چکیده انگلیسی
PSO or CA estimates different values for the network inlet flow rates. Using each of these estimated values, both boundary conditions will be known at the network inlets and discretized flow equations can be linearized. These linear flow equations will be solved for the network inlet nodes. This procedure will be continued for the next nodes until reaching network outlets. Then the differences of calculated and actual network outlet pressures will be defined as a cost function or error. Eventually, these algorithms will obtain the optimum inlet flow rates which minimize the cost function. Thus, the calculated pressures and flow rates at different gas network nodes which are obtained by using these optimum inlet flow rates will be the true values. Our proposed approach reduces the complexity of solving network transient flow equations with the mentioned boundary conditions while simulation results confirm its accuracy and efficiency.
