This paper presents an optimal algorithm control of photovoltaic generator system with battery energy storage. The system is the combination of photovoltaic (PV) array and battery storage via a common dc bus. The system components have substantially different voltage-current characteristics and they are integrated on the DC bus through power conditioning devices for optimal operation by using the developed Maximum Power Point Tracking (MPPT) control method. Using this method, it is possible to adapt the load to the PV modules and to follow the MPP howsoever the weather conditions may vary. This algorithm is based on perturbation and Observation (P&O) method with initial measurement of the tracking reference for estimating the step size to get the optimal operating point. The results show that the approach improves clearly the tracking efficiency of the maximum power available at the output of the PV modules and reduces the oscillations around the maximum power point.
