AI Technical Summary
Existing methods for assessing the adjustable potential of cooling loads fail to fully consider the thermal energy storage characteristics of cooling loads, the elasticity of user temperature perception, and dynamic response characteristics. This leads to assessment results that deviate from reality, making it impossible to accurately determine the duration and potential of cooling loads in grid dispatch, thus affecting grid safety and stability.
A refined model of cold load electro-thermal coupling considering the user comfort elasticity range is constructed. Data is collected through smart meters and temperature sensors, equivalent thermal parameter differential equations are established, and constraint envelopes characterizing the dynamic change of adjustable potential over time are generated. The data are then aggregated according to spatial dimension and time scale to form a dynamic potential map, which is uploaded to the power grid dispatch system.
It enables accurate assessment and dynamic display of the adjustable potential of cold load, improves the grid's utilization efficiency and safety stability of distributed flexible resources, and enhances the grid's proactive defense capabilities against power fluctuations and faults.
