    Abstract:

    With the integration of large-scale new energy resources, EVs, 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.
