POWER DISTRIBUTION SYSTEM

摘要

A local electricity distribution network (1) comprising a local transmission hub (13) and plurality of units (12a, 12b) arranged to selectively import and export electricity from and to the hub (13), the hub in turn being arranged to selectively import and export electricity from and to an external grid (20). The individual units (12a, 12b) decide if they are to export or import energy to or from the local transmission hub (13) based on information relating to the energy market received from the local hub. In the same way the local hub decides if it is to export or import energy to or from the external grid (20) based on energy market information received from the external grid.
