The Review on Voltage Stability Analysis of Power Systems with SolarDistributed Generation using VCPI

Abstract

This comprehensive review paper investigates the challenges and strategies of maintaining voltage stability in power systems integrated with solar distributed generation, focusing on the application of the Voltage Collapse Proximity Index (VCPI). As renewable energy, particularly solar power, becomes increasingly prevalent in power grids, understanding its impact on voltage stability is crucial. VCPI emerges as a vital tool in this context, offering a reliable measure for assessing the risk of voltage instability. This paper synthesizes various research findings and methodologies related to VCPI, highlighting its role in enhancing grid resilience against voltage instability in solar-integrated systems. The results indicate that VCPI is effective in predicting voltage collapse, especially in scenarios with high solar power penetration. This review not only collates data from diverse studies to present a coherent view of the current state of voltage stability in solar-integrated power systems but also identifies gaps and suggests directions for future research. It aims to provide a foundation for enhancing voltage stability mechanisms and strategies in power systems with a growing reliance on solar energy. This work is particularly relevant for researchers and practitioners seeking to optimize the integration of renewable energy sources into existing power grids while maintaining grid stability and reliability.
