1. A computer-implemented method comprising:
at a centralized controller, performing:
executing algorithms to generate centralized predictions of a unit commitment for a first period of time, wherein the unit commitment is a charging and discharging schedule of energy storage systems to one or more electrical vehicle charging stations of a plurality of electrical vehicle charging stations;
wherein the centralized predictions relate to energy usage across the plurality of electric vehicle charging stations;
generating one or more centralized baseline signals based on the centralized predictions, wherein the one or more centralized baseline signals are distributed to the plurality of electrical vehicle charging stations to control unit commitments for all of the electrical vehicle charging stations in the plurality of electric vehicle charging stations based on the centralized predictions for the first period of time;
at each decentralized controller of a plurality of decentralized controllers, each decentralized controller being associated with a corresponding subset of electric vehicle charging stations in the plurality of electric vehicle charging stations, performing:
receiving the one or more centralized baseline signals;
monitoring interactions at the corresponding subset of electric vehicle charging stations during the first period of time; and
updating the one or more centralized baseline signals in real-time based on the interactions to produce one or more locally-updated baseline signals which comprise modifications of the one or more centralized baseline signals;
communicating the one or more locally-updated baseline signals to the corresponding subset of electric vehicle charging stations; and
controlling energy flow from the one or more energy storage systems to the subset of electric vehicle charging stations based on the one or more locally-updated baseline signals.
