Assessment of Wind and Solar Energy Potential at ADUSTECH-Wudil for Hybrid Electricity Generation Using Weibull Distribution and Samani Model

Abstract

Intermittent nature of electricity supply in Nigeria is not only affecting social-
economic sector, also educational sector. It affects activities such as lecture
presentation, laboratory practical etc. Also, the inconsistency in the cost of fuel is
making it difficult to conduct some laboratory practical in some Nigerian
Universities. This work analyzed the wind and solar data of Aliko Dangote
University of Science and Technology (ADUSTECH), Wudil (formerly known as
Kano University of Science and Technology, Wudil (KUST-Wudil)), to assess their
potentials in complementing the electricity supply from National grid. The
methods employed are Weibull probability distribution and Samani Model for
wind and solar assessment, respectively. Data from Nigerian Meteorological
Agency (NIMET) for three years (2018 to 2020) is used in the study. The wind
power density obtained based on Weibull distribution parameters is 308.06 W/m2
in March and 465.94 W/m2 in November, with minimal error of 0.09 on a scale of
RMSE. In the Samani model it is observed that an estimated solar radiation of
about 10.5 MJ/m2/day in March and about 27 MJ/m2/day in July. According to
National Renewable Energy Laboratory (NREL) the site is above class 3 for wind
power generation, thus recommended for hybrid system to complement the supply
from national grid and to complement each other.
