摘　　要：随着新能源发电、电动汽车、微电网、冷热电三联供、大型电热锅炉、地源热泵等大规模接入电力系统,电力系统变成了含冷/热/电等多种用能形态的能源互联网系统,也使电力系统安全稳定运行的同时面临电网侧与用户侧的双重影响,为此提出一种能源互联网背景下多态用能与电网间安全稳定的协调控制框架。首先,简介了电力系统的多态用能,并分析了其特征;其次,从正常态和故障态两个角度构建了多态用能与电网间安全稳定的控制目标;最后,设计了多态用能与电网间安全稳定的协调控制框架,以期为高渗透率新能源消纳提供可行思路。With the integration of large-scale new energy resources,EYs, microgrids, CCHPs,large electric heating boilers and ground-source heat pump in to power system,it has been converted to be a meshed multi-energy system with the setup for cooling, heating, and electricity. Since power system^s stability can be affected by grid and user sides, a frame work design of coordinated control for multi-energy’s utilization and grid’s stability and security under the scope of energy internet is proposed in this paper. Firstly, this paper introduces mulit-energy utilization in the power system, and investigates its characteristics. Secondly, the control objects for multi-energy’s utilization and grid’s security and reliability were constructed from the aspects of normal and contingency conditions. Lastly, a framework is designed for multi-energy’s utilization and grid’s stability and security, and provides a viable scheme for the utilization of high-penetration new energy.
