摘要：The pvg is a nonlinear AC source; its voltage output can be affected by climatic factors. So, in generalthe use of a potential converter in gcps is accompanied by a maximum power point tracking control mppt in order tomake the pvg working at its maximum power point. In our case, we choose to satisfy the grid requirement by tracking areference AC voltage fixed by the grid and not by the mppt.To insure this function, the buck-boost potential converter is controlled by the sliding mode control which aims thegeneration of the control signal d of the converter’s switches detailed in section b.This converter is controlled by the sliding mode control smc and a fuzzy sliding mode controller. The controllers areused to track the AC reference voltage which is used to satisfy the main grid. The second stage is composed of a ACbus and a three-phase voltage inverter, which serves as an interface to the pvg and the grid utility. The inverter output isregulated by means of suitable filters to inject the high quality pv power into the grid. The gcps has been implementedin the matlab software and further studies have been presented to evaluate its effectiveness. The performances of thefuzzy sliding controller are compared to the results obtained by a sliding mode controller. The satisfactory potentialresults thus show the efficiency of the proposed control law, which reduces the phenomenon of chattering. The resultindicates the robustness of the control law against variation of the load and the source voltage of the converter.
