“…In practice, for the pinch point, as it is well known, a null value leads to an infinite surface of economizer then a limit value of 10K is imposed [30]. An effectiveness superheater close to "1" leads to an infinite surface, a maximum value of 0.85 is fixed [31].…”

A thermo-economic simulation model of a hybrid solar gas-turbine (HSGT) power plant with an integrated storage unit has been developed, allowing determination of the thermodynamic and economic performance. Designs were based around two representative industrial gas-turbines: a high efficiency machine and a low temperature machine. In order to examine the trade-offs that must be made, multi-objective thermo-economic analysis was performed, with two conflicting objectives: minimum investment costs and minimum specific carbon dioxide (CO 2 ) emissions. It was shown that with the integration of storage, annual solar shares above 85% can be achieved by HSGT systems. The levelized electricity cost (LEC) for the gas-turbine system as this level of solar integration was similar to that of parabolic trough plants, allowing them to compete directly in the solar power market. At the same time, the water consumption of the gas-turbine system is significantly lower than contemporary steam-cycle based solar thermal power plants.

“…Contemporary solar air receivers can reach sustained outlet temperatures of up to 950 C [10]; however, a design outlet temperature of 800 C has been chosen in order to keep the cost of the solar equipment at reasonable levels. An investigation of the gas-turbine based power cycles by Bhargava [26] suggests that the relative pressure drop within a recuperator should not exceed 3%.

Hybrid solar micro gas-turbines are a promising technology for supplying controllable low-carbon electricity in off-grid regions. A thermoeconomic model of three different hybrid micro gas-turbine power plant layouts has been developed, allowing their environmental and economic performance to be analyzed. In terms of receiver design, it was shown that the pressure drop is a key criterion. However, for recuperated layouts, the combined pressure drop of the recuperator and receiver is more important. In terms of both electricity costs and carbon emissions, the internally-fired recuperated micro gasturbine was shown to be the most promising solution of the three configurations evaluated. Compared to competing diesel generators, the electricity costs from hybrid solar units are between 10% and 43% lower, while specific CO 2 emissions are reduced by 20-35%.
