Prioritizing the Construction of a Hydropower Plant on Water Supply Pipelines Using Multi-Criteria Decision-Making Methods
Abstract
The construction of the hydropower plant on the water pipelines using the excess pressure and replacement of PAT instead of the pressure reducing valve (PRV) due to positive effects such as renewable energy, the proper dispersion of water supply pipelines in different regions and short production time are considered. On the other hand, the prioritization of the construction of the power plant on the water pipelines involves various factors, which require multi-criteria decision-making methods. In this research, the water pipelines managed by the water and wastewater company of Ilam province, including six positions, taking into account five indicators, electricity production, construction costs, distance from the place of use, distance from the main road and ease of operation using multi-criteria methods (including: hierarchical analysis, network analysis, simple weighting, VIKOR and similarity to ideal option and economic analysis). The results indicated that the entrance to the Station 1 of the Ilam Dam (with an annual production capacity of 982800 kWh, the construction cost of 1218 million Rials, with a benefit-cost ratio of 3.7 and unit cost of 407 Rials per kW) is the best alternative for the production of hydro-electrical energy.
