基于改进NSGA-Ⅱ算法的电-气-热综合能源系统多目标优化
摘要：随着电力、天然气和热力网络耦合紧密程度不断加深，综合能源系统协同优化成为了新的研究热点。提出一种适用于含非凸约束条件的综合能源系统多目标优化问题的改进NSGA-Ⅱ算法，通过维护全局的帕累托最优解集提升解的搜索效率，同时采用动态调整法，提高在高维等式约束下找到可行解的概率。算例分析验证了该方法的有效性。
Abstract:With the development of interaction between electricity, natural gas and heat networks, collaborative optimization of integrated energy system has become a new research focus. An improved NSGA-Ⅱ algorithm was proposed to solve the optimization problem of integrated energy system, which contained multiple objectives and nonconvex constraints, a global Pareto set maintenance method was proposed to improve the search efficiency of Pareto-optimal solutions. Dimensional reduction and dynamic adjustment were applied to improve the probability of finding feasible solutions under high-dimension equality constraints. An example was analyzed to prove the validity of the proposed method.
