The electric power system is one of the most important critical infrastructures of a country. Recently, the number of natural and man-made disasters is increased, which can impose extensive damages and costs to the power system. A resilient power system can withstand against, adapt to and recover from these disasters. Power system resilience is quantified by mathematical tools which are called “resilience metrics”. Currently, a lot of resilience metrics are proposed in the power system literature. In this paper, based on the extensive research in the critical infrastructure resilience literature which specifically concentrates on the “area-based” resilience metrics, a new area-based resilience metric is proposed which can measure the power system resilience considering the government policymaker criteria, which are rarely noticed before. The proposed and conventional area-based resilience metrics are evaluated based on the real data from the 2012 Superstorm Sandy in the USA, which led to significant damage to the power distribution system. The simulation results show that the proposed area-based resilience metric is very simple, can successfully address actual power system performance curves and is more meaningful and tangible than the conventional area-based metrics for the government policymaker. The proposed area-based resilience metric has also a general form and can be used for other critical infrastructures.

Recently, there has been a focus on natural and man-made disasters with a high-impact low-frequency (HILF) property in electric power systems. A power system must be built with “resilience” or the ability to withstand, adapt and recover from disasters. The resilience metrics (RMs) are tools to measure the resilience level of a power system, normally employed for resilience cost–benefit in planning and operation. While numerous RMs have been presented in the power system literature; there is still a lack of comprehensive framework regarding the different types of the RMs in the electric power system, and existing frameworks have essential shortcomings. In this paper, after an extensive overview of the literature, a conceptual framework is suggested to identify the key variables, factors and ideas of RMs in power systems and define their relationships. The proposed framework is compared with the existing ones, and existing power system RMs are also allocated to the framework’s groups to validate the inclusivity and usefulness of the proposed framework, as a tool for academic and industrial researchers to choose the most appropriate RM in different power system problems and pinpoint the potential need for the future metrics.

In a power system, voltage stability margin improvement can be done by regulating generators voltages, transformers tap settings and capacitors/reactors rated reactive powers (susceptances). In this paper, one of these methods, which we name “reactive power rescheduling with generator ranking”, is considered. In this method, using “ranking coefficients”, the generators are divided into “important” and “less-important” ones and then, voltage stability margin is improved by increasing and decreasing reactive power generation at the important and less-important generators, respectively. These ranking coefficients are obtained using “modal analysis”. In this paper, the method’s performance for two types of ranking coefficients has been analyzed. Also, for comparison purpose, the “usual form of optimal reactive power dispatch” method has been simulated. For all simulations, the IEEE 30 bus test system has been used. The simulation results show that in the former method, for either type of ranking coefficients, voltage stability margin is considerably improved and, usually, the system active loss and the system operating cost are increased. Also, in the latter method, voltage stability margin is improved and the system active loss and the system operating cost are decreased.

The simulation results show that in this method, voltage stability margin is considerably improved and, also, the system active loss and the system operating cost are increased.

In this paper, the "usual form of optimal reactive power dispatch" and "reactive power rescheduling with generator ranking" methods are considered. In the first method, the system active loss is minimized subject to power flow equations and other system constraints. In the second method, using "ranking coefficients", the generators are divided into "important" and "less-important" ones and then, voltage stability margin is improved by increasing and decreasing reactive power generation at the important and less-important generators, respectively. These ranking coefficients are obtained using modal analysis. In this paper, with extending the work of previous papers and using new notations, modal analysis is presented in a new form and some of the ambiguities in the previous papers are cleared. The first method and the second method (for 3 types of ranking coefficients) are simulated using IEEE 30 bus test system. The results show that these methods can improve voltage stability margin significantly.
