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.
quency regulation services. However, modern power systems with high penetration levels of generation. 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.
By actively involving of energy storage, the strategy also helps to decrease the system's frequency regulation deviation. This results in a reduction of 2699.458 MW in frequency regulation loss and a decrease of 41.18 % in frequency regulation deviation. As a result, the overall frequency regulation performance of the system is improved.
The hybrid energy storage system combined with coal fired thermal power plant in order to support frequency regulation project integrates the advantages of “fast charging and discharging” of flywheel battery and “robustness” of lithium battery, which not only expands the total system capacity, but also improves the battery durability.
In order to enhance the frequency regulation capacity of thermal power units and reduce the associated costs, multi-constrained optimal control of energy storage combined thermal power participating in frequency regulation based on life loss model of energy storage has been proposed. The conclusions are as follows:
In literature [20, 21], the characteristics of energy storage frequency regulation theory are utilized to effectively improve the system's frequency restoration. In establishes a frequency regulation cost accounting model that considers the impacts of energy storage life.
