Abstract
The power generation landscape evolves, with the increase of inverter-based resources (IBRs) such as solar photovoltaics and wind turbines, providing sustainable and clean energy sources. The shift towards IBRs mitigates climate change, creating considerable challenges to traditional power system protection due to their low fault current. Conventional protection schemes are designed around the internal dynamic of synchronous generators where they can supply an elevated fault current. This thesis explores a protection scheme designed to enhance the security of IBRs. The incremental characteristics of voltage and current coupled with the Permissive Overreaching Transfer Trip scheme (POTT) provide a remarkable ability to detect a spectrum of fault conditions with a marginal fault current. A spectrum of simulation studies is conducted to test the proposed protection scheme’s effectiveness under various fault conditions and transient change. The proposed solution affirms security during external faults and normal transient conditions. During extensive testing, the proposed protection solution proved its efficacy, utilizing the incremental quantity-based POTT scheme in protecting IBRs. The findings and the analyses ensure that there is a critical need for advanced protection with the IBRs penetration.
