In this paper, the prioritization and weighting of different methods of using renewable energy, as well as the feasibility of using renewable energy in the management of sports venues in the water and electricity industry of east Azerbaijan province, have been discussed. The D-number theory method has been used to prioritize different methods of using renewable energy. The results of gathering information from experts in this field, show that using solar energy with a weight of 0.5345 is the best method for producing electrical energy in sports and welfare venues. Also, the use of wind energy with a weight of 0.5183 and the use of water energy with a weight of 0.5126 are in the next ranks, respectively. The indicators used in ranking factors include total costs, energy efficiency and compatibility with environmental conditions. Based on the results of the feasibility study and the available findings, it can be seen that the total cost of using renewable energy in the sports and welfare venues of East Azerbaijan Province is equal to 10093.4 million Rials. Also, the interest return rate of the investment is equal to 19.43%. Therefore, using solar energy as a source of electricity production has technical and economic justification.

Although the development of science and technology in the present era has increased human satisfaction from life, it has caused the problems such as environmental pollution and increased demand for energy carriers, especially fossil fuels. Considering that fossil fuels can be exhausted, the most suitable solutions to address the consequences are the use of renewable energy sources to generate electricity. In this paper, using the Particle Cumulative Optimization (PSO) algorithm, we have tried to design an optimal photovoltaic and winding model to supply the power of an area in such a way that the electrical charge generated by this system has the reliable capability and economically viable.
