Analysis of transmission losses of very large-scale photovoltaic power generation systems (VLS-PV) in world desert

VLS-PV systems in desert area are promising in view of rich irradiation and huge land area. But its desert situation, transmission loss may be barrier to realize. This paper is described about estimation of transmission loss without detail irradiation data. Based on power current is in proportion to irradiance, transmission loss is calculated considering change in day, month and year. And rise in temperature is also considered because desert situation. 100 km transmission loss is 8.2 % in Sahara and 5.8 % in Gobi desert. Transmission loss is not so big if it is compared with corrector loss. This result helps preliminary survey of VLS-PV systems in desert areas.
