本文通过将配电网视为耦合微电网，重点研究配电网管理系统的分散式最优控制算法。基于单个微电网的自主控制模型，利用不同微电网之间的协调信息和策略来降低分布式发电的运行成本，提高分布式储能的利用效率，并降低配电网运行的复杂性。将微电网的最优控制问题建模为分散式部分可观测马尔可夫决策过程（DEC - POMDP），并通过引入一种前瞻对偶乘子机制作为来自集中式信息的分散控制信号，采用一种协调动态规划算法来解决该问题。本文最后通过一些研究案例讨论了该算法的性能以及不同协调信息的影响。
This paper focuses on the decentralized optimal control algorithm for distribution management system by considering distribution network as coupled microgrids. Based on the autonomous control model of each single microgrid, coordinated information and strategies among different microgrids are used to decrease the operating cost of distributed generation, improve the efficiency of the distributed storages utilization, and reduce the complexity of distribution network operation. The optimal control problem of microgrids is modeled as a decentralized partially-observable Markov decision process (DEC-POMDP), and a coordinated dynamic programming algorithm is used to solve the problem by introducing a look-head dual multiplier mechanism as decentralized control signals from centralized information. The performances of this algorithm and the impacts of different coordinated information are discussed by some study cases in the end of this paper.
