Real-time optimisation of natural gas pipelines intransient conditions is a challenging problem. Manypipeline systems are, however, only mildly non-linear even in large transients such as compressorstation (CS) shutdown or startup. A dynamic,receding horizon optimisation problem is defined,where the free response prediction of the pipelineis obtained from a pipeline simulator and theoptimal values of the decision variables areobtained solving an approximate QuadraticProgramming (QP)problem where the cost function isthe energy consumption of the CSs. The problem isextended with discrete decision variables, theshutdown/start-up commands of CSs. A Mixed LogicalDynamical (MLD) system is defined, but the resultingMixed Integer QP problem is shown to be very high-dimensional. Instead, a sequence of QP problems isdefined resulting in an optimisation problem withconsiderably smaller dimension.The receding horizon optimisation is tested in asimulation environment and comparison with data froma true natural gas pipeline shows 5 to 8 % savingsin compressor energy consumption.

Paperback, [PU: VDM Verlag Dr. Mueller E.K.], Real-time optimisation of natural gas pipelines in transient conditions is a challenging problem. Many pipeline systems are, however, only mildly non- linear even in large transients such as compressor station (CS) shutdown or startup. A dynamic, receding horizon optimisation problem is defined, where the free response prediction of the pipeline is obtained from a pipeline simulator and the optimal values of the decision variables are obtained solving an approximate Quadratic Programming (QP)problem where the cost function is the energy consumption of the CSs. The problem is extended with discrete decision variables, the shutdown/start-up commands of CSs. A Mixed Logical Dynamical (MLD) system is defined, but the resulting Mixed Integer QP problem is shown to be very high- dimensional. Instead, a sequence of QP problems is defined resulting in an optimisation problem with considerably smaller dimension. The receding horizon optimisation is tested in a simulation environment and comparison with data from a true natural gas pipeline shows 5 to 8 % savings in compressor energy consumption., Technology: General Issues<
