Frequency regulation using both thermal power and energy storage systems shortens thermal unit response time, enhances the unit's grid performance, improves regulation speed and precision, and significantly boosts comprehensive performance indicators.
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.
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.

Therefore, de-loading of renewable energy generations to provide frequency reg- ulation is not technically and economically viable. As such, energy storage systems, which support are the most suitable candidate to address these problems.
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.
The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
The fuzzy theory approach was used to study the frequency regulation strategy of battery energy storage in the literature, and an economic efficiency model for frequency regulation of battery energy storage was also established. Literature proposes a method for fast frequency regulation of battery based on the amplitude phase-locked loop.

It is located at Poolbeg Energy Hub, where ESB – around 95% owned by the Irish state with the remaining stake held by its employees – is planning to deploy a combination of clean energy technologies, including offshore wind, hydrogen, and battery storage, over the coming decade. We currently have more than 300MWs of battery storage capacity in operation in Ireland, making it one of the largest battery portfolios in Europe. We plan to develop a pipeline of large scale battery projects, as well as additional renewable enabling technologies. Eamon Ryan (centre) cuts the ribbon to inaugurate the 75MW/150MWh Poolbeg BESS, flanked by ESB's Jim Dollard (left) and Fluence's. The project, operational since late November 2023, has a capability of providing 75MW (150MWh) of ffast-acting energy storage to help provide grid stability and deliver more renewables on Ireland's electricity system. Energy Storage Ireland is a representative association of public and private. Ireland's ESB has opened a battery energy storage system at its Poolberg site in Dublin.

Depth of Discharge refers to the percentage of a battery's total capacity that can be used before recharging. It is essentially the inverse of another important energy storage metric, State of Charge (SoC), which measures how much energy remains in the battery.

Battery Energy Storage Systems (BESS) can mitigate voltage regulation issues, as they can act quickly in response to the uncertainties introduced due to solar PV. However, if there is no coordination between existing devices such as On Load Tap Changing Transformers (OLTC) and BESS, then BESS takes all the burden and is generally over-utilized.
In this way, the regulation of DC bus voltage of the PV/BES system can be enhanced as compared to the conventional regulation that is solely based on the voltage-sourced converter (VSC). For the grid side VSC (G-VSC), two control methods, namely, the voltage-mode and current-mode controls, are applied.
