Risk assessment of infrastructures against threats, is one of the most important consideration in passive defence. Power system is an infrastructures on which other infrastructures are depended. This infrastructure is always regarded by terrorists as an attractive target. This paper presents a method for risk assessment of power system. It also presents a method for risk reduction of power system based on optimal allocation of defence budget for hardening facilities of power system. First, probability model of successful terrorist attack to power system’s facilities is presented and by combining of this probability and consequences of attack, risk of each scenario is achieved. Then, power system’s defence budget is optimally allocated for hardening its facilities. In order to indicate the effectiveness of these methods, IEEE 24-bus reliability test system is tested. Results show how system’s risk is reduced by the allocation of defence budget for system protection.
