Integrated PV and gas-turbine system for satisfying peak-demands

A computer-simulation model of the behaviour of a photovoltaic (PV) gas-turbine hybrid system, with a compressed-air store, is developed in order to evaluate its performance as well as predict the total energy-conversion efficiency and the incurred costs under various operating conditions. This integrated PV and gas-turbine hybrid plant produces approximately 140% more power per unit of fuel consumed compared with corresponding conventional gas-turbine plants. In addition, lower rates of pollutant emissions to the atmosphere per kWh of electricity generated are achieved.
