Abstract

Using frequency data of the Northwest Power Grid from Feb. 15th to 28th, 2013 that is measured by PMU-light units in Shandong University, the steady state characteristics of frequency are analyzed in this paper. Duration and number of low-frequency and high-frequency events are listed. Statistics of daily highest, lowest and average frequency values are given. Ensemble averaged frequency values are calculated. Characteristics of steady-state frequency in the Northwest Power Grid are summarized and influence factors of frequency are discussed. The influence of the proportion of wind power on the frequency quality is simulated. The necessity of the application of a new frequency control method called DFR (Demand as Frequency Controlled Reserve) in the Northwest Power Grid is discussed.
