Abstract: Multifaceted deeds of elephants are considered for a bio-inspired algorithm model. In this work reactive power optimisation problem is solved by elephant herd optimisation (EHO) algorithm. Normally elephants lead the life as clan under the single leadership of matriarch and during mathematical modelling population of elephants are alienated to have a mixture of relations. In each cycle of generation, male elephants leave their clan at matured stage and move far away from the clan. In first step of the algorithm elephant population are segregated as 'k' clans. Exploration and exploitation has been balanced throughout the process. Proposed EHO algorithm is evaluated in IEEE-30, 57,118,300 systems without considering voltage stability index. Then in IEEE 30 bus system with considering voltage stability index criterion, evaluation has been done. Voltage stability index value increased and power loss reduced considerably.
