Abkhazia energy storage frequency modulation power station

Do energy storage stations improve frequency stability?

With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.

What are the disadvantages of frequency modulation of thermal power unit?

The frequency modulation of thermal power unit has disadvantages such as long response time and slow climbing speed. Battery energy storage has gradually become a research hotspot in power system frequency modulation due to its quick response and flexible regulation.

How does the proposed power distribution strategy change the power distribution ratios?

The proposed strategy I changes the power distribution ratios dynamically to take full advantage of each regulatory resource. For example, when the AGC commands surge at the 64th or 102nd minute, only the ES station with better response performance outputs power to meet the FR demands as soon as possible.
