Abstract
Distributed generations (DGs) have grown rapidly in the power system because of their fast technological developments as well as the economic and environmental issues of the conventional electricity generations. DGs can improve power system reliability, reduce cost of electricity and lessen emissions as well as enhance the voltage stability of distribution system. However, in order to improve voltage stability as well as minimize power losses for practical power systems, it is important to locate DG in the appropriate place. Various methods have been developed. The particular CPF method has been proven effective in determining DG placement. In this paper, a new method to determine an optimal DG allocation is presented which is based on the modal analysis that involves eigenvalue and eigenvectors techniques. Numerical example on a 34-bus distribution network is given to illustrate the effectiveness of the proposed method. This paper also compares the effectiveness of the new method to the CPF method.
