US 2026/0100850 A1 · REAL TIME LOAD AND ENERGY MANAGEMENT OF DISTRIBUTED ENERGY RESOURCES

Abstract

Techniques for allocating a load capacity to on-site smart sensors coupled to distributed energy resources (DERs) are described herein. For example, a management application may include load limiting logic configured to monitor total load at a site periodically (e.g., at 1 second intervals). In some examples, when an EV charging session is initiated by a customer, the management application may determine a total site load relative to a maximum EV charging load. In response to the total site load exceeding a threshold, such as a rated capacity of the service panel, the management application may throttle the EV charging load such that total site load stays below the threshold (e.g., within rated capacity). In some cases, in response to the total premise load declining below the threshold, the management application may increase the EV charging limit.

Dependent claims

A method comprising:

connecting to a WI-FI network gateway at a location;
receiving, via an application stored on a smart utility meter and the WI-FI network gateway, a multicast domain name system (mDNS) query from an electric vehicle supply equipment (EVSE) located at the location;
sending a confirmation message to the EVSE indicating service information associated with the smart utility meter;
establishing a secure connection with the EVSE based at least in part on the service information;
and
providing a utility resource to the EVSE based at least in part on establishing the secure connection.

A method comprising:

receiving, via an application and from a utility service provider, a maximum load constraint associated with a location;
determining a current total load usage at the location;
and
determining if the current load usage is below the maximum load constraint, wherein:
in response to the current load usage being above the maximum load constraint, reducing a charging load of an EVSE such that current total load stays within the maximum load constraint associated with the location;
or
in response to the current load usage being at or below the maximum load constraint, increasing the charging load of the EVSE.
