In this embodiment, the production equipment includes intermediate equipment and finished product equipment; finished product equipment refers to production equipment from which finished products are derived, and intermediate equipment refers to other production equipment in the production chain in addition to finished product equipment. Because each production device in the production link has a bearing relation, a semi-finished product produced by the current intermediate device by using raw materials is the raw material of the next-stage intermediate device, and a semi-finished product produced by the previous-stage intermediate device of the finished device is the raw material of the finished device; that is, the storage amount of the semi-finished product of the current intermediate device is the storage amount of the raw material of the next-stage intermediate device.
Specifically, in the process of calculating the target operating power of each production device at each time in each production cycle in this embodiment, the production amount and the storage amount of the semi-finished product at each time in the production cycle of each intermediate device are calculated according to the actual production scale and the storage amount of the raw materials, and then the target operating power of the finished product device at each time is calculated according to the planned production amount and the storage amount of the semi-finished product of the upper-stage intermediate device corresponding to the finished product device.

it should be noted that the actual production scale includes: semi-finished product storage capacity and/or finished product storage capacity.
Specifically, due to the limitation of factors such as the production site and the equipment scale, the number of semi-finished products stored in the production link is limited, and the specific constraint conditions are as follows:
wherein, Cl maxThe maximum capacity that can be stored in the production chain for the semi-finished product.
In addition, due to uncertainty of order transaction time and order quantity, limitations of traffic conditions and transportation capacity, finished products produced by finished product equipment cannot be immediately transported out of a factory, but are stored in a warehouse. And because the warehouse can not be expanded in a short time, the quantity of finished products produced by the finished product equipment is limited by the finished product storage capacity of the warehouse, namely the quantity of the stored finished products is less than or equal to the maximum value of the finished product storage capacity of the warehouse, and the specific constraint conditions are as follows:
wherein the content of the first and second substances,

On the basis of the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and specifically, a process of calculating a target operating power of a finished product device at each time according to a planned production amount and a storage amount of a semi-finished product of an upper-stage intermediate device corresponding to the finished product device specifically includes:

Therefore, the process for obtaining the target operating power of the finished product equipment provided by the embodiment fully considers the production condition of the finished product equipment in the production link, so that the actual production requirement can be met when the finished product equipment operates according to the calculated target operating power.
As a preferred embodiment, controlling each production device to operate at each time according to each corresponding target operating power specifically includes:

wherein k is the number of operating production facilities M; k is the total number of production devices M;
representing the power rating of the production facility M.
It should be noted that, when the production facility is a single production facility with non-adjustable power, the target operation power of the production facility is the rated power, that is,
the embodiment provides various methods for adjusting the operating power of the production equipment, and the method can be suitable for various types of production equipment and is convenient for actual operation execution.
On the basis of the foregoing embodiments, the present embodiment further describes and optimizes the technical solution, and specifically, after controlling each production device to operate according to each corresponding target operating power at each time, the method further includes:

It should be noted that, according to the electricity utilization policy of the incentive demand response in China, the electricity price in the demand response period is cheaper than that in the non-demand response period. Therefore, in actual operation, the production capacity of each production device at different moments can be different by setting the operating power of each production device at each moment, so that on the premise of meeting the planned production capacity and the actual production demand, the production capacity in the demand response time period and the operating power of the production device are reduced, the production capacity in the non-demand response time period and the operating power of the production device are increased, the response of the industrial power users to the demand is realized, the economic compensation of the demand response is obtained, and the effect of saving the electricity charges is achieved. Specifically, in the case of considering the demand response, the objective function of the required electricity rate when the actual production demand is completed is as follows:
