“…3,4 Then the new technology, the synergetic power generation of traditional fossil fuel and renewable energy, emerges as the time require, and provides the possibility for the renewable energy utilization at low cost, high efficiency, and wild scope through the equipment sharing, and the good opportunity for the flexible operation by alternating between different energy resources. The most immediate way is to reduce the fossil fuels use, and at the same time increase the proportion of renewable energy.…”

“…But the reality is that abundant fossil fuels with high energy densities and low prices have contributed to their almost absolute dominance throughout the 20th century, 1 albeit they also have significantly contributed to the global carbon dioxide (CO 2 ) emissions, 2 while the relatively higher cost, lower efficiency, and intermittent characteristics are the main obstacles for the massive utilization of renewable energy resources. 3,4 Then the new technology, the synergetic power generation of traditional fossil fuel and renewable energy, emerges as the time require, and provides the possibility for the renewable energy utilization at low cost, high efficiency, and wild scope through the equipment sharing, and the good opportunity for the flexible operation by alternating between different energy resources. 5 Among many renewable energy resources is the concentrated solar power (CSP), which is considered as an ideal technology to hybridize with other energy technologies for power generation, for example, coal, natural gas, biofuels, geothermal, photovoltaics, or wind.…”

Solar‐aided coal‐fired power generation (SAPG) has been attracting more and more attentions in recent years. However, the multi‐objective optimization of SAPG system considering off‐design work conditions has not been fully studied. In this paper, a general system integration optimization method (GIOM) has been developed for integration schemes optimization, and Nondominated Sorting Genetic Algorithm‐II (NSGA‐II) algorithm is used for multi‐objective optimization of SAPG system. As a case study, a SAPG system that refers to a real 600 MWe supercritical coal‐fired power plant is optimized based on a typical day. By simultaneous optimization of both initial investment (P) and solar net electric generation (Esolar), the solar subsystem design schemes are optimized as Pareto optimal set. At last, to maximum Esolar/P, the final design scheme is selected from the Pareto optimal set, whose Esolar and P are 237.6 MWh and 113.5 M$, respectively. The results show that, the final design scheme is a heliostat field with instantaneous optical efficiency of 63.24% at the design point, the receiver power rating is 133 MWt, the tower height is 136.6 m, and distances of successive rows of the three zones are 13.6, 17.7, and 24.5 m, respectively. A larger or smaller size of solar subsystem is considered to be uneconomical.

Abstract:In this paper, we conduct a techno-economic analysis of a 1000 MWe solar tower aided coal-fired power generation system for the whole life cycle. Firstly, the power output (from coal and solar thermal energy) under variable direct normal irradiance and grid demand are studied. Secondly, a financial assessment is performed, including profits and losses of the plant project. Thirdly, sensitivity analysis is taken on some external factors that can affect the cost or profits and losses of the plant project. The results indicate that the project has high profits with an internal rate of return (IRR) of 8.7%. In addition, the effects of solar tower field cost, power purchase agreement (PPA) price of solar thermal electricity, coal price, and the interest rate of debt on the main criteria decrease gradually. Therefore, it is better to improve solar tower technology first, and then look for low-interest debts from banks to cope with the reduction of PPA price of solar thermal electricity and the increase of coal price. Despite the introduction of solar tower field increasing levelized cost of electricity (LCOE), it contributes to the reduction of CO 2 capture cost compared to the case of standard coal-fired power plants.
