摘要
在电力现货市场中,为保障具有充足的调度资源应对实时运行场景变化,系统运营商仍需在日前市场出清的基础上进行场外调整.场外调整将缓解日前市场出清模型与实际系统运行边界间的差异性,确保电网的安全可靠运行.然而,由于场外调整并非市场环节,引入非市场化调整将影响电力现货市场的整体运行效率.因此,场外调整对现货市场的影响需要进一步分析.该文介绍国外典型的市场流程和场外调整,探讨场外调整的成因.通过算例的调度结果对比,从市场剩余变化和市场运行成本两方面量化评估场外调整的市场影响.该文希望通过研究国外的市场流程与场外调整方法,为我国电力现货市场中的非市场资源配置行为建模及改善提供研究思路.
Abstract
To ensure sufficient resources for the operating day,the system operators still execute out-of-market corrections(OMCs)after the day-ahead market.At present,the OMCs cope with the difference between the day-ahead market and the operational boundaries,which guarantees safe and reliable scheduling results.However,since the OMCs are not a market process,the non-market adjustments affect the efficiency of the electricity spot market.Therefore,the impact of OMCs on the spot market needs further analysis.This paper introduces the market frameworks and the OMC processes in typical countries,and provides the cause analysis of OMCs.Through the numerical results,the market impact of OMCs undergoes quantitative assessment from the aspects of market surplus and market operating cost.By studying typical market frameworks in foreign countries,this paper aims to provide a reference for modeling non-market allocation and improving market efficiency in China's electricity spot market.
