The power outage in Ado Ekiti is disturbing and has produced a negative effect on the life and economy of the people. This study presents investigation of power supply challenges in Ado-Ekiti Low Voltage Distribution network with the specific focus on the development of an algorithm for its improved performance. In this work, voltage quality problem and its cause was investigated. Load flow of the Llow Voltage (LV) network was carried out using impedance modeling with the aid of MATLAB/SIMULINK. Results obtained from the analysis were applied to develop algorithm for improved performance of the LV network while measures for improved LV performance were formulated from the developed algorithm. The analysis indicated that the voltage drop on the LV network is within the range (0.87p.u-0.94p.u). Voltage deviation is completely outside the permissible range of 6%.
