Maximization of Distributed Generation with consideration of Fuse-Recloser coordination

Distributed Generation (DG) is more and more widely used in power system. However, the installation of DG increases the short circuit level and may affect the Fuse-Recloser coordination. As a result, it can bring about the reduction of system reliability. The impact depends on sizes, locations, and control modes of DG. Therefore, this paper presents a procedure to determine the maximum capacity of DG in order to maintain the Fuse-Recloser coordination. In addition, the comparison of system reliability with and without using the proposed maximum capacity of DG is presented via three reliability indices, i.e. SAIFI, SAIDI, and ENS. The performance of the proposed method is tested in the reliability test system RBTS bus 2.
