So configuring a certain capacity of storage devices in order to ensure the supply reliable and continuous is necessary. Presented a PV program which the flywheel energy storage system was applied to as an auxiliary. Studied the control strategy to stabilize the DC bus voltage of the photovoltaic micro-grid. Using Matlab/ Simulink software，a simulation module for PV microgrid which is off-grid based on FESS was constructed. In the end，the effectiveness and flexibility of the control strategy is verified and the stability of the DC bus voltage is regulated.
