Co-allocation of solar field and thermal energy storage for CSP
Abstract. Concentrating solar power (CSP) plants produce electricity without any pollutant emission, which is one of the most attractive alternatives to fossil fuels. The thermal energy storage (TES) benefits CSP plants to produce electricity during temporary weather transients and peak-load demand hours.
