Abstract: A method and system to control distributed energy resources in an electric power system includes generation, storage and controllable loads. The system uses time synchronized measurements of voltage phasor and current phasors and their derivative information that may include real and reactive power to regulate and decouple both static and dynamic effects of real and reactive power flow through the local electric power system connected to the area electric power system. The method and system provides precise real and reactive power demand set point pairs; damping of real and reactive power fluctuations in the local electric power system; decoupling between real and reactive power demand response set points by means of a multivariable control system that uses time synchronized measurements of voltage and current phasors and their derivative information.

Abstract: Attributes of a power system having one or more distributed energy resources are characterized by continuously receiving data comprising a power data stream having at least two components and derived from at least one distributed energy resource. A control data stream comprising at least two components is generated. An error data stream is determined based on a difference between respective components of the power data stream to components of a reference data stream comprising at least two components. The error data stream and the reference data stream are processed to generate the control data stream. The control data stream is continuously output to enable control and/or monitoring of the power flow of at least one distributed energy resource.

Abstract: An active noise control apparatus for reducing noise from a noise source includes a microphone for detecting noise produced by the noise source, and a generalized finite impulse response (FIR) filter for receiving noise signals of the detected noise from the microphone and generating control signals for reducing the noise from the noise source. A speaker produces sound based on the control signals from the generalized FIR filter for substantially canceling the noise from the noise source.
