摘要: In this paper, we conduct a techno-economic analysis of 1000 MWe solar tower aided coal-fired power generation system for the whole life cycle. Firstly, output (from coal and thermal energy) under variable direct normal irradiance grid demand are studied. Secondly, financial assessment is performed, including profits losses plant project. Thirdly, sensitivity taken on some external factors that can affect cost or The results indicate project has high with an internal rate return (IRR) 8.7%. addition, effects field cost, purchase agreement (PPA) price electricity, price, interest debt main criteria decrease gradually. Therefore, it better to improve technology first, then look low-interest debts from banks cope reduction PPA electricity increase price. Despite introduction increasing levelized (LCOE), contributes CO2 capture compared case standard plants.
