As the penetration of Variable Renewable Energy (VRE) generators into power systems escalates, concerns over system reliability and stability become increasingly pertinent. This research proposes a Power Oscillation Damping (POD) control scheme for a Photovoltaic (PV) system integrated with Battery Energy Storage System (BESS) to enhance system stability following electrical network disturbances. This method incorporates a POD controller for PV system and BESS, resulting in quicker oscillation damping compared to systems without battery integration. The designed POD strategy aims to supply additional active and reactive to meet the system's needs following a disturbance. Incorporating PV System and BESS is expected to significantly improve the system's stabilization process, thereby shortening the duration required for the system to return to a steady state. To accurately assess the POD control scheme on PV and BESS configurations for power oscillation damping, simulations are conducted using PSCAD 5.0 software to illustrate the system's post-fault conditions following short-circuit disturbances and changes in transmission system configuration. This study utilizes Prony Analysis methods as a tool to examine the damping effects on power oscillations. Prony Analysis can provide a deeper insight into the oscillatory modes and their damping ratios, enabling a more detailed evaluation of how the integration of PV and BESS influences the system’s dynamic response and stability. Through this approach, the research aims to underscore the critical role of PV System and BESS in bolstering grid resilience against the variability introduced by VRE sources.
