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

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.
