Coordinated Optimal Configuration Of Grid-Forming Inverters And Statcoms For Enhancing Transient Voltage Security Of Regional Power Grid, Xiaofeng Yu, Ronghao Tan, Binbin Tang, Shunjiang Lin, Ye Cheng, Weikun Liang

Journal of Electric Power Science and Technology

At present, renewable energy stations in a regional power grid mainly adopt grid-following control. Since it has the current source control characteristic and does not have the voltage support capability similar to that of traditional synchronous generators, it will reduce the transient voltage security of the regional power grid. When short circuit faults occur or the impact loads start up frequently in the regional power grid, it is more likely to result in the transient voltage instability and thus affect the secure and reliable power supply to users. In response, a coordinated optimal configuration model of grid-forming inverters and static …
