摘要/Abstract

摘要： 针对机组组合中如何实现机组有功出力与备用容量协调调度的问题,建立了考虑机组投运风险的机组组合模型。讨论了考虑风电接入时模型的处理方法。采用基于条件期望值的求解方法,不仅能够控制系统的失负荷概率,还能在一定程度上限制失负荷事件的后果。通过仿真算例证实了其方法的显著优势,对电力系统机组组合优化调度问题有一定实用价值。

Abstract: This paper aimed at the coordinated dispatching problem of generation and operating reserve. A dispatching model considering unit commitment risk was built. Calculation method based on the conditional expectation was proposed to control both the probability and degree of load lost accident. The approaches to deal with wind power integration and dispatching energy storage load were discussed. Simulation test proves the simpleness, correctness and feasibility of the above method by comparison with other method introduce in our references. The results show that the method can also solve the physical index which stands for the shortage of available generation capacity. And it has the obvious advantage of calculation speed which makes it of great practical value in power systems unit commitment problem.

Key words: unit commitment, unit commitment risk, coordinated dispatch, conditional expectation
