The case studied in this paper relates to the control of a system photovoltaic. As the output characteristic of a photovoltaic (PV) module is nonlinear and changes with solar irradiance and the load, its maximum power point (MPP) is not constant. Therefore, a (MPPT) technique is needed to draw peak power from the PV module to maximize the produced energy and voltage delivered by the PV system constant under varying conditions. In our study, we used two MPPT algorithms, the algorithm “Perturb and Observe” (P & O), then the algorithm “Increment of Conductance” (IncCond). For this, a control system is presented. The methods used for the simulation of this system are based on the use of a sliding mode control. Simulation results are presented to verify the simplicity, the stability and the robustness of this control technique against changes in weather conditions.

Przypadek opisany w tym artykule dotyczy kontroli fotowoltaiki systemowej. Ponieważ charakterystyka wyjściowa modułu fotowoltaicznego (PV) jest nieliniowa i zmienia się wraz z natężeniem promieniowania słonecznego i obciążeniem, jego maksymalna wartość mocy (MPP) nie jest stała. Dlatego technika (MPPT) jest potrzebna do pobrania mocy szczytowej z modułu fotowoltaicznego w celu zmaksymalizowania wytworzonej energii i napięcia dostarczanego przez stałą systemu PV w różnych warunkach. W naszym badaniu wykorzystaliśmy dwa algorytmy MPPT, algorytm "Perturb and Observe" (P & O), a następnie algorytm "Increment of Conductance" (IncCond). W tym celu przedstawiono system kontroli. Metody użyte do symulacji tego systemu opierają się na zastosowaniu sterowania w trybie ślizgowym. Przedstawiono wyniki symulacji, aby zweryfikować prostotę, stabilność i odporność tej techniki sterowania przed zmianami warunków pogodowych.
