一种基于改进NSGA-II算法的电-气-热综合系统多目标优化方法
摘要：
本发明公开一种基于改进NSGA-II算法的电-气-热综合系统多目标优化方法，该方法为：(1)以能量系统约束、天然气系统约束和热力系统约束作为约束条件，以成本最低和碳排放最少作为两个目标函数，建立电-热-气综合能源系统的多目标优化调度模型；(2)采用全局的帕累托集维护方法对NSGA-II算法进行改进，改进后的NSGA-II算法对步骤(1)获得的多目标优化调度模型进行求解。本发明采用维数降低和动态调整的方法提高在高维等式约束下找到可行解的概率。对于电-气-热综合系统的经济调度和环境保护都有十分重要的意义。
摘要（英）：

The invention discloses a multi-objective optimization method for an electricity-gas-heat comprehensive system based on an improved NSGA-II algorithm. The method comprises the following steps: (1) establishing a multi-objective optimization scheduling model of an electricity-heat-gas comprehensive energy system by taking energy system constraints, natural gas system constraints and thermodynamic system constraints as constraint conditions and taking lowest cost and least carbon emission as two objective functions; and (2) improving an NSGA-II algorithm by means of a global Pareto set maintenance method, and the improved NSGA-II algorithm is adopted to solve the multi-objective optimization scheduling model obtained in the step (1). According to the method, the probability of finding a feasible solution under the constraint of a high-dimensional equation is improved by adopting a dimensionality reduction and dynamic adjustment method. And the method has very important significance for economic dispatching and environmental protection of an electricity-gas-heat comprehensive system.
