Abstract: The power infrastructure is poised for dramatic change. Drivers include rapid growth in the deployment of exponential technologies such as solar, wind, storage, EVs and power electronics; improved economic, operational and energy efficiency; and higher grid resiliency under cyber-attacks and natural disasters. Data from the field shows severe limitations with using the traditional top-down centralized control strategy, and an alternate decentralized approach with dynamic control capability is needed. The ‘future’ grid will involve a full integration of the physical and transactive grids, and will be more dynamic, with bidirectional power flows, and a real-time market that all generators and consumers will be able to participate in. This will translate into unique requirements for autonomous distributed control using power converters distributed around the grid. The presentation will highlight several key issues and possible solutions for addressing them, showing that decentralized dynamic control using power electronics is very feasible and provides a path to a future grid that is more resource-efficient, flexible, resilient and can support higher levels of PV and wind energy penetration.
