Method for Controlling an Electric Power Generation System Based on Energy Sources, in Particular Renewable Energy Sources, and Related Controller Device
The present invention concerns a method, and the related controller device, for controlling an electric power generation system, based on at least one energy source, in particular a renewable energy source, preferably a photovoltaic or fuel cell source, said system operating according to operating performance representable by at least one performance indicative function (P; ?P) having at least one optimal value (P target), operation of said system being dependent on at least two controllable parameters (Vc, K; ?cmd, ss), the method perturbing the values of said at least two controllable parameters (Vc, K; ?cmd, ss), so as to perturb a first controllable parameter (X; Y) with a same perturbation sign (SX) as long as it is detected that, after each single perturbation, a distance of a value of said at least one performance indicative function (P; ?P) from said at least one optimal value (Ptarget) decreases, whereas when it is detected that said distance increases, the method passes to perturb a different controllable parameter (Y) with a perturbation sign (SY) opposite to the sign of the immediately preceding perturbation of such different controllable parameter (Y).
