摘要
交直流混合配电网的运行模式和协调控制方法是保证其高效可靠运行需要解决的关键技术之一。针对这一问题,提出了一种交直流混合配电网的协调控制方法,详细分析了交直流混合配电网在正常运行和交流侧短路故障情况下的运行模式,给出了不同运行模式下互联装置、储能系统和光伏发电单元的控制框图。最后通过Matlab/Simulink仿真软件进行了仿真研究,仿真结果验证了所提出控制策略的可行性和有效性。
Operation mode and coordinated control method of AC/DC hybrid power distribution network is one of the key technologies to ensure its efficient and reliable operation. To solve this problem, the paper proposes a coordinated control method for AC/DC distribution network. The operation mode of normal operation and AC-side short circuit fault are analyzed in detail, the control diagram of interlink converter, energy storage system and photovoltaic power generation unit are given for different operation modes. Finally, the simulation research is carried out by Matlab/Simulink simulation software, the feasibility and effectiveness of proposed control method is verified by simulation results.
