The proliferation of distributed photovoltaic (PV) systems is creating operational challenges for the distribution grid, such as reverse power flows and voltage stability. These issues are exposing the weaknesses of existing grid controls and call for new control paradigms that can enable a massive integration of solar energy to operate with reliability and efficiency guarantees. To this end, next generation distribution system planning and operation tools are required to be dynamic, automated, data driven, highly scalable, cost effective and enable effective decision making at timescales that match the dynamics of intermittent generation. This panel will present an evaluation of a hybrid control approach where a centralized control layer (e.g. advanced distribution management systems) will be synergistically complemented by distributed control algorithms for PV inverters and autonomous control of grid edge devices that interact with the centralized control layer. Panelists will present the different approaches of the architecture.
