Load models for technical and tariff analysis of medium voltage feeders

Distribution feeders have changed with the introduction of distributed generation, and probabilistic approaches to analysis are recognized as more representative of performance than deterministic ones. Probability analysis requires probabilistic models of a wide range of loads and generation profiles. Eskom has a large data base of measurements at customers on medium voltage feeders. Some of the data have been extracted and used in this pilot project to cluster load profiles. It is possible to identify representative customer groups and representative days. The models are suitable for network performance and tariffs analysis.
