Islanding is the intentional isolation of a part of power system during external widespread grid disturbance. This isolated part of Grid is called Island. Such a disturbance may lead to black out. Therefore, islanding scheme provides a mean to continue to supply power to the essential services in a zone or area.
In such a condition, the converter-based sources only supply to the loads called an island operation. The island operation is a standalone mode of operation of a generator (which is not connected to the electrical power grid) supplying to the loads. Fig. 1. Island Operation in Power Systems. 2. Problems with Island Operation
IEEE 1547 – Standard for Interconnecting Distributed Resources with Electric Power Systems, recommends that an island be detected and removed within two seconds of an occurrence. Power system islanding occurs when distributed generation is isolated from the grid & continues to power to the portion of the grid it remains connected to.
Utilities can also experience islanding with system faults, switching operations, environmental causes and equipment failure. For example, a fault causing a recloser to open and lockout causes the generator to become islanded from the source station. Power system islands can be intentional and unintentional.
Power system islands can be intentional and unintentional. When an island is desired in certain circumstances such as micro-grids, utilities will implement intentional islanding and necessary controls. However, unintentional islanding can be considered a risk to personal safety, power quality and equipment.
The objective of islanding are as follows: Isolate a part of power system from the Grid to make Island. Continue to supply power in Island. Avoid tripping of Generators in the Island. Quick restoration of remaining system. There are various method to detect the Grid disturbance to initiate Islanding Scheme.
