Effective Power Management of PV/ Battery Hybrid System Under Varying Frequency Modes

This paper presents an effective power flow management of microgrids system, which includes PV array, pack of batteries and variable AC load. The aim is validating the control strategy of the PV hybrid storage system under high fluctuation of the local load demand and PV power generation. The strategy is basing on the control of the constant time of frequency approach applied to batteries depend on load demand and the operations conditions of the PV array. The purpose of the work is keeping the state of health of battery, limit the battery dynamic stress and deliver the energy to the load under bad weather conditions and system fluctuation. The whole system is implemented and simulated using MATLAB/Simulink program and the extracted simulation results of the proposed control strategy are used to manage the efficient performance of the PV hybrid system.
