摘要
为探究电、气热泵协同优化效果,提出多源热泵协同运行的区域综合能源系统(RIES)经济调度方法.首先,对电、气热泵技术特性进行对比阐述,并基于能量枢纽对电、气热泵多能互补运行工况下系统各类能量流进行分析;其次,根据电、气能源价格优势,在谷电时段利用电热泵进行电-冷能源耦合供能,在电价高峰时段通过气热泵进行气-冷替代供能,改善系统用电负荷峰谷特性与降低运行成本;最后,以系统成本最优建立电、气热泵协同优化调度模型,采用CPLEX软件进行求解.算例表明:电、气热泵协同运行能够充分发挥二者优势,降低系统运行成本的同时优化联络线交互功率波动,并且所提出的方法具有良好的环保效益.
Abstract
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.
