Enhancing Grid-Integrated Renewable Energy Systems: Modelling and Performance Evaluation of Wind-PV-BESS Hybrid Power with PMSG Extension

Abstract

The imperative to meet rising energy demands while minimizing environmental impacts has led to increased integration of renewable energy sources into the grid. This study introduces an advanced modeling and performance evaluation of a grid-integrated Wind-Photovoltaic-Battery Energy Storage System (Wind-PV-BESS) hybrid power system, with an extension using a Permanent Magnet Synchronous Generator (PMSG). The model encompasses individual components such as wind turbines, photovoltaic panels, a doubly fed induction generator (DFIG), PMSG, and battery energy storage. A sophisticated control algorithm integrates these components, optimizing power flow and ensuring seamless grid interaction. The enhanced DFIG-PMSG configuration is designed to improve power generation, particularly under low wind conditions, by leveraging both induction and synchronous generator technologies. Performance is evaluated through simulations under various conditions, including changes in wind and solar levels, grid disturbances, and load fluctuations. The study finds that this integrated system enhances operational flexibility, increases renewable energy penetration, and improves grid stability, offering valuable insights for the design and optimization of future hybrid renewable energy systems.
