US 2019/0379237 A1 · Smart Outlet System with Fast Frequency Tracking for Power System Frequency Control Using Distributed Appliances

Abstract

Systems and methods are disclosed to control the power grid frequency by capturing the frequency change using an extended Kalman filter method with the distributed smart outlet devices at the low-voltage distribution level; and locally control the relay that provides power to the appliance by comparing the captured frequency with the threshold sent from the cloud control center.

Claims16

Dependent claims

A method to control a power grid frequency, comprising:
