Micro gas turbine central receiver systems offer advantages which could improve the techno-economic viability of the next generation of concentrating solar power plants. This dissertation investigates the optimal optical configurations of this relatively young technology. A fundamental study of heliostat optics identifies principal optical components and develops methods to more accurately and efficiently describe the flux distribution of a heliostat beam. The methods are applied in a techno-economic sensitivity study which indicates that the technology has alternative parameter sensitivities to conventional systems. The collective findings suggest that small heliostats offer a significant optical performance advantage which may lead to a lower levelised cost of energy.
