Feasibility study report on frequency regulation and energy storage in thermal power plants

How does frequency regulation affect energy storage?

When the energy storage system must be charged under the condition of frequency regulation, the charge power absorbed by the energy storage system steadily decreases when the SOC is at a high boundary value, and it eventually cannot absorb the charge power when the SOC hits the critical value.

How a hybrid energy storage system can support frequency regulation?

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.

Can flexible load and energy storage be used to regulate frequency?

The method of using flexible load on the load side and energy storage on the power side to regulate frequency is proposed. The depth limit of energy storage action is proposed, which clarifies the dead zone and the maximum output limit.

What is fess in power grid?

Research in the field of frequency regulation combined with FESS in power grid is focused on the application and optimization of flywheel energy storage technology for providing frequency regulation services in power systems.

What are the challenges of frequency regulation in modern power systems?

Challenges of frequency regulation in modern power systems Frequency regulation, a method for assessing grid stability following a disturbance or fault, is evaluated by considering frequency nadir, steady-state deviation, a dynamic rolling window, and the rate of change of frequency.

Can energy storage systems reduce frequency fluctuations?

Energy storage systems have emerged as an ideal solution to mitigate frequent frequency fluctuations caused by the substantial integration of RES.
