An improved model to evaluate thermodynamic solar plants with cylindrical parabolic collectors and air turbine engines in open Joule–Brayton cycle

On the performance of CSP oil-cooled plants, with and without heat storage in tanks of molten salts

“…The solar power absorbed from the receiver tube of a collector loop is calculable by the relation [16]:…”

“…The latter is the ratio of the thermal power produced by the solar field at the design point to the thermal power required by the power block at nominal conditions; it is also equal to the ratio of actual total collector area to the nominal total collector area. As a formula, it is defined as: SM ¼ I bn cos iA col Nh col I bn cos iA col N n h col designpoint (16) where N n is the nominal number of collector loops for SM ¼ 1 and N is the actual number of collector loops. Plants without storage need to have a value of SM larger than 1 in order to achieve nominal conditions on the power block during a time interval longer than that obtained if the solar multiple is equal to 1, see Fig.…”

Proposal and study of a balanced hybrid Rankine–Brayton cycle for low-to-moderate temperature solar power plants

“…Brayton cycles have been proposed with moderate-to-high turbine inlet temperatures, i.e. for pure solar power plants [14,15] using air as working fluid, or nuclear power plants [16] using helium and, therefore, considering ideal gas behaviour of the working fluid; at moderate temperature using air and also considering ideal gas [17]; and finally working at moderate-to-low turbine inlet temperatures, considering real gas behaviour and operating close to the critical point (with CO 2 [18,19] and other fluids [1,20]). …”

A review on solar‐assisted gas turbines

“…PV modules convert solar radiation into electricity directly and it is predicted that it will have 11% share of global electricity production by 2050 . Thermal capacity of solar radiation is used for generating electricity indirectly . Based on IEA report, solar thermal electricity (STE) share in global electricity will reach 11% in 2050.…”
