摘　　要：为抑制微电网中新能源出力的波动并降低微电网的经济成本,通过引入混合储能设备来平抑新能源出力波动。构建了一种含混合储能的微电网能量管理模型,采用超级电容器和蓄电池组成混合储能设备,并设定风、光、混储、网、柴的依次供电顺序,采用Tent混沌映射、择优选择搜索空间和捕食位置以及Lévy飞行等改进策略对秃鹰搜索算法进行改进,提高算法的收敛速度和全局搜索能力,并运用于微电网综合成本优化求解。选取某地区4种典型日进行算例分析。结果表明:所提出的微电网容量优化配置模型、混合储能设备、供能策略和改进秃鹰搜索算法(bald eagle search algorithm,BES)算法能有效增强微电网平抑新能源出力波动的能力,降低微电网经济成本,并且改进的BES算法具备较强的收敛速度和求解能力。In order to suppress fluctuations in the output of new energy sources in the microgrid and reduce the economic cost of the microgrid,the introduction of hybrid energy storage equipment has been adopted to stabilize the fluctuations in the output of new energy sources.A microgrid capacity optimization configuration model was constructed with hybrid energy storage.The hybrid energy storage equipment was composed of super capacitor and battery,and the power supply sequence of wind,light,hybrid storage,network and diesel was set.The vulture search algorithm was improved by using improved strategies such as tent chaotic mapping,selective selection of search space and predator location,and Lévy flight to improve the convergence speed and global search ability of the algorithm,and it was used to solve the integrated cost optimization of microgrid.Four typical days in a certain area were selected for analysis.The results show that the microgrid capacity optimization configuration model,hybrid energy storage equipment,energy supply strategy and improved bald eagle search algorithm(BES)proposed can effectively enhance the microgrid’s ability to smooth the fluctuation of new energy output and reduce the economic cost of the microgrid,and the improved BES algorithm has strong convergence speed and solving ability.
