W δ (τ) changes dynamically over time and is affected by the cumulative impact of historical adjustment behaviors.

[0063] The time scale adjustment factor of the flexible load device is determined by integrating the sum of the short-term adjustment factor, the medium-term adjustment factor and the long-term adjustment factor under the adjustment time, which is specifically shown in the following formula:

[0071] The calculation formula for user inappropriate cost is: Where: ζ represents the user's sensitivity coefficient to inappropriateness, which is used to measure the user's tolerance to inappropriateness caused by load regulation (such as reduced comfort, broken usage habits, etc.). For highly sensitive users (such as the elderly, children, or places with high environmental requirements), ζ is usually higher, and for industrial loads or non-critical equipment, ζ is usually lower; represents the adjustment fatigue of the mth user;
