    Distributed Optimal Power Flow Analysis of Partitioned Micro-grid Based Multi-agent

    • 摘要: 提出了一种基于多代理技术的微电网分区分布式协调解决控制策略。结合潮流计算和经济调度问题,构建了最优潮流模型。考虑区域之间的平衡,将复杂的电力系统网络进行分区,区域之间通过区域控制误差(ACE)来补偿频率的偏差值。设置两级Agent(母线Agent和区域Agent)进行分层的优化调度以求解最优潮流问题,得到最优的微电网潮流分布,实现微电网安全、稳定和经济最优运行的目标。利用多代理技术完成微电网最优潮流分析,分布式有利于保护各区域电网的内部信息安全,解决了集中式优化存在的通信量过大的问题。

       

      Abstract: In this paper, a distributed coordination control strategy based on multi-agent technology is proposed for the partitioned micro-grids. By comprehensive considering the power flow calculation and economic scheduling problems, we construct the optimal power flow model. The complex power network is partitioned to achieve the balance among different regions. Meanwhile, the regional control error (ACE) is used to compensate the frequency deviation of different areas. Moreover, the optimal micro-grid power flow problem is solved by optimizing the hierarchical scheduling with two-level agents, i.e. bus agent and regional agent. The optimal power flow distribution of micro-grid is derived to achieve the objective of safety, stability, and economy optimal operation. Finally, it is shown via experimental results that the multi-agent technology can effectively analyze the optimal power flow of the micro-grid and the proposed distributed method can protect the internal information security of each regional power grid and cope with the problem of excessive communication in the centralized optimization.
