Abstract

The power system consists of interconnected generation, transmission, and load centres, forming a complex electrical network called a grid. One of the significant challenges in power systems is ensuring stability—the system's ability to return to regular or stable operation (steady state) after experiencing significant disturbances such as generation loss, switching operations, sudden load changes, or faults like short circuits. Transient analysis plays a crucial role in determining the appropriate relay operation scheme, critical disconnection time for circuit breakers, and the transfer capability between systems, all of which must be optimised to maintain stability. This study simulates and analyses the frequency transient stability to assess system reliability during disturbances of the 150 kV South Sulawesi interconnected system. The study also determines the Critical Clearing Time (CCT) necessary to achieve the stable conditions of the interconnected system. The simulation is tested on the South Sulawesi interconnected system. The analysis results show frequency drops of about 0.0397% at GI Bantaeng and 0.0401% at the GI Punagaya bus, PLTU Jeneponto 1, and PLTU Jeneponto 2.

Abstract

This study analyses the impact of integrating a solar photovoltaic power plant (PLTS) on the voltage stability of the 500 kV Java-Bali transmission system, with a case study on the Cirata Floating Solar Power Plant. With the increasing use of renewable energy, particularly solar PV, it is crucial to understand how the integration of this variable energy source affects the reliability and stability of the power system. The Cirata Floating Solar Power Plant, the largest of its kind in Asia, has a capacity of 145 MW AC or equivalent to 192 MWp. However, integrating the Cirata Floating Solar Plant into the transmission system may potentially affect voltage stability, necessitating an in-depth analysis to assess its impact. The methodology employed in this study includes static voltage analysis through PV curve evaluation and dynamic voltage analysis to determine the system's capability to maintain or restore voltage within permissible stability limits. The study utilises DigSILENT PowerFactory software to simulate system conditions before and after the PLTS integration. The results indicate that the Cirata Floating Solar Plant’s power injection of 192 MWp improves voltage quality and enhances system stability compared to the pre-integration conditions.
