The invention provides a hydrogen consumption predicted value acquisition method and device. The method comprises the following steps: acquiring historical hydrogen consumption data of a hydrogen consumption device; determining the type of the hydrogen consumption device, and inquiring an auxiliary variable corresponding to the type of the hydrogen consumption device from a preset load variable set; establishing a first mathematical model by using a multielement linear regression algorithm, and acquiring a hydrogen consumption predicted value corresponding to the historical consumption data and the auxiliary variable by using the first mathematical model; filtering out abnormal data and noise data from the historical consumption data; analyzing the average value of all data items in the filtered historical consumption data; and respectively subtracting the average value from all the data items in the historical consumption data, and assigning the computation results to the corresponding data items to obtain the historical consumption data subjected to standardization treatment.
Description
technical field [0001] The present application relates to the technical field of scheduling optimization, and in particular to a method, device and system for obtaining a predicted value of hydrogen consumption. Background technique [0002] In the petrochemical industry, hydrogen is a very important resource, raw material and product. The hydrogen system in the general petrochemical industry includes a hydrogen production device that provides hydrogen, a hydrogen consumption device that consumes hydrogen, and a hydrogen pipeline network that transports hydrogen from the hydrogen production device to the hydrogen consumption device. When the hydrogen production of the hydrogen production device is greater than the hydrogen demand of the hydrogen consumption device, the delivery pressure of the hydrogen pipeline network will increase. Once the pressure exceeds a certain limit, the hydrogen pipeline network must discharge part of the hydrogen to the hydrogen pipeline network. ...
