The percent increase in energy production with corresponding increase in hub-height for wind energy conversion system (WECS) from different manufacturers was compared in this study. It was seen that an increase of 10m in hub-height from 40 to 50m resulted in an increase of 3.17% in energy...

The air conditioner should control the building sensible and latent load properly in order to provide the indoor comfort conditions. The conventional mechanical vapor compression system usually controls the latent load by the process of condensation of water vapor in which air is cooled below...

This study presents a PV–diesel hybrid power system with battery backup for a village being fed with diesel generated electricity to displace part of the diesel by solar. The hourly solar radiation data measured at the site along with PV modules mounted on fixed foundations, four generators of...

The study presents the design and economic assessment of a wind farm of 20 MW installed capacity, located in the Eastern region of Saudi Arabia. The wind farm is designed using 2 MW size wind machines from Vestas at a hub-height of 60 m using specialized WindFarm software. The land area...

A wind–pv–diesel hybrid power system has been designed for a village in Saudi Arabia which is presently powered by a diesel power plant consisting of eight diesel generating sets of 1,120 kW each. The study found a wind–pv–diesel hybrid power system with 35% renewable energy...

The power sector in the Kingdom of Saudi Arabia is undergoing the restructuring process. Moreover, during the last decade the Kingdom has witnessed a phenomenal growth in the load demand, consequently a huge amount of generation is added to the electric utilities to meet the load. Up to now only...

The objective of this study was to achieve higher efficiency of a PV system while reducing of the cost of energy generation. Concentration photovoltaics was employed in the present case as it uses low cost reflectors to enhance the efficiency of the PV system and simultaneously reduces the cost...
