区域综合能源系统规划研究综述

Review on Research of Regional Integrated Energy System Planning

区域综合能源系统作为能源互联网的重要物理载体,对提高综合能源利用效率、消纳可再生能源、保障供能安全可靠及节能减排具有重要意义。对区域综合能源系统进行合理有效规划,要打破行业壁垒,从技术、政策、地域等多方面实现突破。文中对区域综合能源系统规划中的多能耦合理论、负荷预测方法、技术经济性分析、规划优化建模与求解等关键问题进行了系统地总结归纳,对各问题所涉及的国内外研究现状、存在问题及难点进行了分析与概括。结合目前最新研究进展,概括了全面涵盖区域综合能源系统源、网、荷、储等环节的通用性能流模型、规划模型及求解流程,并对未来的研究方向进行了展望。

As the physical carrier of Energy Internet, regional integrated energy system(RIES) has become an important role for improving comprehensive energy utilization efficiency, renewable energy consumption, energy supply reliability, energy saving and emission reduction. The planning of RIES encounters many challenges, such as industry boundaries, policies, regional differences and techniques. In this paper, the key problems of RIES planning are discussed including multi-energy coupling, load forecasting, technical economy and optimization modelling. The domestic and foreign relative researches are summarized systematically. Based on the latest research progress, a universal energy flow model, planning model and solution process covering the source, network, load and storage of district integrated energy system are summarized, and the future research directions are prospected.
