DEVELOPMENT OF CONTROLLER FOR ECONOMIC LOAD DISPATCH BY GENERATING UNITS UNDER VARYING LOAD DEMANDS

The paper presents a simulink model of controller for feeding power to the load by the generator, in a group of generators according to power demand imposed by the conditions of economic load dispatch on the generating plant. The knowledge base that correlates throttle opening of governor with specific power demand has been derived using experience based training of a feed forward network and the same has been used to operate a proposed feedback controller. The controller ensure that the power delivered by the generator equals the power demand on a specific generator for a given load state, while maintaining economic load dispatch. The simulink model of the feedback controller shows that the power delivered by a generator operating in parallel with other generators is same as the one provided by ANN trained modal. The work can be extended for developing a real time controller that enables the generator to supply power equal to power demand determined by the conditions of economic load dispatch.
