【Abstract】 In-depth study on the problem of economic optimal configuration of clean renovation of existing district heating system is conducted. The system renovation scheme of industrial waste heat recovery by using low-cost power is given. The operation optimization scheduling of the renovation system is analyzed.Based on the incremental comparison method,a twolayer optimal configuration model of waste heat recovery and storage equipment is proposed. Based on case calculations,the proposed economic optimal configuration model is verified. The results show that compared with the genetic algorithm,the pattern search has the faster convergence speed and higher computational stability when solving the two-layer optimal configuration model. The reasonable configuration of waste heat recovery reserve equipment can obtain considerable comprehensive income in heating period.更多还原
