摘要
电力系统调度是在满足系统安全约束的前提下,通过优化发电机组出力,提高经济性。风电固有的不确定性在大量风电场的接入后对电力系统的稳定运行提出了新的难题。本文将鲁棒优化思想于含风电的不确定性电力系统调度问题,以不确定性集合处理风电出力的不确定性。同时目标函数中考虑由于阈点效应而产生的额外损耗。最后结合修改的IEEE-14节点算例证明所提算法有效应对风电不确定性对调度的影响。
Under the precondition of satisfying the system security constraints, the power system dispatch is optimized to improve the economic performance. A method based on robust optimization is proposed to deal with the uncertainty of wind power. The energy cost of the threshold effect of conventional thermal power units is considered in the objective function. Combining with IEEE-14 node example, proves that the proposed algorithm can effectively deal with the influence of wind power uncertainty on scheduling.
