In this paper, optimal power flow (OPF) using grass hopper optimization algorithm (GOA) is addressed. OPF is a basic tool for economical and secure operation of power system. Here, the generator fuel cost and voltage profile are considered as main objectives with constraints. The GOA is a metaheuristic swarm based optimization algorithm. It mimics the natural behaviour of grass hopper. The GOA is implemented on IEEE-30 bus system to solve OPF problem. Results show the ability of GOA to reduce the voltage deviation. It demonstrates that the GOA is capable to improve the voltage profile of system buses.
