A fuzzy logic based approach to direct load control

Power system demand side management programs are strategies designed to alter the shape of the load curve. In order to successfully implement such a strategy, customer acceptance of the program is vital. It is thus desirable to design a model for direct load control which may accommodate customer preferences. This paper presents a methodology for optimizing both customer satisfaction and electric utility unit commitment savings, based on a fuzzy load model for the direct load control of appliances.
