Abstract	This work presents the design and implementation of a hybrid power conversion system integrating solar energy, battery storage, and grid support to ensure reliable and efficient energy management. The proposed system employs a multi-stage power electronic architecture consisting of a DC–DC boost converter, a bidirectional buck–boost converter, and an AC–DC converter interconnected through a common DC link. The boost converter is utilized to regulate and enhance the variable output of the photovoltaic source, while the bidirectional converter facilitates controlled charging and discharging of the battery, enabling energy storage and supply balancing. The grid interface operates as a supplementary power source to maintain continuity during fluctuations in solar generation. A proportional–integral (PI) controller is implemented as the primary control strategy for regulating voltage and current across the system. To maximize energy extraction from the photovoltaic source, an incremental conductance (INC)-based maximum power point tracking (MPPT) algorithm is employed in conjunction with the PI controller. This approach ensures accurate tracking of the optimal operating point under varying environmental conditions. The bidirectional converter control is also governed by PI regulation to achieve stable energy transfer between the battery and DC link, thereby maintaining system equilibrium. The proposed configuration offers a simple, cost-effective, and reliable solution for hybrid energy systems. It demonstrates effective coordination between renewable generation, storage, and grid support while maintaining system stability and performance. The results validate that the combined use of PI control and INC-based MPPT provides satisfactory dynamic response, reduced steady-state error, and improved energy utilization. This work highlights the feasibility of implementing conventional control techniques for efficient operation of integrated renewable energy systems.
