One of the biggest causes of worldwide environmental pollution is conventional fossil fuel-based electricity generation. The need for cleaner and more sustainable energy sources to produce power is growing as a result of
The solar power plant consists of several subsystems, including the heliostats field, central receiver, and the mechanical cycle Environmental parameters such as the intensity of the
The power output can be maximized using innovative approaches in collector and chimney design which are appropriate to the local geographical conditions. The critical design parameters of the SCPP are the collector area, height, diameter, and slope; the chimney height; and the turbine pressure drop, which affect the efficiency of the plant.
The increase in solar radiation improves the temperature gradient developed in the collector and pressure gradient in the collector chimney transition region as reported by Huang et al. (Huang et al. 2007 ). This results in the improvement of the power of the plant.
The cooling tower approach declines non-linearly and strongly as the ambient temperature increased, indicating that a typical approach of 15 °C may significantly underestimate the power output of the solar power plant.
Fig. 13 shows influence of DNI and ambient temperature on the performance of the solar power plant. The mass flow rate of the oil entering the IHX keeps constant by adjusting HTF mass flow fraction when the solar irradiation is low, and the power output of the power system can be maintained at a high level with the buffering of TES.
In this type of STPPs, solar-to-electricity efficiencies are around 25%, since the power block is limited and its thermal performance is in a range between 35% and 38% and the solar field efficiency is around 65%.
Solar thermal power plants for electricity production include, at least, two main systems: the solar field and the power block. Regarding this last one, the particular thermodynamic cycle layout and the working fluid employed, have a decisive influence in the plant performance. In turn, this selection depends on the solar technology employed.
