Optimal Reserve Power Allocation of Power System in Critical Situation for Preparation against Threats

Authors

Abstract

Providing energy security in critical situation is one the most important issue in passive defence. Power system could face lack of power supply caused by attack in critical situation.  Injecting reserve power is a good tool to confront lack of power in this condition.  Reserve power must be allocated optimally based on current situation. This paper presents a new method for calculating system’s Energy not supplied based on optimal power flow. Then reserve power is allocated optimally by cost/benefit analysis. In critical situation, value of lost load and unavailability of components are increased and consequently the optimized value of reserve power is increased rather that normal situation. The presented method is tested on IEEE 24-bus test system and results have shown the efficiency of this method.
