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

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

“…Hu et al 2,11 reported the energy advantages and exergy advantages of a SAPG system based on a typical 500 MWe brown coal-fired power generation unit. Li et al 16 carried out the coupling performance analysis of a SAPG system by the proposed all-condition mechanism model. Yang et al 13 demonstrated the advantages of SAPG technology based on a 200 MWe coal-fired thermal power plant in terms of solar to power efficiency, specific fuel and steam consumption rates, under various integration scenarios.…”

“…Zhai et al 15 carried out the life cycle assessment of solar-aided coal-fired power system, based on the grey relation analysis, they found that the SAPG system with thermal storage system was better than that of the coal-fired power system and the SAPG system without thermal storage system. Li et al 16 carried out the coupling performance analysis of a SAPG system by the proposed all-condition mechanism model. Zhang et al 17 analyzed the performance of a SAPG system by two integration schemes based on a practical 660 MWe supercritical power generating unit and the results showed that the standard coal consumption rate of power generation could be decreased by more than 17 g/kWh.…”

“…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.…”

Off-design thermodynamic performances of a solar tower aided coal-fired power plant for different solar multiples with thermal energy storage

“…Yang et al considered a 200 MWe coal-fired unit as an example and investigated four different integration schemes, and the results show that the solar thermal to power efficiency can be over 36% for the solar heat at 260 ℃ [9]. Then, the thermal performance [6,[10][11][12][13], economic performance [14,15] and off-design performance [5,6,16] different modes of solar aided coal-fired power generation system through theoretical calculations [23]. These studies indicated that SACP system is a promising way for the large scale utilisation of solar energy with high efficiency and can reduce the fossil fuel load in the coal-fired power system.…”

Thermal performance of different integration schemes for a solar tower aided coal-fired power system

“…Air pollution and global warming have been posing a serious threat to human health and the environment, which is mainly caused by the use of fossil fuel. In China, over 70% of the electrical demand is met by coal-fired power generation stations [1,2], which contributes a large proportion of greenhouse gas and pollution emissions. In this matter, the Chinese government has taken effective emergency measures in order to address these problems.…”
