Reactive droop compensation
WebReactive droop compensation (droop) is an independent MVAR sharing control strategy that does not maintain generator output voltage; generator output voltage decreases for … Webthe reactive compensation. The single-phase DSTATCOM compensates for the reactive power deficiency in the phase while the DGs supply “maximum available active power.” During reactive power limit of the DG, the “maximum available active power” is fixed to a value lower than maximum active power to increase reactive
