Evaluation and optimization of network capacity utilization for electric distribution

The optimization of network capacity utilization is becoming increasingly important in an electric distribution network (EDN) with the variation in load demand due to seasonal changes and uptake of new technologies such as photovoltaics, batteries, electric vehicles and distributed generation. The proliferation in the use of these technologies introduces uncertainties in future load demands and increases the risk of asset stranding. In this paper, the thermal model of key distribution assets are summarized. Based on the thermal model, a network evaluation and optimization system were developed and discussed. Benefits in the application of dynamic rating in an EDN to optimize and evaluate the utilization of the network assets are then highlighted.
