Dispatching vehicle-to-grid ancillary services with discrete switching

摘要

Techniques for controlling dispatch of electric vehicles (EVs) to perform vehicle-to-grid regulation of power of an electric grid are presented. An aggregator component can individually control transitioning respective EVs of a set of EVs between a charging state and a not-charging state. The aggregator component includes a dispatch controller component (DCC) that can employ a defined dispatch algorithm for EVs to facilitate enabling the DCC to perform unidirectional regulation. The DCC can switch EV charging stations on and off using remote switches to meet a system regulation signal. The DCC can use the dispatch algorithm to make determinations regarding which EV to switch using charging priorities, in accordance defined power regulation criterion(s). The aggregator component can reduce communication signals used to adjust dispatch by sending switching signals to only those EVs of the set of EVs that are changing their charging state at a given time.

1. A system, comprising:
a processor, coupled to a memory, that executes or facilitates execution of executable components, comprising:
an aggregator component that aggregates and manages charging of a set of electric vehicles (EVs) associated with an electric grid; anda dispatch controller component that controls switching of at least a subset of EVs of the set of EVs between an on state and an off state at a given time, based at least in part on respective priority levels of respective EVs in the set of EVs, wherein, for the respective EVs of the set of EVs, the dispatch controller component determines a dispatch error between a dispatch of the EV at a defined point in a scheduling period and a target dispatch of the EV.
