摘要(Abstract):
伴随电力市场开放程度与日俱增,发电企业在调度出力中将拥有更大的决策权。因此,立足于兼顾电网与多种类型发电厂利益构建的调度模型显得极为必要。将电网作为博弈主体,在保证电力供求平衡的基础上,以其购电成本与环境成本最小化为优化目标;将风、水、天然气电厂作为3个参与电力市场博弈的独立从体,在综合考虑各类电厂出力特性的基础上,以3个参与者的收益最大化作为优化目标;将电厂出力策略以及电网优化的上网电价作为决策空间,构建了基于一主三从博弈理论的区域电力系统调度模型,并提出了基于NSGA-II求解该模型Stackelberg-Nash均衡解的算法。算例仿真表明,所建立的一主三从博弈区域电力系统调度模型能够适应不同季节下的区域系统调度,并显著提高了调度控制中各电厂间利益分配的均衡度与稳定程度。
