Abstract

With the development of new energy generation, Modular Multilevel Converter (MMC) based HVDC (MMC-HVDC) systems have drawn much attention internationally. This paper focuses on researching the steady and dynamic operating characteristics of an MMC based multi-terminal VSC-HVDC system using the RTDS Simulator. A three-terminal MMC-HVDC system is set up and the operating characteristics of a multi-point DC voltage coordinated control strategy are analyzed. Furthermore, several typical AC and DC contingencies are simulated. The simulation results show that the coordinated control strategy performed well when the MMC-HVDC system operated normally and even when one station was out of service.
