Back-Pressure Cogeneration Economic Dispatch For Physical Bilateral Contract Using Genetic Algorithms

摘要

A method based on genetic algorithms (GA) is proposed for economic dispatch among multi-plant (cogeneration systems) with multi-generators, which transmit MW to designated buyers (load buses) via physical bilateral contracts. The operation constraints in the cogeneration systems were considered. Virtual Lagrange multipliers were proposed for enhancing the convergence speed to optimality. GA parameters were also investigated for the convergence performance. The IEEE 30- and 118-bus systems were used as test systems to illustrate the applicability of the proposed method
