摘　　要：作为清洁可再生能源,水电具有显著环境效益。发展水电微电网,是实现“双碳”目标的重要路径之一。基于分布式水电出力特性提出多分布式水电协调运行策略以及基于此策略的微电网重构方法及模型。为避免寻优过程中产生大量不可行解,提出基于改进粒子群算法的微电网重构求解算法。选取IEEE 33节点系统进行算例仿真,验证了所提方法的合理性和有效性,能够有效提升微电网运行经济性。As a clean and renewable energy source,hydropower has significant environmental benefits.The development of hydropower microgrids is one of the important paths to achieve the"double carbon"goal.Based on the output characteristics of distributed hydropower,a coordinated operation strategy multi-distributed hydropower is proposed,and a microgrid reconfiguration method and model based on this strategy is put forward.In order to avoid a large number of infeasible solutions in the optimization process,a microgrid reconfiguration algorithm based on improved particle swarm optimization is proposed.The IEEE 33-node system is selected to simulate an example,which verifies the rationality and effectiveness of the proposed method,which can ef⁃fectively improve the operation economy of the microgrid.
