Abstract: The present paper deals with the performance prediction of Concentrated Solar Power plants integrated with cooling energy production. The plant configuration is based on a typical steam Rankine cycle (rated 62.1 MWe). The thermal input is provided by two different solar fields: i) Parabolic Trough Collectors and ii) Central Receiver System with heliostats reflecting on the tower top. In the former case, both north-south and east-west oriented collectors are investigated and compared in the study. A Thermal Energy Storage system allows driving the power block 24-h per day also in periods with low solar irradiation. A steam flow rate extracted from the turbine low stages feeds a set of two-stage absorption chillers, and the produced chilled water is supplied to a district cooling network. A computer code integrating the commercial software Thermoflex and Trnsys has been developed to model and to simulate over 1-year period the solar field and the power block.
