摘　　要：针对微电网中多个分布式电源的优化调度问题,提出一种基于有限步收敛一致性的完全分布式优化调度算法。该算法无需控制中心,仅需各相邻分布式电源之间的局部信息交互迭代收敛到最优值。同时,由于采用了有限步收敛离散一致性算法和固定步长反馈增益,该算法的收敛速度大幅加快。最后,在IEEE-14节点系统中测试算例仿真,验证了所提分布式调度算法的性能和可扩展性。A fully distributed economic dispatch algorithm based on finite step convergence consensus is proposed for the optimization dispatch problem of multiple distributed generations in microgrids.This algorithm does not require a control center and only requires local information exchange between adjacent distributed generations to iteratively converge to the optimal value.Meanwhile,due to the use of finite step convergence discrete consensus algorithm and fixed step feedback gain,the convergence speed of this algorithm is significantly accelerated.Finally,the performance and scalability of the proposed distributed dispatch algorithm were verified through testing and simulation in an IEEE-14 node system.
