摘要：Combined Heat and Power Economic Dispatch (CHPED) plays a key role in economic operation of power systems. Due to complex characteristics, heuristic and evolutionary based optimization approaches have became effective tools to solve the CHPED problem. In this paper a new optimization approach based on improved differential evolution (IDE) has been proposed to solve the CHPED problem. IDE is an improved version of differential evolution optimization algorithm in which new solutions are produced in respect to global best solution. This approach leads the algorithm to optimum solution. The cause of CHPED problem difficulty is its constraints which are satisfied simply by using IDE. In order to demonstrate the applicability and efficien cy of the proposed IDE based approach, it has been tested on a standard test system and obtained results are compared with those obtained using other existing methods. Simulation results show that the proposed approach is superior to the other existing methods
