Abstract

Concentrating solar power (CSP) is considered as a comparatively economical, more efficient, and large capacity type of renewable energy technology. However, CSP generation is found restricted only to high solar radiation belt and installed where high direct normal irradiance is available. This paper examines the viability of the adoption of the CSP system in a low sun belt region with a lower direct normal irradiance (DNI). Various critical analyses and plant economics have been evaluated with a lesser DNI state. The obtained results out of the designed system, subjected to low DNI are not found below par, but comparable to some extent with the performance results of such CSP plants at a higher DNI. The analysis indicates that incorporation of the thermal energy storage reduces the levelized cost of energy (LCOE) and augments the plant capacity factor. The capacity factor, the plant efficiency, and the LCOE are found to be 32.50%, 17.56%, and 0.1952 $/kWh, respectively.

太阳黑带地区集中式太阳能发电系统的可行性

摘要

集中式太阳能（CSP）被认为是一种相对经济，更高效和大容量的可再生能源技术。但是，发现CSP的产生仅限于高太阳辐射带，并且安装在可提供高直接法向辐照度的地方。本文研究了在太阳直射辐照度（DNI）较低的低太阳带地区采用CSP系统的可行性。已使用较低的DNI状态评估了各种关键分析和工厂经济学。在低DNI的情况下，从设计的系统中获得的结果未低于同等水平，但在较高DNI的情况下，可以与此类CSP工厂的性能结果相媲美。分析表明，并入热能存储可降低平均能源成本（LCOE），并增加工厂的产能因子。容量因子，电厂效率和LCOE分别为32.50％，17.56％和0.1952 $ / kWh。
