As the proportion of renewable energy infiltrating the power grid increases, suppressing its randomness and volatility, reducing its impact on the safe operation of the power grid, and improving the level of new energy consumption are increasingly important. For these purposes, energy storage stations (ESS) are receiving increasing attention.
The PCS supports the independent operation of microgrids, helps balance loads, facilitates renewable energy production, and provides electricity to remote areas. 2 Power Conversion Systems 2.1 GFL Converter Currently, most energy-storage devices in renewable- energy facilities utilize GFL converters for power input and output.
It adjusts the frequency based on changes in the output active power, eliminating the need for mutual coordination among units, Tianyu Zhang et al. Simulation and application analysis of a hybrid energy storage station in a new power system 557 resulting in simple and reliable control with a fast response.
Utilizing hybrid ESSs with the two types of energy storage converters can simultaneously harness the advantages of both systems, serve the needs of a large power grid, and may be used in future substation installations.
It was found that GFM should account for no less than 30% of the total capacity. However, this study did not provide exact numerical values. With an increase in the proportion of GFM energy storage, there is stronger support for voltage during fault occurrence and Duration of the fault.
In , the ratio of GFL to GFM energy storage was established based on the constraint of the short-circuit ratio. It was found that GFM should account for no less than 30% of the total capacity. However, this study did not provide exact numerical values.
