为了进一步促进配电网内分布式电源和用电负荷的交互作用,在分布式算法的基础上提出了一种基于功率增量成本一致的源荷智能互动分布式协调优化控制方法。首先,构建了包含分布式控制的配电网分层通信架构,并以区域发电成本最优为目标提出了领导者节点和邻居节点控制策略;然后,建立各发电节点的功率增量成本模型,运用一致性算法实现了配电网内部功率的优化分配;最后,通过负荷突增和负荷投切两种不同场景的仿真分析,验证了所提协调控制方法能满足配网内源荷智能互动平衡,使整体经济利益最优。结果表明与对比方法相比,该文方法具有更快的迭代更新速度和更好的经济以及动态控制性能。

In order to better promote the interaction between distributed generation and power load in power distribution network,based on the distributed algorithm,this paper proposes a source-load intelligent interactive distributed coordinated optimal control method based on the incremental power cost consistency.First,this paper constructs a distribution network layered communication architecture including distributed control and aiming at the optimization of regional power generation cost,the control strategy of leader node and neighbor node is proposed.Then,the power incremental cost model of each generation node is established,and the optimal internal power allocation in power distribution network is realized by power incremental cost consistency algorithm.Finally,through the simulation analysis of two different scenarios of sudden load increase and load switching,it is further verified that the proposed coordinated control method can meet the interactive balance of internal source-load intelligence in power distribution network and optimize the overall economic benefits.The results show that compared with the comparison method,this method has faster iterative update speed,better economy and dynamic control performances.
