Analysis of Solar PV and Wind Power Penetration into Nigeria Electricity System

There is an imminent electricity demand/supply crisis in Nigeria. Many citizens of the country only have access to few hours of electricity daily. However, the renewable energy (RE) and fossil fuel resources in this country is enormous but these are underutilized for electricity generation. In this study, the used of solar PV and wind power plants to solve Nigeria electricity problem will be investigated. The aim of this research is to determine the maximum penetrable capacity of solar PV and wind power with/without critical excess electricity production (CEEP). The simultaneous integration of solar PV and wind power into the electricity network from the generation side is also considered. From the analysis, solar PV and wind power maximum integration into the current electricity system without CEEP are 12,000MW and 11,000 MW respectively. Economic analysis results indicate that integration solar PV is slightly cheaper compared to the use of onshore wind power plant.
