The Orkney Active Network Management (ANM) Scheme has been operational on the Orkney islands since 2009. In 2012 the project was sufficiently demonstrated to allow the process of handing it over to the Business to commence. This roll out across other relevant areas would allow SSEPD to get maximum value for their customers through using the ANM concept. As part of the handover the system was analysed to make sure that it fitted within company process and policy. As part of this review it was decided to automate some of the functionalities of ANM when responding to 33kV network configuration changes, which as a current practice is currently completed manually. Whilst completing this work it was discovered, due to the proliferation of the micro generators, that more than just the ANM controlled generators were required to reduce their export during certain network outage conditions. As such the decision was taken to incorporate the intertrip scheme that controls the tranch of generators installed prior to the deployment of ANM. This incorporation will allow the network to stay within its operational limits, whilst at the same time ensuring that a maximum amount of generation can be allowed onto the network in a co-ordinated manner.
