—As a network of systems, electrical grid is complex in nature and requires sophisticated control structures to manage the network in stable operating region. These control structures depend on processing of data pertaining to states of the network, derived from voltage levels and power flow studies. Control actions invariably require logical methods of data analysis covering selected regions of the network. This paper investigates the role of a proposed new instability prediction index in characterizing the operating condition of a defined electrical network. The proposed instability calculation method is developed from the defining equations for real and reactive power flows in AC networks to characterize the network under consideration. By using the dependence of power flow on the network branch impedances, an indicator of the nodal voltage stability and weak line detection is developed. Analytical solution constraints for the power flow equations are utilized to derive the criticality of electrical networks in general, irrespective of the topological aspects. Analysis of typical network configurations, like three node, IEEE − 14, 69, 34 and 123 bus systems using the proposed method demonstrates the fast and easy determination of criticality of network operation.
