Integrated Solar Combined Cycle (ISCC) power plants have gained popularity among the thermal power plants. Traditional ISCC power plants use Direct Steam Generation (DSG) approach. However, with the DSG method, the ISCC plant’s overall thermal efficiency does not increase significantly due to variations in the availability of solar energy.
Li et al. suggested a new solar-driven power generation system including RC and ORCs. The system efficiency was found to be 15.6% with the hot-side temperature at 523 K and the cold-side temperature at 293 K. Moreover, they stated that the main exergy destruction occurred in the solar collectors (about 80%).
Current planned solar operated cogeneration energy system comprises of a steam Rankine cycle (RC), user heat, and organic cycle Rankine (ORC) with the aid of solar energy to generate combined heating and power.
Integrating solar field with the bottom cycle, the output power of the bottom cycle will be increased with the rising of solar energy input [ 19 ]. While, for a selected steam turbine, the maximal output power is constant, thus the penetration of solar energy integrated into the combined cycle is always restricted [ 20 ].
The suggested solar-operated tri-generation cycle system is designed to harness energy from the sun and simultaneously produce power, heating, and cooling, in three different cycles as illustrated in Fig. 1 and Ts diagram is illustrated in Fig. 2.
A solar collector can be considered as a heat exchanger for converting solar energy to thermal energy of the working fluid. Generally, there are two kinds of solar-ORC systems: direct and indirect. With the indirect solar-ORC system, solar energy is absorbed by a solar working fluid that circulates in the solar collector.
