Dispatching vehicle-to-grid ancillary services with discrete switching

A method, comprising:

• with respect to a set of electric vehicles (EVs) associated with an electric grid, generating, by a system comprising a processor, a first group comprising a first subset of EVs and a second group comprising a second subset of EVs of the set of EVs, based at least in part on respective priority levels of respective EVs of the set of EVs, wherein the first subset of EVs are associated with a first subset of priority levels and the second subset of EVs are associated with a second subset of priority levels;
• controlling, by the system, switching of at least a portion of the respective EVs between a charging state and a not-charging state at a given time, based at least in part on the respective priority levels of the respective EVs;
• and
• recalculating, by the system, the respective priority levels of the respective EVs based on an occurrence of a condition of a set of conditions relating to at least one of EV dispatches, an amount of time since a calculation or a recalculation of the respective priority levels, or feedback information associated with the respective EVs.

A non-transitory computer-readable storage medium storing executable instructions that, in response to execution, cause a system including at least one processor to perform operations, comprising:

• to facilitate charging of respective electric vehicles (EVs) of a set of EVs associated with an electric grid, generating a first group comprising a first subset of EVs and a second group comprising a second subset of EVs of the set of EVs, based at least in part on respective priority levels of the respective EVs, wherein the first subset of EVs are associated with a first subset of priority levels and the second subset of EVs are associated with a second subset of priority levels that are lower priority levels than the first subset of priority levels;
• controlling transitioning of a portion of the respective EVs between a charging state and a not-charging state at a given time, based at least in part on the respective priority levels of the respective EVs;
• and
• redetermining the respective priority levels of the respective EVs in response to an occurrence of a condition of a set of conditions relating to at least one of EV dispatches, a time since a determination or a redetermination of the respective priority levels, or feedback information associated with the respective EVs.
