Abstract

Ongoing distribution grid modernization efforts are introducing an increasing number of advanced applications granted control of field devices. An emerging challenge is the Deconfliction Problem of coordinating conflicting control commands issued by multiple applications to the same device. As an alternative to custom, centralized grid orchestration techniques, the concept of distributed deconfliction is introduced. Conflicts between centralized and distributed applications are decomposed based on definition of local distributed control areas based on the network topology. This work introduces a distributed deconfliction architecture derived from the principles of Grid Architecture and the IEC 61968-1 Interface Reference Model. Setpoint-informed optimization and objective-informed multi-criteria decision-making are compared as two possible numerical techniques for selection of final device setpoints
