matlab code for optimal location of distributed generation

Abstract

Distributed Generation (DG) is growing rapidly in power systems due to their potential solution for issues, like the deregulation in power system, to meet the power demand and the shortage of transmission capacities. Optimal placement of DG assumes significance that improper allocation of DG sources in power system would not only lead to increased power or energy losses, but can also jeopardize the system operation. Also optimal placement of DG is necessary for the maximization of reliability and stability in power system. In this paper classical grid search algorithm based on successive load flows has been employed to obtain optimal location and size of multiple DG units in radial power system network in order to minimize total active power losses and to improve voltage profile of the system. The proposed method is the extension of single DG placement to the placement of multiple DG units. It is significant because of the fact that with the integration of DG units at various locations, there is more reduction in total power losses and maximum voltage drop in the system is also decreased. The proposed method is tested on 12-bus radial distribution feeder with different sizes of DG source. The obtained results are presented in graphical manner.
