POWER SYSTEM NODAL RISK ASSESSMENT : CONCEPTS AND APPLICATIONS

This paper discusses the concept of nodal risk, by characterizing a number of factors that may be utilized as useful indicators to the degree of importance of each power system node. The concepts of local and system-wide risk are proposed. A simplified and practical method is also developed for fast assessment of system nodal risk from the static point of view. A set of results is presented illustrating the method efficiency when applied to the Brazilian Southeast system.
