A novel islanding detection method for microgrids based on variable impedance insertion
نویسندگان
چکیده
Islanding is the situation in which part of the power grid, consisting of load and distributed generation (DG) is isolated from the utility grid remaining active, i.e. serving load. The idea of islanding parts of the distribution network in case of faults, in order to increase the consumer quality of service, is the basic notion behind the formation of Microgrids. In the context of Microgrids, it becomes necessary to distinguish between intended islanding e.g. due to maintenance and unintended islanding due to faults at the upstream grid. When the emergency situation ceases, the Microgrid should reconnect seamlessly

A Novel Passive Method for Islanding Detection in Microgrids
Integration of distributed generations (DGs) in power grids is expected to play an essential role in the infrastructure and market of electrical power systems. Microgrids are small energy systems, capable of balancing captive supply and requesting resources to retain stable service within a specific boundary. Microgrids can operate in grid-connected or islanding modes. Effective islanding detec...
