Virtual Synchronous Generator Technology and Its Application in PV-Storage Micro-grid |
| |
| Abstract: | In order to improve power supply reliability of substation power supply system, energy storage inverters based on virtual synchronous generator (VSG) technology and its application in PV-storage micro-grid is studied in this paper. The topology of micro-grid and its different working modes are introduced and the parameters of the subsystems are designed. The mathematical model of energy storage inverter based on VSG is built. The grid-connected and stand-alone control modes of VSG and the transitions between them are analyzed. Through PV-storage micro-grid system in 500kV River Li substation experiment results, using 100kVA energy storage inverters, the feasibility and effectiveness of the VSG control strategy is verified. |
