Optimization method for total operation energy consumption of air compression system

The invention relates to an optimization method for total operation energy consumption of an air compression system. The optimization method comprises the following steps: constructing a substance density and substance viscosity expression required by a digital twin model of the air compression system; modeling is conducted on a pipe network part in the air compression system, specifically, a single pipe model is established firstly, a data-oriented programming method is adopted, the single pipe model is regarded as a structural body for storing data, and then the structural body and a performance function are decoupled; based on the constructed single-tube model, constructing a compressor structural body and a performance function; and constructing an air compression system model, obtaining optimal operation parameters based on the air compression system model, and controlling the operation of the air compression system. Compared with the prior art, parallel optimization is carried out on pipe network pressu
