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

Coupling performance analysis of a solar aided coal-fired power plant

“…The effects of the solar irradiation intensity, the incident angle, the flow rate of thermal oil on the performance of the solar-electricity efficiency for a SACFPP under off-design conditions were also analyzed [19]. Wu concluded that the thermal energy storage system increased both of the annual solar generation and the annual solar-electricity efficiency performance of the SACPG system, and proposed a balance point for thermal energy storage hours and solar field cost [20].…”

Multi‐objective optimization of solar‐aided coal‐fired power generation system under off‐design work conditions

“…Qin et al 18 analyzed four possible configurations of solar preheater (SP), and three typical SP operation strategies, and tried to reveal the optimal scenario of system with the same solar heat input or same solar collector area. Wu et al 21,22 investigated the annual performance of a SAPG system under different sun tracking modes, solar field sizes, thermal energy storage capacities, and load conditions. Hou et al 7,20 evaluated the optimum aperture area of the solar field in their papers, and the optimum aperture area and the lowest levelized electricity costs were given based on the annual performance of a SAPG system.…”

Wu et al 21,22 investigated the annual performance of a SAPG system under different sun tracking modes, solar field sizes, thermal energy storage capacities, and load conditions. Zhao et al 23,24 investigated the evaluation criteria for enhancing the solarcoal hybrid power plant performance, and the optimal solar field size for the hybridization system was provided in their subsequent studies.…”

“…The above researches investigated many typical or novel integration schemes carefully, revealed the advantages of SAPG system comprehensively, 2,[11][12][13][14][15][16][17]23 and tried to find the optimal integration scheme or solar field size for the system. 7,[18][19][20][21][22]24 However, these studies are all always based on one or several certain schemes, then the optimal integration scheme may not be taken into account, besides, the selected optimal objectives (power generation, solar-electric efficiency, or investment) for the solar field size optimization were analyzed separately instead of fully considering their mutual constraints, then the most appropriate design scheme cannot be clearly provided.…”

Thermodynamic analysis of a solar aided coal-fired power plant

“…Solar energy is one of the most potential renewable energies [1][2][3] , which has been studied for decades and some solar thermal power station has been put into commercial operation in America, South Africa etc. [4][5] .…”
