Modeling and Virtual Synchronous Generator Characteristics Research Based on Droop-controlled Inverters
Nowadays, the penetration of distributed power is ever-increasing. Stability problems are becoming more and more because the power system will gradually come into a power electronic converter-dominant network with low inertia and under-damped. How to control grid converter by the effective way to connect distributed power to power grid safely has become a study focus. Virtual synchronous generator technology based on droop-controlled can mimic the characteristics of synchronous generator and connect distributed power to power grid friendly. This paper set up a model of virtual synchronous generator and constructs one machine-infinity bus system case in Matlab/Simulink software in order to simulate the operating characteristics of virtual synchronous generator. The simulation result proves the feasibility of VSG technology and provides theoretical support for its application in the power grid.
