1. A method for analyzing power quality events in an electrical system, comprising:
processing electrical measurement data from or derived from energy-related signals captured by a plurality of metering devices to generate or update a plurality of dynamic tolerance curves, wherein each of the plurality of dynamic tolerance curves characterizes a response characteristic of the electrical system at a respective metering point of a plurality of metering points in the electrical system;
selectively aggregating power quality data from the plurality of dynamic tolerance curves;
analyzing power quality events in the electrical system based on the selectively aggregated power quality data; and
adjusting or controlling one or more parameters, processes, conditions or loads associated with the electrical system in response to the power quality events analyzed.
