The electricity structure across the globe has changed from the vertically integrated to horizontally integrated where technologies like distributed Generators, electric vehicle, renewables energy are integrated into the distribution network with a view of providing voltage upgrade, reducing power loss and to relieve transmission and distribution congestion. This is further transformed into smart grid through the use of computational intelligence techniques. In this paper, the optimal power analysis and performance evaluation of Basiri distribution network with and without DG integration was carried out. A detail modeling of the network was carried out in Matlab environment as well as the codes for the Genetic Algorithm (GA). The performance analysis was conducted using the voltage level at various bus bars as an index. Different scenarios were considered and the simulations were carried out based on the integration of different capacities of DG located manually and optimally. The steady state results show that the voltage levels in some locations were below the standard voltage level. This is addressed using genetic Algorithm to placed the DG at optimal point so as to minimize voltage drop. The GA results was able to improved the voltage level to the standard level and also to determine whether the network is capable of accommodating more DG then determining the penetration level.
