Requirements for advanced decision support tools in future distribution network planning

This paper describes the need and requirements for advanced decision support tools in future network planning from a distribution network operator perspective. The existing tools will no longer be satisfactory for future application due to present developments in the electricity sector that increase uncertainty. Advanced decision support tools can help network planners to select among the numerous alternatives for the optimal future distribution network layout and expansion schedule. This in contrast to the existing method, whereas the generation of planning alternatives is carried out heuristically by network planners based on design directives and experience. Advanced decision support tools require the most efficient optimization techniques, must be able to find the optimal investment path considering multiple scenarios, and should not only consider classic expansion strategies but also intelligent ones (e.g. energy storage and controlling active demand). Advanced decision support tools would greatly help network operators to make better decisions under uncertainty, which contributes to an affordable, sustainable, and reliable electric energy supply.
