Abstract

This paper presents an alternative approach to voltage source converter based multi-terminal direct current (VSC-MTDC) performance analysis. The approach is to build a small-scale physical model of the VSC-MTDC transmission system, with renewable energies and integration devices. The platform is capable of investigating the operating performance, renewable energy integration, and control strategies of VSC-MTDC. Furthermore, it can be used to investigate the influences of renewable energy's random variation on VSC-MTDC system. Such complex phenomenon is very difficult to be investigated using digital simulation methods. Finally, simulations under normal operation and under the situation of wind power variation are carried out, and the results prove the feasibility and stability of the designed dynamic simulator.
