Control strategies applied in the HYSOL demonstrator: A simulation-based evaluation

HYSOL project was born under the idea of designing a new hybrid concentrating solar power plant concept fully based on renewable energies and able to provide stable power. Within this project, one of the main activities is the development of a demonstrator facility to evaluate experimentally the gas turbine heat recovery and its transference to a molten-salt storage system. This paper describes the main control loops proposed to maintain the facility at different operating points to study both nominal and off-design states.
