Test Specification TC14.TS2
Test Specification Definition
ID | TC14.TS2 |
---|---|
Reference to Test Case | TC14 |
Title of Test | Synthetic inertia and fast frequency response/control provided by converter-based resources: power system stability assessment. |
Test Rationale | The test aims to verify that power converters limit the ROCOF and the frequency deviation considering also the variability attributes (Frequency variation, voltage set-point, voltage and current harmonics, measures accuracy, interaction between each power converter providing FFR and SI and other components, grid parameter, communication and controller delay). |
Specific Test System (graphical) | IEEE 9 bus |
Target measures | Power and frequency measures time series of each power converter. |
Input and output parameters | Production and consumption profiles, FCR, FFR and SI control mode ON/OFF, power baseline, number of power converters, mechanical inertia. |
Test Design | The test design is the same of the TC14.TS1 but consumption and non-controllable production will be change instead of frequency. |
Initial system state | Frequency: 50 Hz Power baseline: at least three different initial states; one with lower power exchange, one with medium power exchange and one with high power exchange. |
Evolution of system state and test signals | Consumption or production change in order to have the same frequency variation of the TC14.TS1. |
Other parameters | See variability attributes. |
Temporal resolution | At least 0.1 ms. |
Source of uncertainty | Measures accuracy in case of non-simulation experiments. |
Suspension criteria / Stopping criteria | Disconnection of one or more components and/or frequency instability. |
