Abstract

Background and Objectives: Optimal utilization of water resources systems and appropriate formulation rules and policies for the exploitation of reservoirs have been considered by water resource experts in recent years and extensive research has been carried out. Although much progress has been made in terms of problem-solving strategies and computational tools, the problem of optimizing the operation of a multi-reservoir systems due to the effect of upstream storage capacities on downstream inputs, is so complicated. Routine optimization methods due to high constraints, discontinuous space and non-linear nature of water resource management issues are not a good tool for solving such problems. For this reason, the metaheuristic optimization algorithms have been considered by researchers. Materials and Methods: In this research, the performance of the GA and PSO in solving the problem of optimizing the operation of a multi-reservoir system including Bostan and Golestan dams located in Gorgan-Rood watershed has been studied and compared. The survey of the input to the two dam reservoirs in the year 2014-2015 shows that due to the climate change, the annual input to the Bostan and Golestan dams has decreased by 17% and 60%, respectively. Genetic algorithm is a parallel and guided search based on the theory of evolution. The operators of the GA algorithm include selection, crossover and mutation that are used to make up the next generation, respectively. In PSO optimization algorithm, based on the birds and fishes movements, a number of particles are propagated in the search space and the value of the objective function is calculated in proportion to the position of each particle. Then the new particle position is calculated using the combination of current particle locations and the best place previously used. Results: The best answer of the PSO algorithm during the 10 runs is 909. 95 and the worst is equal to 930. 53, while the best answer of the GA algorithm during the 10 runs is 931. 17 and the worst was 957. 32. The comparison of the mean of the answers also show that the PSO algorithm has a 3% advantage over GA. Conclusion: The PSO algorithm has a better performance than GA, so that the PSO algorithm with a Reliability of 49. 38% has a better performance than the GA algorithm with a Reliability of 48. 44%.
