“…However, widespread interruption and cascading remain possible, especially if these contingencies are accompanied by other system vulnerabilities that can result in complex contingencies. Identification and analysis of complex contingencies in Idaho Power system became important issues that have been investigated in recent work in both planning and operation environments [3]- [5], Reference [4] presents a risk-based approach for contingency analysis implemented at Idaho Power Company.…”

“…The practical approach to identify and analyze the effects of complex/extreme contingencies is presented in [5], The identification and mitigation of system risks and vulnerabilities as results of extreme contingencies, that are critical to ensuring the reliable operation of the bulk electric system (BES), is presented in [5], It is very important to identify contingencies that lead to voltage instability, widespread power disruptions and the vulnerability of the power grid to cascading. The aim of this planning study is to perform a comprehensive evaluation of five base cases by applying a great number of n-2 initiating events and to identify those events that potentially can lead to cascading…”

“…Idaho Power, since the major blackout event on July 2 nd , 1996 that originated in its service territory, continuously evaluates and study its system to ensure that its performance meets not only North Electric Reliability Corporation (NERC) standards and WECC Reliability Criteria [l]- [2] but also going beyond those requirements [3]- [5]. Idaho Power system is a portion of the Bulk Electric System (BES) in the Western Interconnection.…”

“…Understanding cascading outages and being able to predict the associated risks is becoming an integral part of planning and operation studies by Idaho Power [5], In order to achieve the secure operation ofthe system under not just traditional n-1 and credible n-2 contingencies but also under other type of n-k contingencies with high risks, Idaho Power has developed a comprehensive risk-based methodology [3].…”

The paper presents an initial comparison of a transmission planning study of cascading outages with a statistical analysis of historical outages. The planning study identifies the most vulnerable places in the Idaho system and outages that lead to cascading and interruption of load. This analysis is based on a number of case scenarios (short-term and long-term) that cover different seasonal and operating conditions. The historical analysis processes Idaho outage data and estimates statistics, using the number of transmission line outages as a measure of the extent of cascading. An initial number of lines outaged can lead to a cascading propagation of further outages. How much line outages propagate is estimated from Idaho Power outage data. Also, the paper discusses some similarities in the results and highlights the different assumptions of the two approaches to cascading failure analysis.

“…Developed methodologies and tools to assess system performance have served the industry very well in the past [35]- [37]. However, it is becoming more apparent that reliable operation of the power system is highly dependent on the reliability of the associated cyber system, and failure in the cyber system can result in undesirable consequences.…”
