This paper deals with the control of a grid-connected multi-source power system based on a photovoltaic (PV) array and a battery energy storage system (ESS), taking into account the variable and intermittent characteristics of the solar irradiation level and the ambient temperature in Morocco. The PV generator is connected via a dc-dc boost converter to a common dc bus which is connected through a bidirectional dc-dc converter to the battery ESS. The dc bus output is connected to the mains via a PWM dc-ac converter with an LCL filter. The control technique consists of three parts: the PV array is considered as the primary source and the boost converter is controlled locally to generate the maximum power extraction (MPPT), while the bidirectional dc-dc converter of the ESS battery is controlled to ensure the energy balance according to the power flow under different solar irradiation and temperature conditions. The PWM inverter is controlled to regulate the DC bus voltage and maintain the power factor at the unit. The system is implemented in Matlab/Simulink environment. The effectiveness of the control strategy is carried out by simulation results.
