摘要(Abstract):
新电改的实施给现行的电网集中发电调度带来极大挑战,出现了电力交易和市场各方利益综合需求下的竞价与非竞价机组混合发电调度新难题。以云南和贵州电力市场改革为背景,从电网日前计划编制实际需求出发,兼顾购电经济性、节能降耗、竞价与非竞价机组调度公平性目标,考虑水电、火电及系统运行复杂约束,构建优化模型。提出中长期合约电量分解的二次规划方法,并以分解后的日电量为约束,保证竞价机组调度公平性;采用模糊优选法处理多目标模型,通过引入启发式策略,增加自适应参数,提高算法的稳定性和收敛性,实现模型高效求解。仿真测试表明,所提模型及方法在不同电源结构下均可获得合理调度结果,为过渡时期电力系统发电运行提供决策支持。
