Working principle diagram of energy storage participating in frequency regulation

Does the energy storage system participate in frequency regulation?

It shows outstanding performance in frequency regulation comparing with the traditional frequency regulation resource. This paper reports a review of the energy storage system participating in frequency regulation, including frequency regulation market and energy storage technology.

Why is frequency regulation important in energy systems?

Due to the very high penetration of energy systems, there is a need for frequency regulation, hence different control strategies are employed to overcome this problem.

How can a wind energy system control the frequency?

The frequency regulation can also be achieved in the wind energy system by using the battery storage [ 5] and the battery energy storage can be optimized for controlling the frequency [ 6 ]. The statcom integration with energy storage can give better results [ 7] and this can be achieved in the power system [ 8, 9 ].

How to compensate for mismatch of generation-load in energy storage system?

To compensate for the mismatch of generation-load, an advanced energy storage system is proposed in the paper so that the nominal frequency of the power system is maintained. The fast ramping merit of the energy storage system is a feat to give regulation of the frequency.

What are energy storage systems used for?

The energy storage systems are used for controlling the frequency of the system [ 25 ]. To compensate for the mismatch of generation-load, an advanced energy storage system is proposed in the paper so that the nominal frequency of the power system is maintained.

How important is ESS in controlling frequency fluctuation in a power system?

The importance of ESS in controlling the frequency fluctuation in a power system has been also described. The proposed ESS model can further be improved by considering the efficiency of the converter system and choosing the realistic values of the electrical components.
