  • Value chain optimization in large scale gas network considering elevation and transmission direction

    Value chain optimization in large scale gas network considering elevation and transmission direction

    Sequential linear programming

    The NOP includes both nonlinear terms and integer variables, and in the real-world problem, the network scale is often large. Using general nonlinear programming solvers makes it difficult to solve the NOP within a…
