FRAT- Frequency Response Tool

Focus Topic

Frequency response tool automates the power system frequency response analysis process

Primary Purpose

Perform the estimation of the frequency response characteristics based on the phasor measurement unit (PMU) measurements, collect and process statistical information on the frequency response characteristics

Description

The FRAT is a standalone Windows application with a user friendly GUI with advanced visualization (Figure 6-1) (Quint et al. 2016). The FRAT manages the database of under frequency events and calculates the Frequency Response Measure (FRM) at an interconnection- and BA-level, as defined by the North American Electric Reliability Corporation (NERC) BAL-003-1 standard (NERC 2015).
The application can use both PMU data, where available, and Supervisory Control and Data Acquisition (SCADA) data.
In addition to NERC FRM, the application calculates the nadir-based frequency response (FR) using Point C. FR metrics are saved in an application database. The primary users of the FRAT are balancing authorities and reliability coordinators.

The application allows the user to compare measurement based FR vs. model-based FR response.
The main features of FRAT include (Etingov, Kosterev, and Dai 2014, Quint et al. 2016):
• Automated determination of frequency response parameters (initial frequency, frequency nadir, settling frequency, etc.).
• Visual inspection and adjustment of automatically determined FR parameters.
• Calculation of FRM and nadir-based FRM, as well as additional performance metrics such as FRM at 30 sec, 60 sec, 90 sec, etc.
• Frequency response monitoring for: (1) interconnection-wide, (2) Balancing Authority (BA), and (3) power plant-level
• Archiving historical events into an internal database and baselining system performance.
• Performing statistical analysis and FR event data (linear regression, basic descriptive statistics).
• Visualizing FR performance using different plots based on date, time, day of the week, wind/solar generation, etc.
• Automatically generate reports (including FRS 1 form) in Word format
