Abstract
In recent years, in order to solve the environmental pollution problem caused by coal-fired heating in the heating area of north of china, electric heating has received extensive attention and has gradually been developed vigorously. Considering the building characteristics, outdoor temperature, indoor comfort and other factors, the building heat load adjustability model is established, and the heat storage device's load adjustability model considering the current operating status and heat storage capacity of the heat storage device is established, and the two are added together An evaluation model of the adjustability of regenerative electric heating users' load is obtained. This model not only considers the user comfort and the adjustment potential of the building where it is located, but also considers the adjustment potential of the heat storage device, which can more comprehensively and accurately evaluate the user load adjustment potential of thermal storage electric heating.

Summary
In order to solve the environmental pollution problem caused by coal-fired heating in the heating area of north of china, electric heating has received extensive attention and has gradually been developed vigorously[1]. Regenerative electric heating systems, on the one hand, directly provide thermal energy to independent heating pipe networks through electric boilers; on the other hand, they are equipped with certain heat storage devices to store thermal energy during low load periods and release heat energy during peak load periods. Regarding electric heating equipment such as thermal storage electric boilers, due to its own thermal storage device, it can provide a certain load adjustment capability, and most of them only consider the adjustability of the thermal storage device itself, without considering the building adjustment potential. Regenerative electric heating system as a typical adjustable load, its adjustability is mainly manifested in two aspects, one is the adjustability of the heat storage device, and the other is the adjustability of the building's thermal load. This paper considers the building characteristics, outdoor temperature, indoor comfort and other factors to establish the building thermal load adjustability model, considers the current operating state of the thermal storage device and the thermal storage capacity to establish the thermal storage device's load adjustability, and the two are added together to obtain the thermal
