Abstract

Aspects of a multi-level electrical distribution control system associated with an electrical distribution grid are disclosed. Coordination between the multi-level control system, the electrical distribution grid and an electrical transmission system can provide improved utilization of energy within the electrical distribution grid. Further, dynamic reconfiguration of the electric distribution grid can improve reliability of the electric distribution grid and can provide additional energy utilization pathways to reduce demand on the electrical transmission system. Moreover, improved control of the topography and energy utilization of the electrical distribution grid can improve forecasting for development of the electrical transmission system.
