A HOPFIELD NEURAL NETWORK SOLUTION TO ECONOMIC DISPATCH PROBLEM INCLUDING TRANSMISSION LOSSES

Abstract

This paper presents a solution of economic dispatch problem (EDP) with transmission losses using a Hopfield Neural Network (HNN) algorithm. A direct computation method has been developed and used for solving the ED problem, which employs a linear input-output model for the neurons. Formulations for solving the ED problem are explored. Through the application of these formulations, direct computation instead of iterations for solving the problem becomes possible. Unlike the usual Hopfield methods, which select the weighting factors of the energy function by trials, the proposed method determines the corresponding factors by calculations. The effectiveness of the developed method is identified through its application to the 15-unit system. Computational results manifest that the method has a lot of excellent performances.
