A FAST-COMPUTATION HOPFIELD METHOD TO ECONOMIC-DISPATCH OF POWER-SYSTEMS

This paper develops a direct-computation Hopfield method for solving t he economic dispatch (ED) problems of thermal generators. The method e mploys a linear input-output model for neurons. Formulations for solvi ng the ED problems are explored. Through the application of these form ulations, direct computation instead of iterations for solving the pro blems becomes possible. Not like the usual Hopfield methods which sele ct the weighting factors of the energy function by trials, the propose d method determines the corresponding factor using formulation calcula tion. Hence, it is relatively easy to apply the proposed method. The e ffectiveness of the developed method is identified through its applica tion to two example systems. Computational results manifest that the m ethod has a lot of excellent performances, and it is superior to other methods in many respects.
