Combined ecological and economic benefits of the solar photovoltaic industry in arid sandy ecosystems
摘要： Solar photovoltaic (PV) panels and the vegetation under them consist of a combined system that could provide not only clean electrical power but also an effective preventive measure against wind erosion in sandy ecosystems. Here, by evaluating the effectiveness of the two-tier model, this study focused on the socioeconomic and environmental co-benefits of the solar PV industry in sandy ecosystems. The results showed that the ecosystem services provided by the combined system land were 24 times higher than those provide by natural recovering land. The combined system could achieve $5258.86 (cid:1) 104 in benefits per year, including $3897.48 (cid:1) 104 from electricity and $1361.38 (cid:1) 104 from ecosystem services value. The ecosystem services value could reach 34.93% of the electricity benefits value and become a vital part of the total valuation. The results indicated that electricity benefits and considerable ecosystem value could be generated from the combined systems. These combined systems have great potential for combating desertification and should be considered appropriate public investment projects with high economic and social rates of return in arid areas.

摘要： The solar PV power sector in Spain has been developing at a spectacular rate in recent years. The energy cost and the dependence on fossil fuels can be reduced by improving the efficiency of photovoltaic energy production The performance of a solar radiation conversion system is affected by tilt angle with the horizontal plane. Thus, a photovoltaic array needs to be tilted at the correct angle to maximize its performance. In this paper, we investigate how to determine the optimum tilt angle. This procedure is illustrated for the city of Barcelona (Spain) located at latitude 41o 22' 56'' North and longitude 2o 6'56'' East. The optimal tilt angle varies according the seasons: In Winter (December, January, February) is 56.4, in Spring (March, April, May) is 29.11? in Summer (Jun, July, August) is 13.76? and in Autumn (September, October, November) is 48.14?. Finally, the annual optimum tilt angle for our latitude is 36.87?, with this optimal slope angel, maximum monthly and annual solar radiation is calculated. So, by means of the proposed approach, the energy generation is increased in 10.54% thanks to we are able to benefit from the maximum solar radiation.

摘要： PV power varies with the passing of clouds; these variations can affect power quality and system uniformity. PV system is combining with a storage device to mitigate the variations in power. During the fast movement of clouds causes sudden changes in power. Sudden changes can limit through ramp rate control. In this work employing a ramp rate control with energy storage system is capable of maintaining the system stability. This work is aimed to design a battery-based storage system integration with considered 500 kW solar photovoltaic power plant using ramp rate control method. The control scheme is tested and validated using MATLAB/Simulink environment.
