Network Analysis of the Federal Capital Territory Distribution System of Nigeria for Future Integration of Distributed Energy System

The present electricity supply to the Nigerian capital city is short of expectation, hence, it is affecting the social, economic, and security of the territory. This paper presents a network analysis of the Federal Capital Territory distribution network of Nigeria. The analysis was conducted for four scenarios using the DIgSILENT software. The analysis considered power supply to the distribution network from two-generation sources. From the results obtained, the best voltage profile was obtained when the distribution network was supplied from two-generation sources. A network loss of 2S.35MW was obtained for the scenario with two generation sources while 35. S3 MW and 2S.97 MW were obtained when the power supply was from one of the two sources each. In terms of the frequency, the system was stable when the generation was from two sources while for single generation sources, the system was unstable. The network analysis provides a basis for identifying ways of improving the reliability of power supply to the distribution network and for future integration of distributed energy systems.
