Biobjective programming for operation strategy of CCHP plants

Aiming at the operation strategy of CCHP plants, establishes a biobjective programming model to minimize both the annual running cost and the annual primary energy consumption. Presents the reasonable operation modes and schemes according to the annual cooling, heating and power load. Explores the influence of the change of economic weight and energy consumption weight on total objective function. Analyses the influence of the natural gas cost and the hourly rate of purchased electric power on the operation strategy.
