In recent years, the demand of electric power generation has increased significantly. Electrical distribution systems are progressively featured with multi types of Distributed Generation (DG) units to meet the sustainable energy requirements, improve voltage profile, and minimize energy losses. The aim of this work was to improve voltage profile and to reduce the power losses by optimal placing and sizing of multiple DGs, grouped in three types according to their capability in generating active and reactive powers, using iterative method. The load-flow method was used to simulate the test system i.e., IEEE-33 bus radial distribution system, using MATLAB programming. A notable improvement in voltage profile and reduction in active and reactive power losses of 69.66% and 64.14%, respectively, were achieved in comparison to the system without DGs.
