Abstract:
This paper explores the impact of Virtual Synchronous Generator (VSG) on the stability improvement by carrying out experiments on a power system with massive Photovoltaics (PV) penetration. In order to perform such studies, the prototype VSG is developed and connected to an analog simulator having rotating type reduced scaled synchronous generators and PV models. In developing the prototype VSG, an inverter, a regenerative type DC power supply and a controller board are used to realize its hardware part, whereas its software features are realized by simulating the synchronous generator behavior on a real time digital simulator capable of interacting with the inverter through the controller board so called hardware-in-loop configuration. Finally, the impact of different PV penetration levels on the dynamic and transient stability was evaluated in terms of synchronizing and damping power coefficients by performing experiments using an analog simulator and PV models. Also, the effectiveness of the VSG is checked experimentally to improve these coefficients vis-a-vis dynamic and transient stability of a power system with a massive PV penetration level.
