主 题:Dimension reduction group search optimization large-scale cooling energy system many-objective optimization
摘 要:Large-scale cooling energy system has developed well in the past ***,its optimization is still a problem to be tackled due to the nonlinearity and large scale of existing *** the scale of problems without oversimplifying the actual system model is a big challenge *** paper proposes a dimension reduction-based many-objective optimization(DRMO)method to solve an accurate nonlinear model of a practical large-scale cooling energy *** the first stage,many-objective and many-variable of the large system are pre-processed to reduce the overall scale of the optimization *** relationships between many objectives are analyzed to find a few representative *** control variables are extracted to reduce the dimension of variables and the number of equality *** the second stage,the manyobjective group search optimization(GSO)method is used to solve the low-dimensional nonlinear model,and a Pareto-front is *** the final stage,candidate solutions along the Paretofront are graded on many-objective levels of system *** candidate solution with the highest average utility value is selected as the best running *** are carried out on a 619-node-614-branch cooling system,and results show the ability of the proposed method in solving large-scale system operation problems.
