As an electric energy alternative technology

regenerative electric heating will affect the safe operation of the distribution network in the process of application

with people’s attention to distributed energy resources and the development of electric heating related technologies

the research of electric heating is becoming more and more important. In order to fully exploit the adjustable potential of regenerative electric heating in the distribution network

the analysis is carried out from the two levels of regenerative electric heating unit and cluster. Firstly

the quantitative indicator of adjustable potential is proposed

including capacity

charge and discharge power

energy storage status

up-regulation capacity and down-adjustment capacity. Then the mathematical model of the adjustable potential indicators of regenerative electric heating units is analyzed. And then fuzzy clustering algorithm is used to cluster electric heating users based on the energy consumption characteristics of users

and the upward adjustment capacity and downward adjustment capacity of electric heating clusters are analyzed. Finally

the mathematical model is verified by specific examples.
