Modeling and Simulation of Regional Integrated Energy System Operation Based on Refined Thermal Equipment Model
Abstract
Regional integrated energy system (RIES) is the main terminal form of access to ubiquitous power Internet of things in the future, and its energy supply form is mainly electricity and heat. On the basis of studying the equipment structure and operation mechanism of the main elements of thermodynamic system, such as cogeneration unit, ground source heat pump, building heat load, thermodynamic pipe network and electro-thermal coupling equipment, the steady-state operation refined model of each element is established in this paper, and based on this, an operation state analysis model of electro-thermal coupling RIES is studied, and then it is validated by a 48 thermal node-14 power node-multi energy flow coupling system case study. The model and simulation method can be used to analyze the system operation status of RIES, and can calculate the internal operation status of various grid-connected energy equipment. It lays a foundation for studying the system and equipment characteristics, understanding the operation status, and formulating operation control strategy.
