Addressing Integration Issues And Improving Stability In Hybrid Renewable Power Networks

Abstract

The rapid penetration of renewable energy sources (RES) into traditional power systems is one of the major challenges to deal with in terms of system stability, security, and power quality management. Such integration in hybrid renewable power networks involves primarily exploring key integration issues in various operational aspects of hybrid renewable power networks and providing holistic solutions utilizing advanced strategies of stability enhancement. Main goals include voltage and frequency stability studies, energy storage-tied analysis and control studies of PV-WE hybrid systems and a plenty of examination among these two types of technology. The research is based on a descriptive-analytical approach that uses secondary data from government databases, statistics from IRENA and existing literature. It hypothesizes that the deployment of the energy storage systems and optimal control strategies enhances the grid stability of hybrid renewable networks substantially. Results prove that hybrid energy storage systems lead to a 35-45% cut of frequency deviations and improve voltage regulation within the required ranges. We use a global and publicly available dataset on renewable capacity statistics to show that total global capacity increased from 2537 GW in 2019 to 2799 GW in 2020, demonstrating the need to understand the accelerating integration challenges. The subsequent discussion synthesises findings about the optimal sizing, placement, and control of storage systems. Coordinated control frameworks that integrate battery energy storage with advanced power electronics considerably alleviates integration issues in hybrid renewable networks.
