1. A method of analyzing the performance of a conservation system for improving the performance of an electrical power delivery system, the method comprising: receiving, by a processor of a computing device, first observation information indicative of the performance of the conservation system in a first mode, the first observation information comprising first non-linear data; receiving, by the computing device, second observation information indicative of the performance of the conservation system in a second mode, the second observation information comprising second non-linear data; sorting, by the computing device, the first observation information into a first plurality of categories that each have linear data corresponding to observations of one or more physical conditions associated with the electrical power delivery system; sorting, by the computing device, the second observation information into a second plurality of categories that each have linear data corresponding to observations of the one or more physical conditions associated with the electrical power delivery system; performing, by the computing device for each of the first plurality of categories, first separate respective regressions using the first observation information sorted into each of the first plurality of categories to generate a first model of the performance of the conservation system in the first mode, wherein the first separate respective regressions includes analyzing each of the first plurality of categories individually; performing, by the computing device for each of the second plurality of categories, second separate respective regressions using the second observation information sorted into each of the second plurality of categories to generate a second model of the performance of the conservation system in the second mode wherein the second separate respective regressions includes analyzing each of the second plurality of categories individually; determining, by the computing device, first controlled performance information indicative of the performance of the conservation system in the first mode based on the first model; and determining, by the computing device, second controlled performance information indicative of the performance of the conservation system in the second mode based on the second model.
