Can large-scale battery energy storage systems participate in system frequency regulation?

In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.

Which energy storage systems are available in Israel?

The only utility-scale energy storage system in Israel, as of 2021, is a single Pumped Hydro Storage (PHS) system, rated at 300 MW (Shikun Binui, Electra, 2016). This system helps operators to regulate the frequency during times of low demand and high solar generation, by acting as a load.

Does the Israeli power system have the resources to maintain frequency stability?

One main conclusion is that the Israeli power system already has the required resources to maintain frequency stability in case a large generation unit is lost. However, to maintain a reliable system, policy makers should encourage that the existing and additional storage will contribute to frequency regulation when there is a risk of instability.

How does integration affect the frequency stability of the Israeli power system?

The frequency stability of the Israeli power system is expected to be challenged as additional renewable energy sources are integrated. Currently in Israel, the integration of generation units and storage is not directed by policies that clearly consider how their distribution affects the frequency stability of the system.

Does battery energy storage participate in system frequency regulation?

Since the battery energy storage does not participate in the system frequency regulation directly, the task of frequency regulation of conventional thermal power units is aggravated, which weakens the ability of system frequency regulation.

Can a storage be used for frequency regulation?

If the storage is also used for frequency regulation then additional energy must be curtailed, since for the storage to provide its allocated power for frequency regulation there must be a gap between the net output power at the bus and the connection limit.
