As far as I know, there is not any component(type) regarding Fresnel solar power plant in trnsys, So you should write your own code for Fresnel solar collector and with other components required simulate the power plant.

Mark Stetz

Sorry for the late reply. If you are going to write code for TRNSYS for a Fresnel collector, you have to take into account the decrease in collector efficiency due to the self-shading of the adjacent linear elements. The efficiency falls off as the f-number decreases. Low f numbers are required for high-temperature concentration, which works against Fresnel systems. It's worse for circular collectors. I worked out the math for this over 25 years ago but now can't find my results. I also built a small prototype using multiple 25 mm mirror segments on a wood frame just as proof of concept. Let us know how the TRNSYS modeling goes.
