Annual economic performance of a solar-aided 600 MW coal-fired power generation system under different tracking modes, aperture areas, and storage capacities

摘要

The solar-aided coal-fired power generation (SACPG) system is proven to be an effective way to use solar energy. In this work, a 600 MW SACPG system using solar parabolic trough technology is simulated based on hourly meteorological data. Solar field is used to preheat feedwater to replace high-pressure extraction steam of the original coal-fired unit.
