An approach to overcome the fluctuation of power generation under the influence of temperature and light intensity by utilizing a hybrid electrochemical energy storage of photovoltaic (PV) DC microgrid system. It can perform peak load shifting of power generation. The I-V curves were formed from different light and temperature conditions by simulating the PV array mathematical model, and the Maximum Power Point Tracking (MPPT) of power generation was acquired with a modified disturbance observation method. We have devised a balanced energy storage strategy using a non-isolated bidirectional DC/DC converter connected to a DC bus and a hybrid electrochemical battery to achieve the management of battery. The double closed-loops improve the energy storage system, which the inner loop controls the battery current and the outer loop regulates the DC link voltage. To increase the generation power and solve the imbalance of power by storing the PV power generation in the energy storage battery. The acquired simulation and experiment results have demonstrated feasibility of the proposed system.
