摘要
能源利用技术的发展、信息技术的进步以及其深度的融合催生出了新的能源利用体系——能源互联网。能源互联网对多种能源系统进行协调优化,接纳大规模可再生能源,并提高能源利用效率。规划是能源互联网从理论到工程实践的第一步,只有在先进、合理的能源互联网规划的理论支持下,能源互联网的工程实践才能有效实施。该文首先基于已有的能源互联网的相关研究,按照"源–网–荷"的结构对能源互联网进行划分,其次介绍了规划建模所需的多种能源的负荷预测、描述多能源转化的数学模型和多能流潮流模型。基于此,从基本的规划模型、能源生产环节的规划、源–网环节的协同规划、能源消费环节的规划、规划模型的求解方法这几个方面对能源互联网的规划进行了分析、探讨。最后对能源互联网的规划的未来研究方向进行了展望。
The development of energy utilization technology, the improvement of information communication technology and the deep integration of both techniques have led to the birth of new energy utilization system-energy internet. Multiple energy systems are coordinated optimally by energy internet to accommodate large-scale renewable energy and improve energy utilization efficiency. Planning is the first step for energy internet from theory to engineering practice. Only in the support of advanced and feasible energy internet planning theory, the engineering practice of energy internet can be carried out smoothly. Energy internet was firstly divided into generation-gird-load 3 parts on the basis of existing related research to the structure of energy internet in this paper. Then the load forecast of multiple energy, the model of multi-energy conversion and energy flow model of multi-energy system were illustrated for the need of planning. Based on them, the analysis and investigation of planning for energy internet was reviewed in basic planning model, planning of multi-energy generations, collaborative planning of multi-energy generations and transmissions, planning of multi-energy consumptions and the solutions to planning model. Finally, the potential research topics on planning of energy internet was proposed.
