Author(s): Emami, Mohammad; Nazif, Sara; Mousavi, Sayed-Farhad; Karami, Hojat; Daccache, Andre | Abstract: The continuous growing demand for water, prolonged periods of drought, and climatic uncertainties attributed mainly to climate change mean surface water reservoirs more than ever need be managed efficiently. Several optimization algorithms have been developed optimize multi-reservoir syste...

The mid-long term optimal operation of hydropower station is a nonlinear combinatorial optimization problem with strong constraint. This paper eliminates the problem constraints by introducing penalty function and solving this problem with DE algorithm, simultaneously, it proposes a few improvements according to the disadvantages of DE algorithm: adopt the scheme which generates differential ve...

In the present study an evolutionary based optimization algorithm Differential Evolution (DE) is applied to a case study of Bisalpur project, Rajasthan, India. The objective of DE based planning model is to determine suitable cropping pattern which yields maximum net benefits. Ten different strategies (variations) of DE are analyzed with various population sizes, crossover constants and weighti...

During the rebuilding of a gas reservoir, repeated “strong injection and mining” processes change seepage capacities water. Hence, accurately determining laws water in storage reservoir is crucial. In this study, standard relative permeability test was conducted with one-dimensional core. Additionally, mining simulation experiment two-dimensional plate. The results show that curve obtained by c...
