基于“电为核心”现代能源体系的内涵和建设目标，提出“电为核心”的现代能源体系主要包括能源基地建设、综合能源服务体系构建、能源基地与智慧城市的供需互动。能源基地要充分耦合风光水火储多种能源，发挥不同能源形式在时空特性、能源特性上的互补，建议重点以风光火储一体化、风光水储一体化、风光氢储一体化这3种典型模式建设。为提高终端用能效率，文章分别给出了工业领域、建筑领域、交通领域这3个领域综合能源服务模式应用实例。在供给侧大力推进能源基地建设，在需求侧推进综合能源服务为基础的智慧能源，以工业互联网技术为支撑，以商业模式创新为保障，实现供需高效、高频互动，是提升电力系统安全性和灵活性，保证供需平衡，建设“电为核心”的现代能源体系的必然选择。

Based on the connotation and construction goal of "electricity as the core" modern energy system, this paper proposes that the modern energy system with "electricity as the core" mainly includes the construction of energy base, the construction of comprehensive energy service system, and the interaction between supply and demand between energy base and smart city. The energy base should be fully coupled with wind, water and heat storage, and give full play to the complementarity of different energy forms in space-time characteristics and energy characteristics. It is suggested that the construction of three typical models should be focused on the integration of wind- photovoltaic - thermal -storage, wind- photovoltaic- hydroelectric- storage and wind- photovoltaic -hydrogen-storage. In order to improve the efficiency of terminal energy consumption, this paper gives three application examples of integrated energy service mode in the industrial field, the construction field and the transportation field.Vigorously promoting the construction of energy base on the supply side, promoting smart energy based on comprehensive energy services on the demand side, and realizing the efficient and high-frequency interaction between supply and demand with the support of industrial Internet technology and the guarantee of business model innovation are the inevitable choices for improving the security and flexibility of power system, ensuring the balance of supply and demand, and building a modern energy system with "electricity as the core" .
