主动配电网中联络变压器和无功补偿装置的多代理控制方法

Multi-Agent Control Method for Interconnecting Transformer and Reactive Power Compensation Device in Active Distribution Network

为了协调控制主动配电网中联络变压器与无功补偿装置,建立了基于多代理技术的全局协调控制模型。多代理技术凭借其灵活的结构和代理自治性,能够较好地将集中式控制与分布式控制结合在一起,建立的区域主导节点决策模型,能够实现电压越限区域电压薄弱节点的动态跟踪。将合同网通信协议和调压优先原则相结合,通过对无功-电压灵敏度指标的竞争,能够实现联络变压器和区域无功补偿元件补偿量计算的时序优化。最后在IEEE33配电系统中进行了仿真,仿真结果表明多代理技术能够协调联络变压器与无功补偿装置进行电压调节。

For the coordinate control of interconnecting transformer and reactive pow er compensation device in active distributed network,this paper proposed a global coordinated control model based on multi-agent technology. Multi-agent technology with its flexible structure and agent autonomy could combine the centralized control with the distributed control better; and realize the dynamic tracking of weak-voltage node in voltage over-limit area through building the regional leading agent decision model. By combining CNP（ contract net protocol） and voltage regulation priority principle,it could achieve the timing optimization for the compensation amount calculation of interconnecting transformer and regional reactive power compensation elements,through the competition of reactive pow er-voltage sensitivity index. Finally,this paper carried on the simulation in IEEE33 distribution system,whose results showed that the multi-agent technology could realize the voltage regulation by combine interconnecting transformer with reactive power compensation device.
