Improving TSO-DSO Coordination Through Dynamic Operating Envelopes Allocation​

This presentation discusses solutions for secure operation of complex power systems.
We focus on the decoupling of the operation of the different parts of the network, from transmission to distribution networks. In the proposed solution, to decouple the network, each operator agrees with the other operators to comply with power and voltage constraints at their network interfaces. By respecting these constraints, each operator, including both transmission operators and distribution operators, may act independently of other actors. The network operation is decoupled. We explain how these power and voltage constraints, called dynamic operating envelopes (DOEs) and contractual operating envelopes (COEs), can be optimally fixed. An illustration is provided and highlights how this procedure maintains grid security while offering operational independence.
