摘要/Abstract

摘要： 针对目前动态经济调度研究中风电波动性和不确定性引发旋转备用响应风险难以有机考虑的问题,提出一种针对高风电接入比例下的动态经济调度方法。将机组强迫停运引发的旋转备用响应风险有机统一到时间耦合引起的响应风险中,将旋转备用响应风险的用户停电损失期望和弃风损失期望加入目标函数中,在寻求目标函数最小的同时,自动为系统配置适宜备用,保证各时段系统响应风险的一致性。利用改进的多宇宙并行量子遗传算法以及图形处理器(graphics processing unit, GPU)加速技术对模型进行求解。10机系统算例及其分析证明了该方法的有效性和可行性,能够在动态经济调度中准确度量风电波动性和不确定性共同引发的旋转备用响应风险。
