Abstract：In recent years,the installed capacity of wind power in China has a great growth.However,wind cannot be fully consumed because of the inflexibility of power system.The wind resources are abundant while the wind curtailment is serious especially in the"Three North"region of China.As an effective solution,the combined power and heat integrated energy system can significantly improve the system flexibility and wind power consumption by coordinating the operation of power and heat systems.This paper firstly introduces the framework of combined power and heat integrated energy system and analyses the ideas of improving wind power consumption.From the three perspectives including system's supply-side,storage-side and load-side,we then introduce the flexible resources that can be utilized to promote the consumption of wind power and improve the system's regulating ability.Next,we discuss the operation mechanism,measures,and applications of the two dispatch strategies,which are the combined power and heat integrated demand-response dispatch strategy and the combined power and heat integrated source-load-storage coordinated scheduling strategy respectively.Finally,we conclude the state-of-art on optimal scheduling of the combined power and heat integrated energy system to promote the consumption of wind power and propose an outlook on how to realize the consumption of wind power under the new energy system structure with a high proportion of new energy supply and electrified loads and the diversified complexity of elements in the future.
