Lévy strategy based metaheuristic for smart grid

Abstract

Various events such as the difficulty of constructing new transport’s axes or natural phenomena encourage the Managers of the power systems to operate in their boundary conditions. It results in some unbalanced distribution of loads, provoking thus overloads of some and a reduction of the stability margin of the electrical system. FACTS (Flexible Alternative Current Transmission System) allow to control transits of potencies in an uninterrupted manner on a network. In this paper, we address the optimal placement and sizing of FACTS problem. We demonstrated that by choosing carefully the number of FACTS, their type, their location in the network and their sizing we perform very well the security of the power grid. In other hand, the results show that Lévy Particle Swarm Optimization (PSO) is demonstrated to perform as well, or better, than a standard PSO.
