Abstract

Background and Objectives: Nowadays, water scarcity is a major challenge for our country, Iran. Therefore, storage and Optimal operation of limited resources, including water stored in dams' reservoirs, is one of the issues of interest for researchers in the field of water resources. In this paper, optimization of single-reservoir operation problem is solved by using one of the newest heuristic algorithms, named Charged system search algorithm. Generally, this algorithm is based on the electrostatics laws to determine the quantity of resultant force. Kaveh and Talatahari (2010a) proposed this algorithm for the first time and examined its capabilities for solving engineering problems and sample functions. Results showed that the algorithm has good performance. Therefore, its use for solving engineering optimization problems is recommended. However, a review of literature shows that using of this algorithm is very limited in the field of water resources engineering. Materials and Methods: In this paper, the simple and hydropower operation of Dez reservoir, over 5 and 20 years of operation period are solved using the proposed algorithm. In order to solve these problems, two different formulations are proposed considering water release or storage volume as decision variables of the problem in the first and second formulations, respectively and the results are compared to other available methods. Results: Comparison of the results shows the capability of the proposed algorithm, in which the results of first formulation are better than the second one’ s. In other words, the results of first formulation for solving simple operation problem over 5 and 20 years are reduced by 11. 29% and 16. 69% in comparison with the results of second formulation and also the results are improved by 20. 06% and 37. 66% using the first formulation for solving hydropower problem. Furthermore, the results of the proposed algorithm for solving simple operation problem over 5 and 20 years are reduced by 33. 64% and 74. 97% in comparison with the results of Particle Swarm Optimization algorithm and also the results of using the proposed algorithm for solving hydropower problem are improved by 6. 53% and 41. 48%. In addition, the results of the proposed algorithm for solving simple operation problems over 5 and 20 years are reduced by 7. 79% and 35. 59% in comparison with the results of Genetic Algorithm and also the results of using proposed algorithm for solving hydropower problem are improved by 11. 32% and 67. 43%. Conclusion: Investigating these results with the results obtained by using other existing algorithms indicates a better performance of the Charged system search algorithm for solving the reservoir operation optimization problem. According to these results, the use of this algorithm is recommended for solving other problems in the field of water engineering.
