For proper and efficient utilization of wind power, the prediction of wind speed is very important. Wind is one of the main sources of energy in the world, but the wind turbines have a lack of reliability, continuity and homogeneity in power production. On the other hand, sudden changes of wind speed, lead to risk for wind turbine units health. Therefore, the prediction of wind speed for turbin...

The wind is one of the most important and affecting phenomena and is known as one of the significant clean resources of energy. Apart from other atmospheric parameters, the wind has complex behavior and intermittent characteristics. Local phenomena can be accompanied by the wind, which is strong, non-predicted, and damaging.  Weather radars are capable of detecting and displaying storm-related ...

Nowadays, optimal placement of wind turbines in a wind farm is one of the major concerns of the wind farm designers. This paper concentrates on the optimal placement of wind turbines in a wind farm. The optimal placement of wind turbines has been carried out to maximize the output energy and minimize the investment cost of cable, road and wind turbines. For this purpose, Firstly, it should be d...

Abstract: In the last decade, the amount of distributed generation connected to the distribution network is increasing. The presence of distributed generation resources in distribution systems has a great influence on its behavior and it is necessary to consider the impact of these resources on the distribution network design. In this study, Optimal Coordinated Voltage Control (OCVC) using wind...

Problem: Droughts in Zabul have cause the erosion of human habitats, especially in areas exposed to sand accumulation. Creating an optimal urban form can be a way to counteract its destructive effects.Methodology: in this paper, the research method is based on the partial air flow simulation method and the city form survey. The goal is to find the most optimal form of residential buildings to r...
