摘要:
      柔性多状态开关(FMSS)作为一种新型电力电子装置能够部分替代配电网中传统联络开关,实现潮流的不间断灵活调控,优化电压分布。探讨了三端FMSS在配电网中的几种可能接入拓扑及工作模式,建立了三端FMSS的动态数学模型,结合三端控制约束提出了三端FMSS模型预测协同控制策略。该策略具有原理清晰、实现简单、动态响应速度快等优点,避免了传统比例-积分(PI)双闭环控制策略存在的控制结构复杂、PI参数较多且整定困难的问题。基于模型预测控制对各端口UdcQ控制模式、PQ控制模式,以及Uacf控制模式进行了具体算法实现。为了验证所提方案的有效性,在MATLAB/Simulink环境下搭建了三端FMSS仿真模型,不同工况下的仿真结果验证了所提三端FMSS模型预测协同控制策略能够有效实现多端口间的协同控制,发挥FMSS的调节功能,为FMSS的配电网应用提供灵活的解决方案。
Abstract:
      As a new type of power electronic device, flexible multi-state switch(FMSS)can partly replace the traditional tie switch in the distribution network to realize uninterrupted flexible regulation of power flow and optimize voltage profile. Several possible topologies and working modes of the three-port FMSS in the distribution network are discussed. The dynamic mathematical model of three-port FMSS is established and a three-port FMSS coordination control strategy based on finite-control-set model predictive control(FCS-MPC)is proposed, which has many advantages of clear principle, simple implementation and fast dynamic response. It avoids the problems of traditional propontional-integral(PI)double closed-loop control strategy including complex control structure, more PI parameters and difficult setting. Based on FCS-MPC, the control algorithms of UdcQ mode, PQ mode and Uacf mode are implemented. Accordingly, the coordination control strategy between the modes of three ports is presented. In order to verify the feasibility of the proposed scheme, a three-port FMSS simulation model is built by using MATLAB/Simulink. Simulation results show that the proposed coordination control strategy can effectively achieve multi-port coordinated control and adjustment function which can provide a flexible solution for the applications of multi-port FMSS.
