Grid-connected control strategy of energy storage system based on additional frequency control. 1. Existing flat/smooth control strategy. The power of the PV station is taken as the input signal.

The electrical storage systems (ESSs) may be suited to either of the energy intensive or power-intensive applications based on their response rate and storage capacity.

The charge/discharge process of the storage device is regulated by the storage control (see Fig. 7.8 ). The input signal of the control is the error between the measured/estimated frequency, ωin, and a reference value ( ωref ). If ωin = ωref, the storage device is inactive and its stored energy is thus kept constant.
The centralized configuration aims at adjusting and controlling the power of the farms, so the energy storage system boasts of larger power and capacity. So far, in addition to pumped storage hydro technology, other larg-scale energy storage technologies that are expensive are yet to be mature.
