Recently power losses and voltage volatility issues are the real issues in power system and production cost likewise goes high. Certainties idea made a revolution in power system which conquers every one of the issues. Numerous strategies are utilized to optimize the area of FACTS gadgets. Among the few FACTS controllers, the paper introduces the Unified Power Flow Controller (UPFC) to enhance the improvement of voltage stability and decreases the power loss. Here, the hybrid model (KHSO) i.e. Krill Herd Optimization (KHO) and Particle Swarm Optimization algorithm (PSO) are proposed for enhancing the voltage dependability of the power transmission systems. The hybrid construct approach is connected in light of IEEE 30 BUS System. From the power stream examination, bus voltages, active power, reactive power, cost and power loss of the transmission systems are resolved. The voltages of the buses with and without UPFC are likewise revealed. It is evidently apparent from the outcomes that viable position of UPFC in appropriate areas can fundamentally enhance system execution. The outcome demonstrates that voltage profile is improved at buses and power losses are impressively diminished minimization of power losses and minimization of generation cost. Accordingly, it demonstrates that the productivity of KHSO is superior to the conventional technique (Firefly and GA).
