考虑多能协同的工厂综合需求侧响应模型

Industrial park IDR model considering multi-energy cooperation

在能源互联网背景下,分散化的能源市场和能源网络结构使得传统的电力需求侧响应(DR)将逐步向综合需求侧响应(IDR)的方向发展。IDR是能源互联网中实现用户深度参与系统调控、传递能源市场价格信号、参与能源市场的重要切入点,是电力DR理论在能源互联网中的扩展。针对工业园区提出了一种工厂IDR模型,同时将光伏、电储能、冰蓄冷和水蓄冷等分布式资源考虑在内。建立园区内能源系统IDR的物理和数学模型,并将其转换为混合整数线性规划用分支定界法进行求解。仿真结果表明,通过IDR模型的优化,多种能源协同互补,并引导用户制定合理的综合能源利用方案,提高了用户侧的用能效率,减少了用户的用能成本;所提模型在工厂的经济性、灵活性以及系统运行方面均带来了一定的效益。

In the background of energy internet,the decentralized energy market and the energy network structure make traditional DR（Demand Response） gradually develop towards IDR（Integrated Demand Response）. As the expansion of DR in energy internet,IDR is an important entry of users for their participating in the system dispatch,transmiting the price signals of energy market and participating in the energy market. An industrial park IDR model is proposed,which considers various distributed energy sources,such as pbotovohaic power,battery storage,ice storage,water storage,and so on. The physical and mathematical IDR models of industrial park energy system are established and transformed into a mixed integer linear programming,which is solved by the branch and bound method. Simulative results show that,owing to the IDR model optimization,multi-energy cooperation and reasonable user comprehensive energy utilization scheme,the user-side energy consumption efficiency is improved and the user＇s energy consumption cost is reduced;the proposed model brings benefits to industrial park in the aspects of economy,flexibility and system operation.
