Modified simulated annealing technique based Optimal Power Flow with FACTS devices

摘要

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.
