Improving Power Availability of the National Power System Using Solar-Based Enhanced Distributed Generation Technology

In this paper, the method for connecting a solar-based enhanced distributed generation technology to the national utility grid was developed, which is expected to improve the poor state of electric power supply in Nigeria. All countries in the world need an available power supply to improve its economy. The power sector is an important sector that requires good funding for the constant availability of electricity for its citizens. Nigeria has not yet met the population requirement as far as power availability is concerned. The utilization of solar photovoltaic generated electricity will improve the nation’s power supply and ensure power availability in the country. The study aims to improve the power availability of the national power system using solar-based enhanced distributed generation technology. The photovoltaic system generated 250MW solar power which was injected into the national utility grid. The 250MW was gotten from five locations in the country as each location generated 50MW to the national utility grid. The performance of power output from the photovoltaic array as well as the power output from the inverter into the grid and losses that arose from the solar photovoltaic system was analysed. The simulation carried out in this work was done with PVsys and AutoCAD software. From the analysis done using PVsys software, to analyse the annual performance of the photovoltaic system for the five locations, the system gave a percentage performance of 79.1percent for the photovoltaic system and the total energy the arrays will inject into the grid annually is 387.765GWh.
