A Novel Control Operation Switching Strategy in Virtual Synchronous Generator

In micro grid, with purpose of ensuring the safe and stable operation of the inverter, it is necessary to switch the operation mode of the inverter according to the actual operation. In this paper, the virtual synchronous generator (VSG) is modeled and simulated. Taking VISMA model as the research object, the active control module and the reactive power control module are improved. Simulation model is established on MATLAB / Simulink to verify the effectiveness and feasibility of the proposed control strategy.
