Overview

Randomized trial evaluates techno-economic performance in solar-assisted micro gas turbine systems, indicating viable design pathways for deployment.

Key Points

  • Assess the techno-economic performance of solar-assisted micro gas turbine systems using detailed modeling and simulations.
  • Detailed off-design model validated against laboratory experiments and operational data.
  • Full-year simulation based on real meteorological data from Pretoria, South Africa.
  • Parametric study covering turbine inlet temperature, dish area, TES characteristics, and component performance.
  • Fuel-to-electric efficiencies of 14–30% observed with levelized costs of electricity ranging from 0.4–0.8 €/kWh.
  • Optimal designs achieved lower electricity costs (down to ≈0.4–0.76 €/kWh) by enhancing turbomachinery efficiency.
  • Lower solar contributions linked to increased dish area but limited economic benefits.
