Island Display

The Island Display presents information on the system’s islands. Users of the software do not directly create and maintain islands, but instead islands are automatically created by PowerWorld Simulator as the users changes the system. For more information about how the islands are created see the help topic on Island Creation.

An island consists of a group of buses that are electrically connected via ac transmission lines and transformers and thus operate in synchronism with one another. Multiple islands can be connected together via dc transmission lines. Each island requires a slack bus. All systems have at least one island, which may encompass the entire system.

The Island Display is a class of Case Information Display and therefore can be used in a manner consistent with all other case information displays. It has a local menu from which you can print, copy, and modify its information. You can also sort the islands information by clicking on the heading of the field by which you want to sort.

To show this display select Aggregations > Islands in the Model Explorer. The display is only available in run mode.

You cannot modify any fields on this display.

 

The display has the following fields for each island:

Slack Bus Number, Slack Bus Name, Slack Bus Area

Number, name and area of the slack bus for the island. Each island requires at least one slack bus.

Total Buses

Total number of buses in the island.

Energized

Indicates whether the island is connected to a source of power.

Gen MW, Gen Mvar

Total real and reactive generation for the island.

Load MW, Load Mvar

Total real and reactive load for the island.

Scheduled Exports

The power scheduled to be provided by the island to other regions of the system. Because the island is isolated from the rest of the system, this export requirement is currently not met.

DC MW Exports

The power provided by the island to other regions of the system across a DC line.
