Energy storage systems, particularly Battery Energy Storage Systems (BESS), play a crucial role in improving frequency regulation by providing quick and precise responses
When the system frequency fluctuates, power plants first perform primary and secondary frequency regulation, while the energy storage system assists by providing additional power support when the power plants' capacity is insufficient to stabilize the frequency.
Traditionally, centralized power plants (like hydropower, steam generators, or combustion turbines) have provided frequency regulation services. Following recent technological and cost improvements, energy storage technologies (including batteries and flywheels) have begun to provide frequency regulation to grid systems as well.
When the system frequency fluctuates, the energy storage system automatically adjusts its power output in response to frequency changes, thereby assisting in frequency regulation. In this mode, the energy storage system can respond quickly to frequency fluctuations, enhancing system frequency stability.
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.
At the same time, with the rapid development of renewable energy and the increasing demand for flexibility in power systems, electrochemical energy storage technology has shown great potential in frequency regulation due to its unique advantages.
Frequency regulation in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
