Secondary frequency regulation, also known as Automatic Generation Control (AGC), is the process that follows primary frequency regulation. It adjusts the active power output of power plants to bring the system frequency back to its nominal value.How do energy storage systems control secondary frequency regulation?When the Energy Storage System (ESS) participates in the secondary frequency regulation, the traditional control strategy generally adopts the simplified first-order inertia model, and the power allocated to each energy storage unit follows the principle of equal distribution.
Which energy storage system is used in secondary frequency modulation control strategy research?The previous energy storage systems involved in secondary frequency modulation control strategy research mostly used the energy storage system as a small-capacity traditional frequency modulation unit for power signal distribution.
What is secondary frequency regulation?High Precision: Secondary frequency regulation allows for precise control of the system frequency, restoring it to its nominal value. - Centralized Control: Managed by the power dispatching department, enabling optimized decision-making based on the overall system conditions.
What is the difference between energy storage system and power plant?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.
How does the energy storage system respond to frequency fluctuations?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.
