The implementation of price and network based demand response programs, the pervasiveness of electric vehicles, the increasing installation of DGs, the rising customer load base of urban areas and other emerging factors are creating a distribution network loading curve which is stochastic in nature and previously unseen in shape.
This thesis unravels the real-time dependencies among active distribution network component thermal states, customer loads and distributed generation on their common environmental variables such as wind speed and solar irradiation. Through the dynamic thermal modeling of network components, the work has unlocked their real-time capacities. The introduction of real-time thermal rating in an active distribution network management system enhances the loading capacity significantly compared to static rating. This has been revealed through an increased utilization of installed DGs and through better integration potential of additional DGs.
