Reactive power Q and bus voltage V are direct mea-surement parameters of voltage stability for microgrid systems. When the V–Q sensitivity of all buses in the system is positive, the voltage of the power system is stable. If at least one current V–Q response is negative, the voltage of the power system is unstable.
