Frequency regulation refers to the active power regulation behavior in the power system to maintain the stability of the grid frequency (usually 50 Hz or 60 Hz). Since power generation and consumption must be balanced at all times, when the system load changes and causes the frequency to deviate, it is necessary to quickly respond by adjusting the output power of power generation or energy storage to restore the frequency to the normal range.
Principle Overview:
The grid frequency reflects the active power balance state of the system.
Frequency decrease → Load > Generation → It is necessary to increase power supply
Frequency increase → Generation > Load → It is necessary to reduce power supply
