Comparing the Linear and Square Models for Defining the Power System Frequency Static Response Slope based on Transient Synchrophasor Data

The possibility assumed in previous research of utilizing the linear model for defining the power system frequency static response slope based on synchrophasor data of transients accompanied by frequency changes is investigated in detail. Square model usage is considered. The comparison is done using 13 recordings of events that caused frequency deviations in Northern part of Tyumen region including four considered in the previous publication.
