摘　　要：为进一步构建清洁低碳、经济节能的供能系统,研究建立了含风、光以及多元储能的分布式能源系统,针对北京某办公园区,采用DeST预测用户负荷以及当地风、光条件。以经济性、节能性和环保性三方面的综合效益最大为目标,提出一种自适应优化运行策略,分别采用穷举搜索法和遗传算法对系统优化调度方案进行优化。同时,采用以电定热运行策略作为对照,对比分析几种不同运行策略下系统的综合效益。结果表明:传统以电定热运行模式下的综合效益平均值为0.41;而在自适应优化运行策略下,使用遗传算法得到的调度方案,其综合效益平均值可达0.5,穷举搜索法得到的运行方案,其综合效益平均值可达0.51。In order to further build a clean,low-carbon,economical and energy-saving energy supply system,a distributed energy system with wind,solar and multi-energy storage was established.For an office park in Beijing,DeST simulation software was used to predict user load and local wind and solar conditions.An adaptive optimal operation strategy was proposed to maximize the comprehensive benefits of economy,energy-saving and environmental protection.The exhaustive search method and genetic algorithm were used to optimize the optimal scheduling scheme of the system.Meanwhile,using the electric heating operation strategy as a comparison,the comprehensive benefits of the system under several different operation strategies were compared and analyzed.Results show that the average comprehensive benefit under the traditional following electrical load operation mode is 0.41 on average;under the adaptive optimization operation strategy,the average comprehensive benefit of the scheduling scheme obtained by genetic algorithm can reach 0.5,and the average comprehensive benefit of the operation scheme obtained by the exhaustive search method can reach 0.51.
