Implementation of Controlled Islanding Scheme for Self-healing Smart Grid

Abstract

With increase in deregulations and renewable sources of generation, the power system network is leading towards more geographical spread and interconnectedness. This causes significant challenges requiring on-line monitoring and control. It also provides a path for disturbances to propagate causing cascading failure, even blackouts. Wide area detection of potential island formation and controlled separation is considered as an effective tool against a blackout under severe disturbances. In the present work one line remaining algorithm has been utilized for implementation of controlled islanding in a section of Indian power grid.

An investigation on the application and challenges for wide area monitoring and control in smart grid

“…Whenever fault appears in the system, the wide-area security system uses the online measurement data to discover the faulty buses and, consequently, the faulted line to isolate it from the rest of the system. They play a significant role in modern power system studies; the crucial ones are discussed in the following subsections [14,15].…”
