Incorporating the smart grid concept in network planning practices

Ongoing developments in the electricity system are changing the requirements for planning and design of distribution networks. Based on field research at several Dutch distribution network operators a conceptual planning process is defined and current practices in distribution network planning in the Netherlands are investigated. Currently mainly traditional deterministic approaches are applied, but the increased focus on efficiency and optimal utilisation of existing grids leads to the exploration of more detailed methods. So far, the uncertainties in costs and benefits and the absence of clear legislation hinder the incorporation of smart grid technologies in routine network planning.
