Economic power dispatch optimization

Abstract

With increasing demands for power and increasing energy scarcity, it is essential that power generation should be as efficient as possible. The power dispatch problem is a real-world power system problem that aims to schedule a given set of generators to meet the power load demand while fulfilling a given set of constraints. With equality and inequality constraints, the power dispatch problem is a highly non-linear optimization problem that requires powerful evolutionary algorithms to solve. In this paper, a form of evolutionary algorithm known as differential evolution is used to minimize the transmission loss in a power system. Variations of the standard differential evolution, such as SHADE, L-SHADE and L-SHADE EpSin, are also applied.
