DEVICE AND METHOD FOR CONTROLLING THE VOLTAGE OF MICROGRIDS

The present invention relates to a device for controlling a power generation unit and/or electricity storage center and connection terminal intended to be connected to a microgrid, comprising a control automaton (100), configured to calculate a reference voltage Uref(i) for each unit, measurement or calculation means (1, 2, 3, 4i, 5) of a voltage URmes of the common connection terminal (10), of a voltage reference UcentraleRef according to a function f, of individual reactive power Qmes(i) of each unit, a voltage corrector (5), having a second prescribed transfer function corr, the automaton being configured to calculate Uoffset=corrUcentraleRef−URmesUrefi=Uoffseti−KUQi.Qmesi, the control automaton (100) comprising a receiving means (5) for remote measurement values (Udecentralized-sources-k) of voltage telemetry of decentralized sources of the microgrid and values (Uconsumer-stations-l) of voltage telemetry of decentralized consumer stations of the microgrid.
