Does VSG control affect the frequency stability of energy storage devices?
It is stated in Deng et al. (2018) that the use of VSG control allows the energy storage device to participate in the primary frequency regulation process of the system, but when the frequency deviation is very large, the sag control leads to a decrease in the frequency stability of the system.
Can adaptive VSG control improve the performance of energy storage systems?
The results show that the adaptive VSG control method proposed in this paper can actively adjust the magnitude of the virtual inertia in real time based on the frequency changes, thus improving the stable operation performance of the system and increasing the service life of the converters, energy storage units, and other equipment.
Does VSG technology improve the response efficiency of energy storage systems?
The unbalanced power also decreased from 0.466 kWh to 0.342 kWh. This indicates that the adaptive characteristics of VSG technology not only improve the response efficiency of energy storage systems to frequency changes, but also optimize the management of the state of charge.
What is VSG technology?
By utilizing advanced algorithms, real-time monitoring data can be transformed into accurate power grid models. VSG technology allows control systems to deeply understand the dynamic characteristics of power systems, and thus reproduce the true dynamic behavior of the power grid (Mcglone et al. 2023). Figure 1 displays the control structure.
What is the energy storage system model?
The model includes new energy generation, energy storage system, and VSG control module to simulate load fluctuations and their impact on frequency response. The initial state of charge of the energy storage system is set to 50%, taking into account the frequency changes and response characteristics under different operating conditions.
Is there an adaptive control strategy for virtual synchronized generator (VSG)?
