Optimal Scheduling Method of Cogeneration System with Heat Storage Device Based on Memetic Algorithm

Electric-heat coupling characteristics of a cogeneration system and the operating mode fixing electricity with heat are main reasons for wind abandonment during heating season in Three North area. To improve wind-power absorption capacity economy system, structure is improved by adding storage device an electric boiler. First, aiming at minimum cost optimal scheduling model including boiler, constructed. Second, according to problem, cultural gene algorithm program compiled simulate calculation example. Finally, through improvement, comparison between conditions before after simulation solutions similar algorithms prove effectiveness proposed scheme. The results show that boiler optimization process not only improves power consumption but also reduces significantly reducing coal unit improving operation. framework has both global evolution population local search which better effect on solution.
