Appl. No.:

16/226481

Inventors:

- Richland WA, US
Abhishek Somani - Richland WA, US
Ronald B. Melton - Richland WA, US

Assignee:

Battelle Memorial Institute - Richland WA

International Classification:

H02J 3/18
H02J 13/00
H02J 3/38
G05B 19/042
G06Q 50/06

Abstract:

Apparatus and methods are disclosed for performing voltage management in a power grid by engaging distributed energy resources (DERs) to source or sink reactive power. An administrator can produce a demand curve relating demanded quantities of reactive power for an upcoming interval to corresponding marginal prices the utility will pay for the quantities. Controllers of one or more DERs electrically coupled to the power grid can produce a supply curve relating offered quantities of reactive power for the upcoming interval to marginal prices the DER will accept to supply the quantities. A coordinator controller can determine a clearing price and quantity for reactive power for the upcoming interval based on the demand and supply curves and cause the one or more DERs to collectively dispatch the clearing quantity of reactive power to the power grid during the upcoming interval.

H02J 13/00
H02J 3/18
G05B 15/02

Abstract:

Apparatus and methods are disclosed for restoring operation of a power grid comprising a plurality of reclosers and distributed energy resources (DERs) responsive to abnormal conditions by determining and implementing a reconfiguration for the power grid. The reconfiguration can specify respective new statuses for one or more of the reclosers and/or respective quantities of reactive power to be supplied by one or more of the DERs. The reconfiguration can be determined based on a plurality of constraints using an objective function, the constraints being determined based at least in part on recloser status data and/or DER power generation capability data. Respective cleared quantities of reactive power for the DERs to supply to the reconfigured power grid can be determined via a transactive control scheme, and the reconfiguration can be updated prior to implementation based on the results of the transactive control scheme.

H02J 3/06

Abstract:

Disclosed herein are representative embodiments of methods, apparatus, and systems for facilitating operation and control of a resource distribution system (such as a power grid). Among the disclosed embodiments is a distributed hierarchical control architecture (DHCA) that enables smart grid assets to effectively contribute to grid operations in a controllable manner, while helping to ensure system stability and equitably rewarding their contribution. Embodiments of the disclosed architecture can help unify the dispatch of these resources to provide both market-based and balancing services.
