摘要

在区域电力现货市场中,通常用物理联络线通道的输电价格和传输电量的乘积计算省间输电电量费用,但该方法不能有效应对省间电力交易对应不同输电价格的情况.为此,首先分析省间电力交易对区域电力现货出清产生的影响,并提出对应的省间电力交易优化机制、省间电力交易网损处理机制、省间电力交易输电费用处理机制、省间电力交易与物理联络线通道潮流匹配方法、点对网电力交易匹配机制.以此为基础,结合区域电力现货出清标准化模型,提出考虑省间电力交易输电费用的区域电网现货出清定价模型,并推导出不同省级电网系统边际价格存在的数学关系.采用所提出清定价模型能够实现资源最优配置;同时,能有效激励市场主体合理竞价.最后,利用具体算例验证了所提模型的正确性和有效性.

Abstract

In the regional power spot market, inter-provincial transmission power costs are typically calculated by multiplying the transmission price of the physical tie-line channel by the transmission power. However, this method fails to effectively account for the inter-provincial power transactions at different transmission prices. To address this issue, this paper first analyzes the impact of inter-provincial power trading on regional power spot clearing. It then proposes an optinization mechanism for inter-provincial power trading network loss handling, transmission cost processing, tie-line channel flow matching, and point-to-network power trading alignment. Based on this, it proposes a regional power grid spot clearing and pricing model, which incorporates inter-provincial power trading transmission costs into a standardized regional power spot clearing model. It derives the mathematical relationship between the system marginal prices of different provincial power grids. The proposed clearing and pricing model aims to achieve optimal allocation of resources, while effectively stimulating market players to bid reasonably. Finally, it validates the correctness and effectiveness of the proposed model through specific numerical examples.

Key words： inter-provincial power trading; transmission costs; regional spot; clearing and pricing model
