Fig. 15 shows graphs of the frequency and the power response of the energy storage system during a frequency event trigger. A 500 MW imbalance was created within the system, resulting in a substantial drop in frequency. The change in frequency was observed by the ESS in the laboratory, which dispatched power according to the EFR response curve.
Simulation study and experimental test are carried out to validate the effectiveness of frequency response provided by the multilevel energy storage.
The multilevel energy storage solution can effectively regulate RAPS system frequency while avoiding abrupt and frequent charging/discharging of the LABs and significant mechanical/electromagnetic stress on the WECS.
Frequency is a crucial parameter in an AC electric power system. Deviations from the nominal frequency are a consequence of imbalances between supply and demand; an excess of generation yields an increase in frequency, while an excess of demand results in a decrease in frequency .
The deadband around 50 Hz allows an ESS to manage its SoC using a proportion of its tendered power . National Grid has agreed contracts for 201 MW of EFR capacity, which will include the construction of a 49 MW ESS. However, there is lack of appropriate studies to support the design, validation and optimization of such implementations.
Increased penetration of renewable generation, and reduction in the inertia provided by large synchronous generators, are likely to increase the severity and regularity of frequency events in synchronous AC power systems.
