IMPROVEMENTS IN OR RELATING TO POWER TRANSMISSION NETWORKS

A network interconnection, for interconnecting a power supply network with a number of power distribution networks, including a power converter station that is connected in use adjacent to an end of a power supply network and is controllable to provide an alternating voltage source. The network interconnection also includes an interconnection bus which extends from the power converter station towards a primary point of interconnection that is connected, in use, with a primary power distribution network and at least one secondary point of interconnection which is connected, in use, with a corresponding secondary power distribution network. The network interconnection additionally includes a power regulator that is electrically connected between the interconnection bus and each secondary point of interconnection. The network interconnection further includes a power flow controller that is arranged in operative communication with the power converter station and each power regulator.
