摘要

经济和环境因素在海水淡化技术从传统能源向替代能源的转变中发挥着至关重要的作用，太阳能处于领先地位。本文研究了使用三种不同类型的电力系统：国家电网、独立（离网）光伏系统和并网（上网）光伏系统为100 地中海城市利比亚的黎波里的m³/天反渗透海水淡化厂。产品水的成本分析显示，有利于将并网光伏作为电源，可以显著节约成本。此外，本文还研究了利率对采出水成本的影响。本文的另一个发现是，考虑到低太阳辐照度的时间，离网光伏系统的规模过大对总发电量的利用水平产生了影响。

Techno-economic comparison of three different types of powering systems

Economic and environmental factors play a crucial role in the transitioning of water desalination technologies from conventional energy sources to alternative sources, solar energy being in the forefront. This paper investigates the technical and economic merits of using three different types of powering systems: the National Electric Grid (Grid), a Standalone (Off-Grid) Photovoltaic (PV) System, and a Grid Connected (On-Grid) PV System to power a 100 m³/day reverse osmosis seawater desalination plant in the Mediterranean city of Tripoli-Libya. The cost analysis of product water showed significant savings in favour of On-Grid PV as a power source. Also, in this paper, the effect of interest rate on the cost of the water produced was studied. An additional finding of this paper was the impact of Off-Grid PV system oversizing to account for times of low solar irradiance on the level of utilization of the total electricity produced.
