摘 要：The Virtual synchronous generator (VSG) is an inverter based generating unit that uses a synchronous generator model to insert virtual inertia to power system. In this research, the parameters of the VSGs of the multi-VSG system are tuned to obtain the desired response. First, the multi-VSG microgrid is introduced. Then Particle Swarm Optimization is implemented to tune the parameters of the VSG units in the microgrid. Further, the virtual inertia control is applied to the VSG units to improve its stabilization. The simulations in PS CAD are represented for three conditions of VSG parameters and the results are compared.
