建筑空调系统基于用能柔性参与电力市场研究综述
Research on building air conditioning systems for participating in electricity market based on energy flexibility:A review
摘要:
近年来,为解决能源问题并实现碳中和目标,全球范围内的可再生能源发电量迅速增长。然而,可再生能源发电的间歇性也对电网平衡提出了更大的挑战。建筑空调系统可通过柔性用能有效缓解智能电网平衡的压力。本文分析了建筑空调系统正在及有望参与的电力市场类型,以及参与不同类型市场对建筑空调柔性控制的要求,而后总结了空调系统实施柔性用能的控制策略及控制中遇到的问题和解决方法,最后分析了柔性用能容量的约束及提升方法,并对建筑节能与柔性用能进行了比较和思考,以期为空调系统通过柔性用能参与各类型电力市场的深入研究、探索提供参考。
Abstract:
In recent years,to address energy issues and achieve carbon neutrality goals,the global volume of renewable electricity generation has rapidly increased.However,the intermittency of renewable energy generation poses greater challenges to the stability of the electrical grid.Building air conditioning systems can alleviate the pressure on smart grid balance through flexible energy use.This paper analyses the types of electricity markets in which building air conditioning systems are currently and potentially involved,as well as the requirements of flexible control of air conditioning systems for participating in different types of markets.This paper then summarizes the control methods of air conditioning systems for implementing flexible energy use,the problems encountered in control,and corresponding solutions.Finally,this paper analyses the limitations and enhancement methods of flexible energy use capacity and presents a comparison on building energy conservation and flexible energy use.In summary,this paper aims to provide a reference for the in-depth study and exploration of air conditioning systems participating in various types of electricity markets through flexible energy use.
