Stability Improvement of Renewable Source Integrated Hybrid System Using SVC Controller and ALO Technique

Abstract

AbstractHybrid power system model is facing too many stability issues for its real and reactive power imbalance. The power issues may be overcome by using different control strategy, namely, automatic generation control and automatic voltage regulator (AVR) control. Only the AVR control is not enough for the reactive power challenges in the hybrid power system model (HPSM). Therefore, this paper focuses on the reactive power control of a wind, micro-hydro and diesel HPSM. The optimization of reactive power and minimize the voltage fluctuations to improve the stability of the HPSM, FACTS devices has been used. This paper presents the reactive power optimization which in turns improves the stability of the considered HPSM using static VAR compensator (SVC). This paper also addresses the antlion optimization (ALO) technique for optimize the HPSM parameters. The better optimized of parameters ensure the better reactive power optimization of the HPSM. The obtained results are also compared with another soft computing technique, i.e., binary coded genetic algorithm (BGA) technique.KeywordsHybrid power system modelReactive power optimizationStabilityStatic VAR compensatorAntlion optimization
