Abstract

An microgrid with a microgrid controller characterizes individual power generating assets of the microgrid by determining the level of expected parasitic losses in the delivery of power from the assets to loads that are being powered by the microgrid. The controller may command changes in the power delivery from a particular asset and then observe how a swing machine responds to those changes. By comparing the change in power delivery from the asset to the compensatory change in power delivered by the swing machine, the controller characterizes the expected parasitic losses in the delivery of power from the asset. The controller may generate and/or update a parasitic loss model for the asset and subsequently use that parasitic loss model to dispatch power from that asset in the future, such that the power dispatched takes into account the expected parasitic losses in the delivery of the power.

Dependent claims

A microgrid, comprising:

one or more generating asset, including a first generating asset;
a swing machine;
one or more loads;
a controller;
and
one or more computer-readable media storing computer-executable instructions that, when executed by the controller, cause the controller to:
send a first command to the first generating asset to implement a first power output change from the first generating asset;
determine a second power output change from the swing machine, wherein the second power output change is responsive to the first power output change;
compare the first power output change to the second power output change to identify parasitic losses in delivering power from the first generating asset to the one or more loads;
and
send a second command, to the first generating asset, to dispatch power from the first generating asset based at least in part on the parasitic losses in delivering power from the first generating asset to the one or more loads.

8 more elements

A method, comprising:

sending, by a controller comprising one or more processors, a first command to a first generating asset to implement a first power output change from the first generating asset;
receiving, by the controller, an indication of a second power output change from a swing machine, wherein the second power output change is responsive to the first power output change;
comparing, by the controller, the first power output change to the second power output change to identify parasitic losses in delivering power from the first generating asset to one or more loads;
and
generating, by the controller and based at least in part on the parasitic losses in delivering power from the first generating asset to the one or more loads, a parasitic loss model of the first generating asset.

2 more elements

A microgrid controller, comprising:

one or more processors;
one or more computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to:
receive, from a sensor, an indication in a first change in power delivered from a swing machine to one or more loads of a microgrid, wherein the first change in power is responsive to a second change in power from a first generating asset;
determine, based at least in part on the first change in power and the second change in power, an estimate of parasitic losses associated with delivering power from the first generating asset to one or more loads;
and
send, based at least in part on the estimate of the parasitic losses associated with delivering power from the first generating asset to the one or more loads, a command to the first generating asset to provide power the one or more loads.
