The operating conditions of the present day distribution systems are closer to the voltage stability boundaries due to the ever increasing load demand. This article presents a biogeography based optimization (BBO) algorithm for determining the optimal locations and sizing of static and/or switched shunt capacitors with a view to enhance voltage stability of distribution systems. Biogeography deals with geographical distribution of biological species. Mathematical models of biogeography portray how species arises, migrates from one habitat to another and gets smeared out. The BBO algorithm searches for global solution through migration and mutation. The superiority of this approach is demonstrated by testing the algorithm on 15, 33 and 69-node distribution systems.
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.
