Thus, by classifying the operating states of the electricity usage units into a critical operating state, a medium operating state, and a minor operating state, the operating states are provided in a reasonable order, facilitating the supply of electricity to the electricity usage units according to this order, such as: the electricity unit is the cutting device and the cutting device is performing the cutting operation, which is necessary in the subsequent production, the cutting device is in an important operating state, whereas the cutting operation is inconsequential in the subsequent production, the cutting device is in a secondary operating state.
Optionally, the corresponding relationship between the running state and the operation executed by the electricity consumption unit is a fixed corresponding relationship set by a factory or a user. In this way, it is convenient to determine the operation state of the electricity consumption unit directly according to the correspondence relationship, for example: the electricity utilization units execute transmission operation, and the transmission operation is an essential link in production, so that the corresponding electricity utilization units are in an important running state.

Therefore, the priority is conveniently determined according to the importance degree of the running state, the importance degree of the running state and the priority are set to be in a proportional relation, when the importance degree of the running state is higher, the priority is higher, and when the importance degree of the opposite running state is lower, the priority is lower, so that the relevance between the importance degree of the running state and the priority is enhanced, the priority is conveniently determined according to the importance degree of the running state, and the power can be supplied to a power utilization unit with high importance degree of the running state preferentially.
Optionally, the priority comprises: high priority, medium priority, and low priority. Thus, by classifying the priorities into a high priority, a medium priority and a low priority, the priorities are given a reasonable order, facilitating the supply of electricity units according to this order.
Optionally, the power units with high rated power are preferentially supplied with power in the same priority. Therefore, under the condition of the same priority, the power resource can be reasonably allocated according to the rated power, namely, the power is preferentially supplied to the power utilization unit with high rated power, so that the power can be reasonably allocated in the power utilization peak period, the power utilization unit can be ensured to stably operate, and the power allocation efficiency of the power grid is improved.

Therefore, after the high-priority running state and the low-priority running state of the power utilization unit are determined, the power utilization unit in the medium-priority running state is determined, so that the power allocation has a reasonable order, the power allocation process is more stable, and the power allocation efficiency is improved.
Optionally, controlling the power to power the electricity usage unit includes: the power of the electricity consumption unit is adjusted.

Therefore, when the power of part of the electricity utilization units is reduced, the power of the power grid can supply power to other electricity utilization units, so that the power can be controlled to supply power to the electricity utilization units according to the power of the electricity utilization units through adjustment of the power of the electricity utilization units, the power of the electricity utilization units is always at the rated power of the electricity utilization units, the electricity utilization units are ensured to operate under the rated power of the electricity utilization units, and the normal operation of the electricity utilization units is ensured.
