AC/DC Hybrid Renewable Energy System Coordinated Control and Test Platform

Abstract

AC/DC hybrid power distribution can achieve high-efficiency consumption and high-proportion access of new energy, and provide highly reliable power supply solutions for users, which has great significance to the development of power distribution network. Multi-terminal coordinated control is an important foundation for the stable operation of AC/DC hybrid renewable energy systems. This article proposes typical control methods such as master-slave and droop for low-voltage AC/DC hybrid systems, and builds its test platform. The test environment which is close to real operating conditions is composed of renewable energy access modules, power distribution configuration modules and other components. Research on the coordinated control method of AC/DC hybrid renewable energy systems has been carried out on the test platform. The research results show that the system coordinated control test platform can test the dynamic performance of AC/DC systems under disturbances such as power fluctuations caused by renewable energy. It also provides effective technical support for the integrated operation of distributed renewable energy, new equipment such as power electronic transformers, and AC/DC loads.
