要約(日本語): Nowadays, the penetration of distributed generations (DGs) in the distribution system has been increased. Therefore, Microgrid (MG) has emerged as an effective way of DGs integration. MGs can be worked as a grid-connected or islanded mode. During the fault condition, Fault cuurent magnitudes will vary depending on the microgrid operating mode. Consequently, protecting the MG using the convetional method is challenging. In this paper, an adaptive dual setting method of overcurrent relays for MG is proposed. The proposed method applies setting values corresponding to MG operation modes to the overcurrent relay by referring fault voltage. Finally, the proposed method is validated using Electro-Magnetic Transients Program (EMTP).
