Power System Stability Improvements Through Grid Forming Inverters for Systems with High Penetration of Grid Following Inverters
Year: 2024
Type: conference-paper
Abstract: The power transmission system is rapidly changing due to the integration of renewable sources such as wind and solar power. However, these additions are converter-based hence their behavior is different from traditional synchronous generator-based power systems. In addition, the majority of the converters are grid-following inverters and a high share of grid-following inverters can have adverse effects on the power system stability. To mitigate the adverse effects, a new concept called grid-forming inverters is emerging. This paper studies the ability of the grid-forming inverters to maintain the power system stability under high inverter-based resource scenarios up until 100% inverter-based resource share. The research identified that the two-area Kundur model is stable up to 50% grid following inverter share and with the use of a sufficient share of grid-forming inverters, the system can reach up to 100% inverter-based resource share. Furthermore, the location sensitivity of the grid-forming inverter and the effects of different power flow scenarios at high inverter-based resource share were studied.
