Background In the technical field of building energy consumption management, for emission reduction and energy saving, a plurality of energy consumption devices such as air conditioners, fans and illumination in a building are required to be subjected to cooperative power adjustment, and a traditional scheme generally distributes a target total power adjustment amount according to rated power or preset priority of each energy consumption device. However, when the power consumption device is actually operated, the real-time operation states of the same type of the power consumption devices are different, part of the power consumption devices can be in a high-fluctuation or high-load operation state, and if the same power adjustment quantity as that of other similar energy consumption devices is distributed to the power consumption devices, the actual power adjustment effect can be greatly fluctuated and the reliability is lower. In order to solve the problems, the prior art collects multi-source data including the running state of equipment, energy consumption prediction is performed by using a machine learning model, and a power adjustment control strategy is generated by using reinforcement learning. However, the reinforcement learning reward mechanism in the prior art is designed according to whether the actual energy consumption is lower than or approaches to the predicted value to continuously improve, so when the reinforcement learning reward mechanism is applied to a scene where a given target total power adjustment amount needs to be quickly achieved, a few devices which are easy to adjust and respond quickly may be repeatedly acted, so that part of the devices are overloaded, the situations of misalignment of power adjustment amount distribution and large power fluctuation are easy to occur, and the total power adjustment amount cannot be achieved due to the characteristics of reinforcement learning per se. Therefore, the prior art cannot ensure that the target total power adjustment amount is achieved, and the situations of misalignment of power adjustment amount distribution and large power fluctuation are easy to occur, so that the stability of the cooperative power adjustment of the multi-energy consumption equipment is greatly reduced.
