含分布式电源及电动汽车的多代理配电网重构

Reconfiguration of Distribution Network with Distributed Generations and Electric Vehicles Using Multi-agent

为缓解分布式电源和电动汽车的接入对配电网电能质量和网络损耗的影响,并谋求配电网重构时电能质量和网络损耗的最优控制,本文提出一种基于JADE开发平台下的多代理控制系统,在配电网重构过程中充分考虑分布式电源和电动汽车对配电网潮流影响。在改进的IEEE-33节点系统中进行了仿真分析。仿真结果与传统局部控制策略相比较,既有效解决了馈线过载和电压越限问题,又优化了配电网电能质量和网络损耗,并具有更强的鲁棒性和可靠性。

In order to alleviate the influence of the access of distributed generations and electric vehicles on the powerquality and network loss of distribution network,and to seek the optimal control of power quality and network loss in thereconfiguration of distribution network,a multi-agent control system is proposed based on JADE development platformin this paper,which fully considers the impact of distributed generations and electric vehicles on the power flow there-in. Simulation analysis is carried out in a modified IEEE 33-node system. Compared with the traditional local controlstrategy,the multi-agent control system is more effective in solving the problems such as feeders' congestion and over-limit voltage. Moreover,it optimizes the power quality and network loss,showing stronger robustness and reliability.
