Sentence examples for tertiary frequency from inspiring English sources

A variety of frequency regulation control schemes, including inertial response, primary droop control, secondary AGC control and tertiary frequency control, are explained in detail.

In principle, grid frequency response can be divided into four regulation stages in terms of different time scales: inertial response, primary frequency response, secondary frequency response and tertiary frequency response as illustrated in Fig. 1 [11].

Nowadays, there are two types of power markets associated with tertiary frequency control, including intraday real-time market with minute-level economic dispatch and day-ahead market with daily economic unit commitment.

Compared with the other frequency controls mentioned above, tertiary frequency control has a relatively long decision time step ranging from the order of minutes to hours, which takes effect following the secondary control [10, 67].

To participate in primary, secondary and tertiary frequency control, a VSWT needs to be operated in a sub-optimal mode through the deloaded control so that a certain amount of spinning reserve margin or headroom is always available to supply additional active power in case of frequency contingency.

This control method comprises dispatching actions from the system operator, in order to achieve the power reserve deployment and restoration for the WTG's tertiary frequency control that enables unit commitment, economic dispatch and optimal power flow in accordance with market signals or other system requirements.

Secondary and tertiary plume frequency (i.e., fs and ft) cannot always be attributed to an individual river, particularly in the case of wet tropics rivers, which can merge into one heterogeneous plume.

The extent of the secondary and tertiary flood plume frequency (i.e., fs and ft), rarely could be attributed to an individual river, particularly from wet tropics rivers which can merge into one heterogeneous plume.

As a tertiary aim, we analyzed frequency domain in three log normalized frequency bands define as: high frequency power (HF; 0.15 0.40 Hz), low frequency power (LF; 0.04 0.15 Hz), very low frequency power (VLF; 0.0033 0.04 Hz), and total frequency power (PT; 0.00 0.40 Hz).

But, for a pilot study, it is acceptable to have included only migraine patients and CH frequency in tertiary centre only.

In this assay, both single YFP+ and YFP− cells give raise to primary, secondary and tertiary neurospheres with similar frequencies (Figure 4B, C).
