摘　　要：为实现含多微网系统的主动配电网的经济效益最优,通过引入自适应权重系数来进行动态优化。构建一种主动配电网层以发电机组运行成本最低,多微网系统层以经济成本和环境成本最低的分层能量优化管理模型。采用变异、杂交和竞争策略以及Lévy飞行策略改善麻雀搜索算法,提高算法的种群多样性和收敛精度。基于所设计的多微网系统混合配置运行策略,采用改进麻雀搜索算法进行模型求解。选取某地区两种典型日进行算例分析。结果表明:提出的优化模型、运行策略和改进算法可以有效降低主动配电网和多微网系统的经济效益,同时改进算法能够在全局寻优能力方面具有一定的优势。In order to achieve the optimal economic benefits of the active distribution network with multi-microgrid system,dynamic optimization was carried out by introducing adaptive weight coefficients.A hierarchical energy optimization management model was constructed,with the lowest operating cost of generating units at the active distribution network layer and the lowest economic cost and environmental cost at the multi-microgrid system layer.Mutation,hybridization,competition strategies and Lévy flight strategy were used to improve the sparrow search algorithm,which increase the algorithm's population diversity and convergence accuracy.Based on the designed multi-microgrid system mixed configuration operation strategy,an improved sparrow search algorithm was used to solve the model.Two typical days in a certain area were selected for analysis.The results show that the optimization model,operation strategy and improved algorithm proposed can effectively reduce the economic benefits of active distribution network and multi-microgrid system,and the improved algorithm has certain advantages in the global optimization capability.
