Abstract:
Optimal Reactive power Dispatch is an important case of optimal power flow (OPF) problems. These optimal power flows problems are solved by using many swarm based algorithms are used. This swarm based algorithms some achieve better global optimal solutions, and many do not achieve the global optimal solution. When this paper study about newly introduce Firefly algorithm and this algorithm how to implement to solve optimal power flow problems and how to achieve better global optimal solutions are briefly discussed in this paper.

Keywords: Optimal Reactive power dispatch, optimal power flow, swarm based algorithm, Firefly algorithm
