2MWh Energy Storage Battery

With the continuous development of new energy power sources, it has become an indispensable resource for people's life. The application range of power resources is getting wider and wider, and some problems have also appeared accordingly. In particular, the instability of power grid units begins to appear gradually. So the combined application technology of energy storage battery and power grid has received extensive attention.

At present, in order to make the energy storage battery and the power grid unit match better and achieve more precise control of the grid frequency adjustment. We can perform secondary frequency modulation on the energy storage battery. But there will be a certain information error in the process of secondary frequency modulation. In order to enhance the stability and accuracy, according to the relevant characteristics of the energy storage battery, and combined with the signal decomposition method and the IMF modal function, the relevant parameters of the secondary frequency modulation process were optimized. In this way, the grid frequency adjustment ability and power energy control ability of the energy storage battery can be further enhanced.

Compared with traditional grid units, energy storage batteries have stronger frequency regulation processing capabilities. In the face of continuous signal interference, the frequency modulation deviation is lower, and the ES battery is more stable and accurate than traditional grid units.
