[32] compared the parabolic trough and Linear Fresnel
collectors in ISCCSs. They reached a conclusion that the use of linear receivers reduces the costs of
electricity generation and the best method to merge solar power into these plants is steam generation.
In this paper, full repowering of MSPP in Iran is evaluated. Since full repowering is among the best
choices for MSPP, this method is used to increase efficiency in this SPP. Regarding the fact that
Isfahan is geographically located in a suitable place to install solar power plants or solar repowering;
merging solar energy into the mentioned power plant is also investigated.
