基于多源热泵协同优化的区域综合能源系统经济调度OA

To explore the synergistic optimization effect of electric heat pump and gas heat pump,a regional comprehensive energy system(RIES)economic dispatch method for the coordinated operation of multi-source heat pump systems is proposed.Firstly,a comparative exposition of the technical characteristics of electric heat pump and gas heat pump is conducted.Based on the energy hub,various energy flows of the system under the multi energy complementary operating conditions of electric heat pump and gas heat pump are analyzed.Secondly,based on the price advantages of electricity and gas energy,electric heat pump is used for electric cold energy coupling during peak electricity periods,and gas cooling is replaced by gas heat pump during peak electricity prices to improve the peak valley characteristics and operating costs of the system's electricity load.Finally,a collaborative optimization dispatch model for electric heat pump and gas heat pump is established with the optimal system cost,and solved by using CPLEX software.The calculation example shows that the coordinated operation of electric heat pump and gas heat pump can fully leverage the advantages to reduce the operating cost of the system and optimize the interaction power fluctuation of the interconnection line.Moreover,the proposed method has good environmental benefits.
