等于各节点优化电价的加权平均 ,其权重在理论上等于该节点发电机向特定负荷供电的比率。该方法基于最新提出的电能追踪理论 ,它消除了交易盈余以及与之有关的许多问题。最后用 CIGRE10节点网络验证了该方法的可行性。

In this paper the problems associated with the merchandise surplus in electricity market is analyzed. A novel approach of pricing is put forward which does not alter the selling price but makes the buying price equal to the weighted average of the nodal optimal prices, its weight is theoretically equal to the ratio of powersupplied to aspecified load from individual power plant. Based on a recently proposed electricity tracing theory, this pricing method eliminates the merchandise surplus and associated problems. The feasibility of this method is validated by an example of 10 node CIGRE network.
