Simulating And Analyzing SA Distributed Solar Generating System In Transmission Line Expansion Network

Renewable generating focuses on reducing power losses. Photovoltaic (PV) technology is clean, safe, and pollution-free. Thus, PV power plants are essential in the energy sector. Transmission Expansion Planning (TEP) refers to the systematic and financially beneficial process of expanding power infrastructure to satisfy the projected demand for electric energy while maintaining an acceptable level of reliability. This study aims to utilize solar PV renewable energy sources (RES) to expand power transmission lines. The system utilizes Aggeneis-Paulputs, which consists of two 220kV 100km transmission lines in the Northern Cape of South Africa (SA). These two SS (substations) are connected to the Konkonsies (KK) II Solar PV (photovoltaic) system, which is situated 31 km from the Paulputs SS. Integrating renewable energy (RE) into the transmission line enhances electricity accessibility and ensure that the demand is fully satisfied. Additionally, a transient stability simulation is performed to analyze the dynamic behavior of the system.
