Effects of Load Models and Load Growth in Distribution System in Presence of Distributed Generator

The power distribution systems always need special attention for its planning and control. The distribution systems must be persistently adjustable to increasing load demand with satisfying the voltage range and without defying highest current conveying potential of the conductors. Properly planned distribution systems can lower capital investment, subtract system power losses and to provide improved quality of powers to consumers. This paper reviewed the works done by researchers previously on the effects of load models and load growth on system power loss and voltage profile. An IEEE 13-bus radial electrical distribution test network is considered and simulated. Then, a study is carried out for the impact of DG in distribution system planning such as line loading with load growth, system power loss, voltage profile, need of new substation or up-gradation of existing substation and investment on transmission and distribution lines expansion.
