Multi-objective Dispatching of Regional Integrated Energy System Considering the Integrated Demand Response

随着传统能源枯竭,为提高供能经济性和效率,区域综合能源系统应运而生,区域综合能源系统的优化调度成为关键问题。由于多种能源之间存在耦合,多种能源的综合需求响应为区域综合能源系统的优化调度提供新的手段。因此,首先分析了区域综合能源用户的多种能源需求侧响应函数,进而构建了以经济性和能效为目标的区域综合能源系统多目标优化调度模型,最后提出改进的带精英策略的非支配排序的遗传算法用于求解多目标优化问题。通过算例验证了该模型可有效解决区域综合能源系统的多目标优化调度问题,综合需求响应可以有效提升区域综合能源系统的经济性和能效水平。

With the depletion of traditional energy sources,the regional integrated energy system(RIES)came into being to increase the economic and efficiency of energy supply.The optimal dispatching of RIES is the key issue.Due to the coupling of multiple energy sources,the integrated demand response of RIES users provided a new way for the optimal scheduling of RIES.The integrated demand response function of regional comprehensive energy users was analyzed,and then the multi-objective optimization scheduling model of RIES was constructed aiming at the economy and energy efficiency of RIES.An improved non-dominated scheduling genetic algorithm with elite strategy(NSGA-II)was proposed to solve the multi-objective optimization problem.Results show that the model can effectively solve the multi-objective optimization scheduling problem of RIES,and the integrated demand response can effectively improve the economic and efficiency level of RIES.
