Effects of Distributed Generation on power loss, loadability and stability

Abstract

Distributed generation (DG) can provide solutions to many energy supply system problems. While DG is demonstrating its benefits to the power system, the extent varies with different placement strategies. In this paper, a static model for proton exchange membrane fuel cell (PEMFC) DG system model in power flow analysis is proposed. The overall effects of adding DG to the modified IEEE 14 bus test case are studied. Different DG placements are compared in terms of power loss, loadability and voltage stability index. The fast voltage stability index (FVSI) and line stability factor (LQP) for voltage stability contingency analysis are compared.
