Robust Power Frequency Control for Pumped Storage Hydropower Station

This research study explores the impact of Sliding Mode Control (SMC) controllers and pumped storage hydro power stations on the frequency stability of a two-area power system. A comprehensive simulation model is developed to evaluate the system's response to load disturbances. The findings reveal that the implementation of SMC controllers yields significant improvements in frequency stability compared to conventional Proportional, Integral and Derivative (PID) controllers. The frequency deviation is reduced by an impressive 43%, demonstrating the remarkable effectiveness of SMC controllers in regulating and maintaining system frequency. Furthermore, the integration of pumped storage hydro power stations into the system enhances its frequency response characteristics, resulting in minimized frequency deviations during generating operations. This synergistic combination of SMC controllers and pumped storage units offers a highly promising and robust approach to achieve reliable frequency regulation and mitigate the adverse effects of load disturbances in power systems. These results underscore the vital role of advanced control strategies and renewable energy storage solutions in ensuring a stable, resilient, and sustainable electricity supply.
