Device And Method For Controlling The Voltage Of Microgrids

The present invention concerns a device for controlling a plant with an electricity generation and/or electricity storage unit and a connection terminal intended to be connected to a microgrid, comprising an automatic controller () configured to compute a setpoint voltage Uof each unit, members () for measuring or determining a total active power P, a voltage Uof the terminal, of a voltage reference Uaccording to a function f depending at least on the total active power P, of a first individual reactive power Qof each unit, a first voltage corrector (), having a second prescribed transfer function corr, the automatic controller being configured to compute U=f(P), and U=corr(U−U) and U=U−K−Q.
