Abstract: This paper presents a study on a so-called linear Fresnel reflector (LFR). It is a linear solar concentrator system that can be connected to a combined cycle power plant (CCPP) to improve the performance of the resulting plant, called an integrated solar combined cycle. First, the modelling of the system is addressed, based on a physical approach, with an optical part on the one hand, and a thermal part on the other hand, using a moving-boundary technique. Then, the system behaviour is studied in simulation under solar radiation fluctuations. Eventually, considering that the superheated steam produced by the LFR is to be injected into a CCPP, a linear quadratic approach is proposed for its control. Finally, simulation results confirm that this control law is appropriate to regulate the output steam enthalpy.
