The accelerating deployment of distributed resources is posing scalability challenges for the control and operations of modern electric power systems. Large numbers of smaller devices that are owned and operated by an array of stakeholder pose challenges for traditional centrally controlled systems. Microgrids have been shown to be one option for aggregating distributed resources into a single control point, but mixed ownership of microgrids poses further challenges because of potentially different operational goals. Consensus algorithms provide a potential method for mixed ownership microgrid controllers to distributedly achieve global operating goals.
