Equatorial Guinea solar power station energy storage frequency regulation

How does solar photovoltaic integration affect system frequency stability?

Meanwhile, the rise of solar photovoltaic integration into distribution networks has significantly emphasized the challenge of maintaining system frequency stability due to the inadequate reserve power from conventional sources . A reduction in the system inertia exacerbates the rate of change of frequency (RoCoF) during sudden disturbances.

Is there a multi-type energy storage configuration method for primary frequency regulation?

Therefore, a multi-type energy storage (ES) configuration method considering State of Charge (SOC) partitioning and frequency regulation performance matching is proposed for primary frequency regulation. Firstly, the Automatic Generation Control (AGC) signal is decomposed and reconstructed using the variational mode decomposition (VMD) method.

Can photovoltaic power stations be controlled by a joint frequency modulation optimization?

The result of this project can also be extended and applied to the primary frequency control of grid-connected photovoltaic power stations in the power grid, and even further applied to the joint frequency modulation optimization control of the multi-energy complementary interconnected power system of the power grid.

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.
