Adequate reactive power reserve and voltage stability margin are important issues for secure operation of power system. Adequate reserve and margin is achieved by suitable settings of reactive power control variables. In view of this a novel technique to achieve the above mentioned objectives has been described in this paper. A quadratic performance index which minimizes deviation of reactive power generation from average generation output of the generators. This assures adequate reactive power reserve at various PV-buses on the lower as well as upper bound sides. The fitness function has been minimized using Jaya algorithm subject to desired voltage stability margin and accounting all equality and inequality operating constraints. The developed algorithm has been implemented on two standard test systems. The result obtained has been compared with those obtained using Teaching Learning Based Optimization technique (TLBO), Differential Evolution (DE) and Coordinated Aggregation Particle Swarm Optimization (CAPSO).
