A Thermoeconomic Study of Hybrid Solar Gas-Turbine Power Plants
2011 (English)In: Proceedings of the International SolarPACES Conference 2011, Granada, 2011Conference paper (Refereed)
A dynamic simulation model of a hybrid solar gas-turbine power plant has been developed, allowing determination of its thermodynamic and economic performance. Designs were based around two representative 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 CO2 emissions. At current fuel prices, gas-turbine solarisation was shown to result in only a small increase in levelised electricity costs at moderate solar shares. In the future, with higher fuel prices and carbon taxes, it was shown that electricity from hybrid solar gas-turbines could be cheaper than from fossil-only gas-turbines.
