LP model uses line-pack to optimize gas pipeline operation

The compressibility of natural gas allows the use of line pack to compensate for fluctuations of gas demand. On the basis of forecast consumption, a linear-programming model can yield a plan for optimal flow rate of a gas pipeline.This model allows demand fluctuation to be satisfied with a minimum of energy consumption. Using this model requires the definition of maximum storage capacity as well as a permanent control algorithm of its evolution over time.System configuration Click here to enlarge imageTransporting natural gas by pipeline from producing fields to customers requires a given number of compressor stations (CS) to maintain the pressure necessary for gas flow (Fig. 1).Compress...
