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.
With the gradual increase of energy storage equipment in the power grid, the situation of system frequency drop will become more and more serious. In this case, energy storage equipment integrated into the grid also needs to play the role of assisting conventional thermal power units to participate in the system frequency regulation.
Case study analysis of a new frequency response service designed for energy storage. Energy Storage Systems (ESS) are expected to play a significant role in regulating the frequency of future electric power systems.
Battery Energy Storage Station Frequency Regulation Strategy The large-scale energy storage power station is composed of thousands of single batteries in series and parallel, and the power distribution of each battery pack is the key to the coordinated control of the entire station.
. The value of energy storage systems (ESS) to provide fast frequency response has been more and more recognized. Although the development of energy storage technologies has made ESSs technically feasible to be integrated in larger scale with required performance
The battery energy storage system is used to compensate for the power shortage of thermal units in the first 5 seconds to achieve the purpose of regulating the frequency stability of the grid system.
Frequency regulation mechanism of energy storage system for the power grid
The results show that ESS is able to carry out frequency regulation (FR) effectively while maintaining the stored energy continuously with the proposed offset heuristics. Case studies including high PV penetration and loss of largest generating unit (LGU) also highlight the potential of ESS to take over from spinning reserves.
