“…Liu et al [2] presented a dynamic description of the voltage collapse by characterizing the voltage stability region in terms of the continuous tap-changer model. Schlueter et al :3,4! introduced PQ and PV stabilities and controllabilities for the static voltage stability and presented a unified theoretical foundation for determining tests for voltage security conditions.…”

The static voltage stability and the dynamic voltage stability are integrated. To consider a shunt compensator and/or a more general load which is dependent on voltage, a modified criterion for the static voltage stability is developed and the system is controlled to satisfy this static Stability criterion. For an accurate analysis of the dynamic voltage stability, the system model includes excitation systems. tap-changers, capacitors and power system stabilizers in addition to network equations. -4 parameter optimization technique with a modal performance measure is developed to determine optimal control parameters for dynamic voltage stability enhancement.Kevwords -Voltage stability. static voltage stability. dynamic voltage stability, voltage collapse, voltage security. Static Voltage Stability CriterionKwatny [l! has shown that a static bifurcation exists that will result in voltage collapse when J;. is singular, where J;. is a sensitivity matrix for coupled Jacobian J in equation (2.1), and J;. = J r . when the decoupling approximation is made, i.e., the off-diagnol blocks are zero in (2.1).

Abstract-At the residential level, devices which are in place now and expected in the future have the ability to provide reactive power support. Inverters which connect distributed generation such as solar panels and pluggable hybrid electric vehicles (PHEVs) to the grid are an example. Such devices are not currently utilized by the power system. We investigate the integration of these end-user reactive-power-capable devices to provide voltage support to the grid via a secure communications infrastructure. We show how to determine effective locations in the transmission system and how to control reactive power resources at those locations. We also discuss how to determine reactive support groups which parallel the regions of the secure communications architecture that is presented. Ultimately, our goal is to present how the Smart Grid can allow the utilization of available end-user devices as a resource to mitigate power system problems such as voltage collapse.
