摘要
多能互补综合能源系统(Integrated Energy System,IES)是提高分布式新能源渗透率和增强终端能源消费灵活性的重要手段,针对现有技术在多能系统对外能量特性建模和多系统交互策略方面研究的不足,文章提出了一种基于虚拟储能的综合能源系统用能协调控制方法,基于多代理技术构建楼宇-代理商-配网三层能量交互架构,以描述系统对外特性的虚拟储能模型为交互接口,量化分析管控多楼宇和并网储能、微燃机等多能分布式资源的代理商的虚拟储能。在此基础上,按照系统空间范围扩大递进分析,构建基于多代理的综合能源系统用能协调控制策略,该策略能够根据决策目标最大化利用以配电网为核心的楼宇、园区等各层级综合能源系统的资源,尽可能实现自治运行。
Integrated energy system is an important means to improve the permeability of distributed new energy and enhance the flexibility of terminal energy consumption.In view of the shortcomings of existing technologies in the modeling of external energy characteristics of multi-energy systems and the research of multi-system interaction strategies,this paper proposes a coordinated control method of integrated energy system based on virtual energy storage,and constructs three-layer energy architecture in terms of building layer,agent layer and distribution network layer based on multi-agent technology.Based on the interactive architecture,the virtual energy storage model describing the external characteristics of the system is used as the interactive interface to quantitatively analyze and control the virtual energy storage of agents which regulates multi energy distributed resources,such as multi buildings,grid connected energy storage,micro gas turbine,etc.Furthermore,according to the system spatial scope,the hierarchical expansion and progressive analysis are carried out to build a multi-agent based integrated energy system coordinated control strategy.The decision-making goal is to maximize the resource endowment of the building,park and other comprehensive energy systems so as to meet the energy demand as much as possible and realize autonomous operation.
