摘要
针对常规分布式能源＂点对点＂供应的局限,以互联网思维为导向,基于产能、用能行为的时空互补性,提出以分布式能源产消者为基本节点,耦合电力和热力融通的区域分布式能源互联网理念。在此基础上,以能源流为纽带,以费用流为目标,构建区域分布式能源互联网拓扑结构、设备配置与运行策略的协同优化数学模型。模型可根据产消者的空间布局、以及对电、热多能源流的动态需求,以最低成本满足所有产消者能源需求为目标,对供给侧分布式能源系统的设备配置、运行策略,以及产消者间能量输送网络进行协同优化。针对典型案例的分析表明,通过引入电力和热力融通,各产消者可通过自助与互助,实现多种能源域内调配,微观层面提升网络整体经济收益,宏观层面对整个电力能源系统亦起到削峰填谷的作用。同时,与常规分布式能源的单体利用模式相比,区域分布式能源互联网不但可获得可观的经济收益,亦能取得一定的节能、减排功效。
To deal with the limitation of single user based distributed energy system, according to the time and space complementarity of both energy supply and demand, while considering the internet thinking, the concept of distributed energy network was proposed. It took the distribute energy prosumer as the basic node, and considered both electricity and heat interchanges among the prosumers. Following which, taking the energy flows as the link and the cost flows as the objective, a collaborative optimization model of network architecture, equipment configuration and operation strategy was developed for the distributed energy network. Based on the spatial locations of the prosumers and the dynamic energy demands, while minimizing total cost of the whole network, the model can determine the optimal system combination and corresponding running strategy of a single equipment, as well as the optimal topology of the energy interchanging network. According to the results of the numerical study, by introducing the electricity and heat interchanges, the distributed energy network may not only improve the economic performance of the whole energy network, but also contribute to the peak shaving of the utility grid. Moreover, compared with the conventional utilization mode of distributed energy resources, besides the satisfied economic performance, the distributed energy network may also result in reasonable energy and environmental benefits.
