Abstract

In order to implement the optimal utilization of energy and stable running of system in the stand-alone PV generation system of microgrid,the control mode of DC-DC converter has to switch frequently between MPPT control and constant voltage control.And the two modes have its own control strategy and the whole control strategy is complicated.The paper proposes a new algorithm based on fuzzy-PID control,which utilizes the same fuzzy rules.It can not only complete the MPPT control,but also complete the constant voltage output control.And the control strategy of DC-DC converter in PV generation interfaces is simplified and the stability of system is improved.Finally,the simulation result shows that the control strategy is correct and effective.
