摘　　要：结合目前我国节能降碳发展目标,针对计及阀点效应的经济调度问题求解方法开展研究。首先,从求解经济调度函数模型的传统数学方法和遗传优化算法的局限性进行研究,然后提出了一种改进差分进化算法,通过引入混沌初始化操作,制定了一种非线性动态调整控制参数策略。最后,通过算例仿真对所提出的方法进行验证,结果表明本文所提出的改进算法与其他计算方法相比,在结果精度和鲁棒性等方面更具优势。Combined with current development goal of energy conservation and carbon reduction in China, the method of economic dispatching problem with valve-point effects is studied in this paper.Firstly, limitations of traditional mathematical methods and genetic optimization algorithms for solving economic dispatch function models are studied.
