Controlling distribution of electrical power

A method of controlling distribution of electrical power over a power distribution system comprising first and second distribution regions and first and second distribution controllers connected to process devices which in turn interact with primary devices in a corresponding one of the distribution regions, respectively, the first distribution controller being configured to communicate with the second distribution controller assigned to the second power distribution region assigned to the second power distribution region distinct from the first power distribution region, the method comprising:

• processing, by a processing means of the first distribution controller, data received from process devices connected to the first distribution controller, the process devices connected to the first distribution controller being configured to interact with a primary device of the first power distribution region based on the received data;
• deriving, by the processing means of the first distribution controller, actions related to the primary device of the first power distribution region based on the received data;
• and
• coordinating, by a coordinating means of the first distribution controller, the actions in the event of conflicting derived actions, the coordinating comprising at least one of:
• coordinate conflicting actions related to the primary device and proposed by the processing means of the first distribution controller, based on a decision supporting input from the second distribution controller, and
• coordinate conflicting actions related to the primary device and proposed by at least one of the processing means of the first controller and a processing means of the second distribution controller.
