Clustering Technique for Enhanced Optimization and Control of Distribution Networks

Significant changes in the structure and nature of consumption in distribution networks are causing significant challenges for distribution network operators. To maintain a high level of reliability and security of supply, the operation of a low-voltage network in the near future has to be supported by sophisticated optimization and control algorithms. However, the low voltage network is a challenging environment, involving a large number of different network participants. The large number of controlled entities makes the optimization and control of this type of network a difficult task. To decrease the complexity of the problem, a clustering technique is presented. The proposed clustering technique allows aggregation of individual network participants into several groups (clusters), that can be controlled as a single entity while respecting the impacts of individual network participants on the network operation. The presented clustering technique is demonstrated on a sample network based on a real low-voltage feeder.
