Transient Behavior of WSCC 9-Bus Systems with Integrated PV and Battery Energy Storage System
Main Article Content
Abstract
The integration of renewable energy sources and battery energy storage systems (BESS) into power grids is essential for enhancing the reliability and sustainability of modern power systems. This study investigates the transient behavior of the Western System Coordinating Council (WSCC) 9-bus system with integrated photovoltaic (PV) generation and BESS. The analysis focuses on the system's dynamic response to transient disturbances, evaluating the impact of PV and BESS on voltage stability and overall system resilience. Using a simulation tool, authors model the WSCC 9-bus system and introduce transient scenarios to observe system performance. Our findings indicate that the integration of PV and BESS significantly improves the system's ability to withstand and recover from transient disturbances, enhancing reliability. The results provide valuable insights into the design and operation of future power systems with high penetration of renewable energy and advanced storage solutions. This study contributes to the growing body of knowledge on the dynamic interactions between traditional power systems and modern energy technologies, offering guidance for engineers and policymakers in optimizing grid integration strategies. This simulation was simulated in MATLAB 2021b version.
