摘要： A method is provided for detecting islanding conditions in an electric power network which includes a plurality of sub-networks. The sub-networks include at least one power electrical unit and are separable from each other and a main grid supplying the network by switching devices. The method includes determining topological information of at least one sub-network of interest, detecting islanding conditions in at least one sub-network of interest on the basis of the topological information by using separate detecting devices for each sub-network of interest, and sending, on the basis of the islanding conditions detected by using the detecting devices, a disconnect signal to at least one power electrical unit in at least one sub-network of interest.

摘要： A system and method of controlling an electricity generating system that includes at least one intermittent energy source generating plant are disclosed. An exemplary method includes calculating actual operating parameters of the at least one intermittent energy source generating plant; calculating forecast operating parameters of the at least one intermittent energy source generating plant; generating intermittent energy source contingency definitions from such actual operating parameters and forecast operating parameters; analysing the intermittent energy source contingency definitions to provide contingency analyses; and controlling the electricity generating system in dependence upon such contingency analyses.

摘要： The present invention is concerned with a distribution controller (19) for controlling a distribution of electrical power in an assigned first power distribution region (1). The controller is adapted to be connected to process devices (21) which in turn interact with primary devices (5, 7, 9, 11, 13) of the assigned first region. The distribution controller is provided with a standardized, machine-readable network description of the first region and comprises means to identify, following a network reconfiguration, the extent of an orphan network section (23) that is no longer connected to the first region. The distribution controller is further adapted to transmit a description of the orphan network section to a second distribution controller (19') controlling a second or neighbouring power distribution region (1') to which the orphan section has been connected as a consequence of the network reconfiguration. Due to this capability of transmitting descriptions of the network section changing hands, there is no need to keep and update a description of the entire network in each controller of the power distribution system.
