Optimal Load-Sharing Strategy in a Hybrid Power System Based on PV/Fuel Cell/Battery

Hybrid power system integrates PV, fuel cells, and batteries. The goal is to enhance load sharing, reduce transient charging and discharging for battery longevity, and demonstrate fuel cell power responses with a battery. In this system, PV is weather dependent, while fuel cells offer steady power. Batteries improve fuel cell performance and life span. Load balancing is achieved by proportionally distributing power production among sources based on their capacity and qualities. Simulations show that PV (85.2 kW), fuel cell (6 kW), and the battery (10 kWh) meet a 100 kW demand. The system prioritizes PV and fuel cells but activates the battery when needed, reducing battery strain. Staggered operation optimizes efficiency and battery life. The battery aids PV and fuel cells with an additional 10 kW of power. This approach improves component power management, extends battery life, and measures fuel cell responses.
