Development of Active Network Management (ANM) scheme for Orkney.

The amount of Distributed Generation (DG) allowed to connect to the Orkney distribution network is limited by network constraints. A significant increase in renewable energy is an important part of the plan to meet UK and international emissions reductions targets. Renewable resources are often located in remote areas where the connection to the national grid will be via weak distribution networks requiring substantial network infrastructure reinforcement.

Theoretically, networks may be filled to capacity with contracted renewable generation but, due to diversity, the actual real time contribution can be significantly less than the contracted capacity. If renewable resources are to have their full potential realised then a combination of new network technologies and advances in system planning and operation are required.

The Orkney Isles are an area of abundant renewable resource with several wind farms and the European Marine Energy Centre. Orkney is connected to the mainland network by two 33kV submarines cables and analysis showed that an active network management scheme may be capable of releasing capacity for DG connections by up to three times the firm capacity of the existing distribution network.
