Definition of DG protection planning methods for network information systems

The amount of distributed generation (DG) located in distribution networks increases rapidly. This may have certain impacts on the traditional protection methods. To ensure safe and selective operation, these impacts should be taken in to account and included when planning DG interconnection. The distribution network operators (DNOs) are increasingly facing the challenges related to DG. At the same, needs for developing the planning systems for DG interconnection purposes have been observed. This paper describes the network protection impacts of DG and the typical tools applied for network planning. The definition of protection planning functionality will be stated. Requirements and development needs for the information system in which the methods are to be implemented are also discussed. Finally, the future work to be performed under project ADINE co-funded by European Commission will be outlined.
