There are problems of complex power quality disturbance types and rapid changes caused by the organic combination of photovoltaic power generation and electric vehicle fast charging station while at the same time giving full play to the advantages of clean energy and greatly improving charging efficiency. Thus a power quality integrated control method for a new power quality compensator based on a ‘series parallel combined’ distribution flexible AC transmission system (DFACTS) is proposed. The main circuit topology of the new power quality compensator is studied and the dynamic working model is established. The working principle of the linear active disturbance rejection control method of the new power quality compensator is analyzed in detail, and a linear active disturbance rejection controller is designed. Given the interaction between DFACTS controllers, a coordinated control strategy of multiple DFACTS controllers is proposed. Finally, a simulation model is built for verification. The results show that the proposed new power quality compensator improves the comprehensive compensation ability and dynamic response ability of the rapid change of power quality disturbance with the help of a linear auto disturbance rejection control method. It compares well with the traditional PI control method. It is verified that the coordinated control can effectively improve the voltage stability of the system, and has good feasibility and effectiveness.
