Risk Level Assessment of the Power Supply Network Against Various Threats
Message:
Abstract:
The aim of this paper is to provide a new approach for assessing the risk of a power system against natural events and the threats imposed by the terrorist attacks. In this regard, the main determinants of the importance of an area are quantified in the form of 16 introduced items. Subsequently, by combining these 16 sub-indicators, the main index for risk assessment is calculated for each region. In order to analyze the total risk of the system, the outage probability of each element (including the transmission line and the bus) is determined considering the sixteen proposed factors involved. Finally, a new model is proposed to calculate the unserved power of each event using the proposed risk index and region value. The proposed method has been simulated on the geographic information of a case study. The proposed model can help to identify the critical points, as well as the quantitative assessment of the vulnerability level.
