| dc.description.abstract | This thesis focuses on the performance evaluation of 620MW photovoltaic (PV) systems integrated into an islanded Nigeria electric power grid. Electricity supply in Nigeria is abysmal and the effects on the economy and quality of life of Nigerians. To grow Nigeria GDP by 7%, additional generation capacity of 119,200MW is needed by 2030 while contributing mitigating of the effects of greenhouse gases, deploying renewable energy sources must be considered in generation planning. According to African-EU Renewable Energy Corporation Programme the installed capacity of off grid generation in Nigeria is about 14 GW, slightly above the grid capacity of about 10 GW. This work reviews various related literatures. It carries out load flow studies and Contingency analysis, using a set of possible contingency scenarios, of an islanded segment of the Nigeria Electric network namely Afam Power Substation to Yenogoa Transmission Substation without utility scale PV system integrated. The studies are done also with 500MW PV system integrated at Afam Power Station and 120MW at Gbarain Power Station. The data used were valid upto the year 2021. This work utilizes PowerWorld Simulator for these analyses. The results show a reasonable degree of stability was achieved when there was loss of generation. For example, with Afam Generation station open, system violations went from 14 (without PV) to 3 (with PV). Finally, the results for levelized cost of electricity (LCoE) for combined cycle gas turbines and PV systems show that the LCoE for PV systems was 0.1273 $/kWh, which is still less than LCoE of 0.0970 $/kWh The results also show that such hybrid generation planning can provide a high degree of redundancy in our fragile network. | |
