Impact of distributed generation on the Nigerian power network

Distributed generations (DG) are being installed at increasing rates, both in developed and developing countries. The number of DG connected to the distribution system could have a significant impact on power operation. This paper presents case study investigating grid-connected Nigerian network terms bus voltages losses. results showed that without DG, some voltage magnitudes test were outside permissible limit 0.95pu≤Vi≤1.05p.u. However, with connected, improved allowable values. active loss was reduced by 12.03% from 85.60MW 75.30MW. In this way, becomes more efficient secured.
