A Modified Differential Evolution Algorithm to Optimize the Design of Gas Transmission Network
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 10
Abstract
A modified Differential Evolution (DE) is used in optimization of a gas transmission network. The goal is to reduce the annual operating and maintenance costs by optimizing many network parameters such as the number of compressors, lengths and diameters of the pipeline segments, flow rate in each pipeline segment, discharge and suction pressures at each compressor. The design must satisfy several constraints,. The values of some parameters are dependent on other parameters, which increases the complexity of the network, using the standard DE technique. Hence, A modification strategy is needed to improve the searching for the global optimum values. The modified DE has been successfully applied to this complex and non-linear problem and needed a very shorter computational time to converge to the optimal solution. Previously, this problem was tackled using many techniques including nonlinear programming and DE techniques on a certain network configuration and setting. However, their optimal solutions did not satisfy all constraints, and the costs were still high compared to the results obtained by the modified DE algorithm. In addition, the proposed modified algorithm can be used for any network configuration. The modified Differential Evolution algorithm is presented here and compared with the previously used ones.
