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.
As power systems become more interconnected and renewable energy sources become more prevalent, managing frequency regulation grows increasingly complex. Effective regulation supports grid stability, reduces energy losses, and ensures a dependable power supply to consumers. Maintaining proper frequency levels is vital for several reasons.
Various methods are employed to regulate frequency in power systems. Firstly, primary control adjusts generator outputs in real-time to counteract frequency deviations. Additionally, secondary control systems restore frequency to its nominal value by fine-tuning generator outputs.
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.
Frequency Regulation is a fundamental aspect of electrical engineering, ensuring that power systems operate reliably and efficiently. By maintaining stable frequency levels, engineers can protect equipment, enhance system efficiency, and provide a consistent power supply to consumers.
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.
