Resumen
[EN]Small-scale hybrid parabolic dish concentrated solar power systems are a promising
option to obtain distributed electricity. During the day, solar energy is used to produce electricity,
and the absence of sunlight can be overwhelmed with fuel combustion. This study presents a
thermo-economic survey for a hybridized power plant in different regions of Spain, considering
the local climatic conditions. The developed model considers the instant solar irradiance and
ambient temperature dynamically, providing an estimation of the power output, the associated
fuel consumption, and the most relevant pollutant emissions linked to combustion. Hybrid and
combustion-only operating modes at selected geographical locations in Spain (with different latitudes,
mean solar irradiances, and meteorological conditions) are analyzed. The levelized cost of electricity
indicator is estimated as a function of investment, interest rate, maintenance, and fuel consumption
actual costs in Spain. Values of about 124 e/MWhe are feasible. Fuel consumption and emissions
in hybrid operation can be reduced above 30% with respect to those of the same turbine working
in a pure combustion mode. This model shows the potential of hybrid solar dishes to become
cost-competitive against non-renewable technologies from the point of view of costs and reduction in
gas emission levels in regions with high solar radiation and low water resources.
