Power quality enhancement in hybrid renewable energy systems for smart grid applications using optimized upqc

Abstract

newline In the evolving landscape of smart grid applications, the integration newlineof renewable energy sources represents a critical frontier, addressing both newlineenvironmental concerns and the need for enhanced power quality. Traditional newlinepower systems face significant challenges, including environmental newlinesustainability concerns and a growing demand for improved reliability and newlineefficiency. The intermittent nature of renewable source, such as solar and newlinewind power, necessitates innovative solutions to seamlessly incorporate them newlineinto smart grids. Moreover, as the global energy landscape evolves, research newlineefforts aim to address issues related to voltage fluctuations, harmonics, and newlineload balancing, emphasizing the critical role of renewable energy in newlinemitigating these challenges. As such, this research begins by introducing a newlinesmart grids applications for power systems operation aimed at enhancing newlinepower quality and flow in transmission lines, addressing issues, like unwanted newlineharmonics and compensating for sag and swell in power sources. To achieve newlinethis, a Flexible Alternating Current Transmission System (FACTS) device is newlineemployed, implementing a series compensator in parallel with a Three-phase newlineFour Wire (3P4W) distribution systems in the first contribution. The proposed newlinecompensator circuit, GTO Thyristor-Controlled Series Capacitor (GCSC), newlinecombines Thyristor-Controlled Series Compensator (TCSC) and Gate Turn newlineOff (GTO) for switching. Control of the proposed compensator involves newlineutilizing a Proportional Integral Resonant (PIR) controller, with optimization newlineof its parameters achieved through the Rock Hyraxes Swarm Optimization newline(RHSO) algorithm.
