Abstract

For solving the key limitations of solar–aided power generation system (SAPGS), that is, high cost and unsatisfied solar–to–electricity efficiency (SEE), a novel SAPGS using photovoltaic–driven waste heat recovery cooperating with lignite drying was proposed. Photovoltaics, compression heat pump, and lignite drying were efficiently integrated. Energy and economic analyses were performed. For a 600–MW plant, the proposed SAPGS exhibited an extremely high SEE by 49.87 % using photovoltaic–driven waste heat recovery. The proposed SAPGS achieved 19.5 MW of solar generated electricity and 1.43 % of thermal efficiency lift. Based on the combination of efficient system integration and application of low–cost solar devices, the proposed SAPGS exhibited an outstanding cost of solar–generated electricity (COEs) by 0.160 CNY/kWh, only 16.8 % of that of the conventional SAPGS. The high performances, especially improved SEE and COEs, revealed that the proposed system had potential to solve the key problems of SAPGS.
