Summary
A static security region is a tool that provides information on the steady‐state security conditions, for a given operating point, of a power system in an efficient way. Although this tool aims to be used in the online environment, one of its main characteristics is the high computational time required in the construction process. In this context, this article proposes a new methodology to construct these regions based on the particle swarm optimization (PSO) algorithm to improve computational performance. The proposed adjustments for the PSO algorithm parameters are detailed as well as the process to generate the initial population. The proposed methodology is validated through the study of two power systems. The first one is the well‐known New England system, and the second one is an equivalent of the southern Brazilian system. The presented results validate and clearly indicate the effectiveness of the proposed technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
