Design and modeling of a reactive power compensation system for grid stabilization in renewable energy integration

Abstract

In the context of students studying renewable energy sources, it is important to understand how the integration of renewable energy sources into isolated electrical systems is carried out. This aspect presents significant challenges related to voltage stability and power quality. The present study focuses on modeling a reactive power compensation system to stabilize a solar-powered network using MATLAB/Simulink. Two simulation models were developed: one employing capacitor banks and the other utilizing a Static VAR Compensator (SVC). The simulations incorporated both dynamic phasor and steady-state analysis methods. Results indicate that while capacitor banks offer a cost-effective solution for steady-state reactive power compensation, SVCs provide superior dynamic response and voltage regulation. The study concludes that a hybrid approach, combining both technologies, can enhance grid stability and ensure reliable integration of renewable energy sources in remote areas. This paper emphasizes the importance of managing reactive power in the transition to sustainable energy systems and the way to develop problem-solving skills for this type of issue among master's students in renewable energy studies.
