Abstract: Simulated annealing is a probabilistic method for finding the global minimum of a cost function that may possess several local minima. In this paper, a Modified Simulated Annealing (MSA) technique is proposed to minimise the generation cost in Optimal Power Flow (OPF) control with Flexible AC Transmission Systems (FACTS) devices. The main goal of this paper is to verify the validity of using MSA to solve the OPF problem simultaneously composed by the load flow and the economic dispatch problem. A six bus system is used to highlight the goodness of the solution technique.

Keywords: MSA; modified simulated annealing; OPF; optimal power flow; FACTS; flexible ac transmission systems; power generation costs; load flow; economic dispatch.
