Distribution network planning practices based on the transition toward active distribution networks

Distribution power system networks in South Africa are transitioning from passive to active which is anticipated to result in several potential impacts concerning traditional practices employed in the planning of the distribution power system network. Through a literature review, several impacts of active distribution networks on traditionally employed passive distribution network planning practices were identified, including practices to manage and support the planning of active distribution power system networks. Risks to the economical and operational planning of the distribution power system network due to the impacts on traditional network planning practices were identified. A research study was therefore required to validate the findings from the literature. The identified impacts and practices were confirmed through a descriptive research study conducted amongst network planners in South Africa. It was determined that the transition to active distribution network planning practices amongst the sample population was to some extent. The risks associated with the employment of passive planning practices to networks transitioning to becoming active are therefore present, however opportunities to readily transition is provided.
