英文摘要	Affected by the shortage of water resources and land degradation, the sustainable development of agriculture in more and more arid areas will face serious obstacles. The combinations of agricultural photovoltaic, water transportation and irrigation systems are considered as a potential choice to solve above problem. This study aims to investigate the competitiveness of various system configurations to transport water from water resource to agricultural irrigation systems driven by the output power of agricultural photovoltaic. Including the levelized cost of electricity and net present value, a comprehensive techno-economic assessment model is proposed to analyze the agricultural photovoltaic and irrigation systems in arid areas for six scenarios. The applicability of the proposed model in managing regional water and renewable energy nexus systems was tested through application to a real-world case study in the Gansu province, China. Assuming that the baseline transportation distance is 50 km, the results show that exporting water to farmland through electric water trucks shows the best economic performance with the net present value of 13.71 MU$, and every 10 km increase in the transportation distance can decrease the net present value by 1.32 MU$. An important finding is that when the transportation distance was greater than 100 km, pipeline transportation mode was more economical than electric water truck transportation mode. Finally, a sensitivity analysis was carried out to analyze the electricity and water prices, farmland size, photovoltaic efficiency on the economic performance of these systems. Results show that only when the electricity price was greater than 0.08 $/kWh, pipeline transport mode yielded positive benefits, and every 0.1$/m3 increase in the water price can increase the net present value by 0.2 MU$.
