Grid Asset Manager

An asset manager controls power distribution within an aggregated distributed energy resources system (“DERs system”) having a plurality of assets. The asset manager is configured to operate with a given asset. As such, the asset manager has 1) an interface to receive asset information relating to the given asset and to communicate with another asset manager in the DERs system, and 2) a function generator configured to produce a local cost function using data relating to the given asset only. The local cost function represents a portion of a system cost function for the DERs system. The asset manager also has 3) a controller configured to use the local cost function for the given asset to manage operation of the given asset in the DERs system. In addition, the controller also is configured to determine, using the local cost function, an operating point for the given asset.

3 Independent Claims

1. An asset manager configured to control distribution of power within an aggregated distributed energy resources system (“DERs system”) having a plurality of assets, the asset manager being configured to operate with a given asset in the DERs system, the asset manager comprising: an interface configured to receive asset information relating to the given asset and to communicate with at least one other asset manager or a central controller in the DERs system; a function generator operatively coupled with the interface, the function generator configured to produce a local cost function using data relating to the given asset only, the local cost function representing a portion of a system cost function for the overall DERs system; and a controller operatively coupled with the function generator, the controller configured to determine, using the local cost function, an operating point for the given asset, the controller also being configured to use the determined operating point for the given asset to manage operation of the given asset in the DERs system.
11. A method of distributing power from an aggregated distributed energy resources system (“DERs system”) having a plurality of assets, the method comprising: using a plurality of asset managers to manage the assets, each asset including a local dedicated asset manager separate from the other asset managers or a central controller, each asset manager having an interface to receive asset information relating to its asset; for each asset, producing a local cost function using its local dedicated asset manager, each local dedicated asset manager producing its local cost function using data relating to its local asset only, the cost functions of the plurality of assets in the DERs system together representing a system cost function for the overall DERs system; determining, using the local cost function, an operating point for the given asset, using the determined operating point for the given asset to manage operation of the given asset in the DERs system.
18. A computer program product for use on a computer system for distributing power from an aggregated distributed energy resources system (“DERs system”) having a plurality of assets, the computer program product comprising a tangible, non-transient computer usable medium having computer readable program code thereon, the computer readable program code comprising: program code for communicating with a plurality of asset managers to manage the assets, each asset including a local dedicated asset manager separate from the other asset managers, each asset manager having an interface; program code for producing, for each asset, a local cost function using its local dedicated asset manager, each local dedicated asset manager producing its local cost function using data relating to its local asset only, the cost functions of the plurality of assets in the DERs system together representing a system grid cost function for the overall DERs system; program code for determining, using the local cost function, an operating point for the given asset; and program code for using the determined operating point for the given asset to manage operation of the given asset in the DERs system.
