摘要
为提高区域综合能源系统的经济效益,提出了考虑需求侧响应的含储能的区域综合能源系统运行优化模型。首先建立包含储能、分布式能源、微型燃气轮机、燃气锅炉、蓄热槽等区域综合能源系统模型和可转移负荷、可削减负荷的模型。然后以系统的总运行成本最小为目标,构建区域综合能源系统运行优化模型;最后采用cplex求解器进行求解,通过算例验证。结果表明,需求侧响应和储能对提高系统经济性具有积极影响,可转移负荷、可削减负荷、储能在系统的调度中起到了移峰填谷的作用,需求侧响应的引入能有效降低系统总运行成本和峰谷差,验证了模型和方法的有效性。
An optimization model of the regional integrated energy system with energy storage considering demand response was proposed to improve its economic benefit.Firstly,energy storage,distributed energy,micro gas turbine,gas boiler,regenerator,and load that could be shifted and curtailed in the regional integrated energy system were modeled.Then,the operation optimization model was built with the minimum total operating cost of the system as the objective function.Finally,the model was verified by the case study solved by Cplex.The results show that demand response and energy storage have a positive impact on improving the system economy.Load that could be shifted and curtailed plays a role of peak shifting and valley filling in system scheduling.Demand response can effectively reduce the total operating cost and peak-valley difference of the system.The validity of the model and method is proved.
