摘要:
为提高电网调度运行的精益化管理水平,美国PJM电力市场于2007年提出了理想调度评估方法。与传统的电网运行评估方法相比,理想调度从后评估的角度,通过“反演”计算电网调度运行中的最理想方案,以量化评估实际运行情况与理想方案之间的差距。本文将理想调度与实际的业务过程相结合,全面辨识影响电网运行效益调度程度的各类因素。通过引入信息还原等评估理念,基于对电网运行全过程记录,本文提出了过程化的理想调度评估方法,实现了对调度员决策水平的评估分析及各类外部因素影响程度的量化计算,为进一步提高电网调度运行的精益化水平提供了科学的手段与工具。最后,以实际电网的运行数据构造算例,验证了本文所提出方法的合理性与有效性。

Abstract: In order to enhance the management level of power system operation, PJM power market operator proposed the Perfect Dispatch Evaluation Method (PDEM) in 2007. Compared to the traditional evaluation methods, PDEM incorporated the actual operation boundaries and determined a virtual “Perfect Dispatch Scheme” (PDS) from post hoc perspectives. In this case, the deviations between the actual situation and the PDS could be quantitatively analyzed. This paper further implemented the PDS into various process of power system operation, identified the critical influencing factors, and formulated the influencing mechanisms. Based on information restoration and process analysis techniques, a novel PDEM is proposed to identify the effects incurred by decision and non-decision factors, respectively. In the end, a numerical case based on real operation data is studied to testify the effectiveness of the proposed method.
