Model for Optimal Sizing of a Wind Energy Conversion System for Green-Mobile Applications

Abstract

The goal of the green-mobile technology is to attain negligible anthropogenic emissions of carbon dioxide (from the GSM base station generators), which constitute by far the largest part of the emissions of greenhouse gases, thereby making the environment much more friendly and safe. This study established the effect of altitude on the output power of wind turbine generators, and proposed a robust model to account for this effect is proposed for optimal sizing of a wind energy conversion system (WECS) for green-mobile applications. The proposed model implementation using a perfectly fitted polynomial expression derived from the manufacturer's power profile. Adjustment of the observed mean wind speed data to a 75 m lattice tower of a mobile station indicates that the proposed model can be effectively powered by mean wind speed for three different locations (Abuja, Benin City, and Katsina) in Nigeria. Analysis indicates that WECS, with its turbine is placed at an altitude of 100 m, loses approximately 1% of its output power.
