Grid Connected Hybrid Energy Storage Structure with Renewable Energy Sources

Abstract

This study presents the design and analysis of a hybrid renewable energy system integrating multiple energy sources such as solar photovoltaic (PV), wind, and hydroelectric power along with advanced energy storage technologies including battery, hydrogen storage, and supercapacitor. The system is supported by a power conversion unit and controlled using an intelligent energy management system (EMS) to ensure efficient power flow and system stability. The proposed model utilizes converters and bidirectional energy flow to interact with the grid, enabling optimal utilization of generated and stored energy. A cooling system is also incorporated to maintain safe operating conditions of storage components. The system is analyzed under varying conditions to evaluate its performance in terms of reliability, efficiency, and stability. The results demonstrate that the proposed hybrid system effectively balances energy generation and consumption, reduces dependency on conventional sources, and ensures continuous power supply.
