Abstract: A system and method for controlling delivery of gas, including a gas pipeline network having at least one gas production plant, at least one gas receipt facility of a customer, a plurality of pipeline segments, and a plurality of control elements, one or more controllers, and one or more processors. The hydraulic feasibility of providing an increased flow rate of the gas to the gas receipt facility of the customer is determined using a linearized pressure drop model. A latent demand of the customer for the gas is estimated using a latent demand model. Based on the hydraulic feasibility and the latent demand, a new gas flow request rate from the customer is received. A network flow solution is calculated based on the new gas flow request rate. The network flow solution is associated with control element setpoints used by a controller to control one or more control elements.

Abstract: A method of controlling a fuel supply network, the method comprising: defining a directed acyclic graph comprising a set of fuel pathways; defining a set of reportable fuel pathways as a set of linear equations, the set of reportable fuel pathways comprising a subset of the set of fuel pathways; solving the set of linear equations to determine designated pathway quantities for the set of reportable fuel pathways; determining one or more throughput setpoint values for one or more edges in the directed acyclic graph based on the designated pathway quantities for one or more reportable fuel pathways associated with said one or more edges; controlling one or more control elements of the processes associated with the one or more edges based on the determined throughput setpoint values for the respective one or more edges.
