| Summary: | Consumer demands of natural gas as energy sources is expected to be increase.
Gas distributor companies have to ensure gas distribution is going properly. Gas
was distributed by pipeline network which consists of nodes that represent points
of consumer, suppliers and junctions connected by pipe, valve and regulator. Assuming
the gas flow is in steady-state and the system model consists of set non-linear
continuous equations. The iterative method is widely used to solving non-linear
equation system problem such as Newton and Broyden method. However, many
iterative methods has a drawback which is depend on initial approximation in order
to get convergence solution. Metaheuristic method such as Differential Evolution
Algorithm is able to combined to get a close approximation solution that continue as
initial approximation. Based on testing with both method Broyden and Hybrid using
simple network pipelines has given good result that reached percentage of success
is 100% form several tests. But, in using complex pipelines network problem the
Hybrid method significantly has given better results than only use Broyden method
of success percentage and convergence iteration total, respectively is 83.34% and
2732 iteration. Whereas, only using Broyden method has the results respectively is
60% and 3840 iteration. |
