Abstract

Independent photovoltaic system needs energy storage in order to balance the power and improve its instability of power generation. A scientific control strategy can combine the PV cells to the battery system organically. The lithium-ion battery can be the bridge to achieve this target. This paper presents a control strategy which takes count of battery electrical performance and system instability based on optimization on the circuit topology of bi-directional DC/DC already underway. Moreover, the charge and discharge circuit based on bi-directional DC/DC converter and an integral independent PV power system are built with MATLAB, The simulation results show the correctness of the charge and discharge circuit topology and control strategy.
