Research on a New Topology and Coordinated Control Strategy of Multi-Station Integrated System
2021
With the rapid development of distributed power and new energy vehicles, the traditional distribution network is facing enormous challenges. The development of multi-station integration technology is an effective way to solve the above problems. In this paper, a new multi-station integration topology is proposed. The new multi-station integration topology uses soft open point (SOP) as the key equipment of the system, and adopts the hierarchical power supply mode for data center, electric vehicle charging pile and other function stations. Then, based on the new topology of multi-station integration and smooth switching of converter control mode, a coordinated control strategy is proposed. Through the coordinated control strategy to control the working mode of each function station, and then further optimize the system operation conditions. Based on Matlab/Simulink, the simulation model of multi-station integration is established, and two different application scenarios are analyzed. The simulation results verify that the new topology of multi-station integration and its coordinated control strategy effectively improve the voltage level of the distribution network, improves the reliability of sensitive load power supply, and ensure the safe and reliable operation of multi-station integration system.
