Automatic Detection Of Distributed Energy Resources System Parameters

A method determines the topology of a DERs system having a plurality of assets, where at least one of the assets is a controllable asset. The method injects a power signal at a given frequency from a controllable asset into the DERs system. The voltage at each of the plurality of assets is measured, and the magnitude of perturbation of the voltage at the given frequency is determined for each of the plurality of assets. The method then constructs the topology of the DERs system as a function of the differences of the magnitude of perturbations of each of the plurality of assets.

3 Independent Claims

1. An asset manager configured to control distribution of power within a distributed energy resources system (“DERs system”), the 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 a) other asset manager, b) central controller, and/or c) voltage monitor in the DERs system, wherein at least one other asset is configured to inject a power signal at a given frequency into the DERs system; a voltmeter configured to measure voltage at the given frequency of the injected power signal; a topology engine operatively coupled with the interface, the topology engine configured to: determine a perturbation of voltage at the given frequency caused by the injected power signal, and c) construct the topology of the DERs system as a function of the differences of the magnitude of perturbations of each of the plurality of assets, or d) send information relating to the perturbation of voltage at the given frequency to a centralized controller where the topology of the DERs system is constructed as a function of the differences of the magnitude of perturbations of each of the plurality of assets.
8. A method of determining the topology of an aggregated distributed energy resources system (“DERs system”), the DERs system having a plurality of assets, at least one of the assets being a controllable asset, the method comprising: injecting a power signal at a given frequency from at least one of the controllable assets into the DERs system; measuring the voltage at each of the plurality of assets after injecting the power signal; determining the magnitude of perturbation of the voltage at the given frequency for each of the plurality of assets; and constructing the topology of DERs system as a function of the differences of the magnitude of perturbations of each of the plurality of assets.
15. A computer program product for use on a computer system for determining the topology of an aggregated distributed energy resources system (“DERs system”), the DERs system having a plurality of assets, at least one of the assets being a controllable asset, 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 to receive asset information relating to its asset; program code for causing the asset to inject a power signal at a given frequency into the DERs system; program code for causing the voltmeter to measure the voltage at the asset; program code for determining the magnitude of perturbation of the voltage at the given frequency for each of the plurality of assets; and program code for constructing the topology of the DERs system as a function of the differences of the magnitude of perturbations of each of the plurality of assets.
