Today, energy is one of the most important and strategic issues in different societies and it has become clear to everyone that we should not have to depend on a fossil fuel source to supply the electricity required because it is not an endless resource, and more importantly has many environmental hazards. Therefore, the use of renewable resources has been seriously considered in advanced societies and subsequently in third world countries, so that much investment has been made to build renewable power plants. Fortunately, Iran has excellent renewable resources and has the potential to generate the electricity it needs, but yet much of that potential has not been exploited.
In this study, a mathematical model for designing electricity supply chain using wind and solar energy simultaneously is presented. This model considers the variability of wind speed and solar radiation and consequently the uncertainty in the level of electricity generated by them at different times. In this research, reliability and, to some extent, sustainability concepts, have been considered to study the various dimensions of the subject. This model seeks to locate combined wind, solar power plants, converter stations and their capacity determination, deciding to build new transmission lines or increase the capacity of existing lines and also the optimal allocation of electricity to demand points.
Our model is implemented on a real case after validation with numerical examples. This case study was carried out with Iranian data, which results, as expected, indicate a significant reduction in variable costs and pollutants compared to the existing fossil fuel system.
