Microgrid coordinated control system with VSG

Abstract

The microgrid coordinated control system makes the microgrid to be a controllable and stable power system, which has the great significance to the reliable operation of microgrid system. This paper presents a microgrid distributed coordinated control system, introduces several functions of this control system such as: grid connecting control, islanding control and black start control, and proposes the optimization solution for the issue of slow control speed and low control precision for virtual synchronous generator (VSG). Finally, this paper introduces the microgrid coordinated control system with VSG technology in practical application, Thailand Chiang Mai Ban Khun PEA microgrid project, verifies the feasibility of the proposed system.
