Title:
SYSTEMS AND METHODS FOR DYNAMIC POWER COMPENSATION, SUCH AS DYNAMIC POWER COMPENSATION USING SYNCHROPHASORS
Document Type and Number:
WIPO Patent Application WO/2011/159786
Kind Code:
A4
Abstract:
An electrical power generation system, such as a solar power inverter, can provide dynamic real-time power compensation, so as to mitigate the effects of voltage sags and swells (e.g., on a utility grid) and thereby provide voltage support functionality to a local grid. The electrical power generation system can do so by receiving first synchrophasor measurements that are taken at a point on the utility grid and transmitted to the electrical power generation system and by taking second synchrophasor measurements. The first and second synchrophasors indicate voltage magnitude and frequency of the alternating current (AC) at their respective measurement points. The electrical power generation system can compare the first synchrophasors with the second synchrophasors and based upon the comparison, vary the power factor of the power the electrical power generation system generates (e.g., by either supplying or absorbing reactive power).
