SYSTEMS AND METHODS FOR MANAGING POWER QUALITY EVENTS IN AN ELECTRICAL SYSTEM

The invention relates to a method for managing power quality events in an electrical system, comprising:- processing electrical measurement data from or derived from energy-related signals captured by at least one intelligent electronic device (IED) to identify at least one power quality event associated with one or more loads monitored by the at least one IED, wherein the at least one IED and the loads are installed at respective locations in the electrical system;- determining at least one means for mitigating or eliminating an impact of the at least one identified power quality event on the electrical system based, at least in part, on an evaluation of a dynamic tolerance curve associated with one or more loads in the electrical system and characteristics of mitigating techniques and apparatuses, wherein the dynamic tolerance curve associated with the one or more loads characterizes response of the one or more loads to the at least one identified power quality event, and the impact of the at least one identified power quality event on the electrical system; and- indicating a best means for mitigating or eliminating the impact from the at least one means for mitigating the impact.
