Operation mode

ESS installed at the new energy power generation side can be operated under the following several modes, each independent from each other and not necessarily multifunctional:

1.    Power variation rate limitation. Power variation rate is limited to a certain range relying on real-time measurement of the output power of a wind power plant. The ESS starts charging when the output power of the wind power plant climbs sharply; it discharges when the output power drops sharply. This aims at meeting the needs of the grid for a certain power variation rate. Under such a mode, the ESS should be installed close to the wind power plant.

2.   Grid power variation support. The ESS charges and discharges power according to the grid's dispatch instructions to make extra adjustment for the grid. Under such a mode, the ESS does not target a certain wind power plant. Therefore, it is not necessary for the ESS to be installed near the wind power plant.

3.    Voltage regulation. The ESS works on reactive power absorption or release according to real-time need for regulation of transmission voltage.

4.    Frequency regulation. The ESS can charge or discharge power according to the signal received each second. Under such a mode, the ESS can maintain a long-term operation at a set State of Charge value.

5.   Low-voltage ride-through. The ESS works in power electronic equipment for low-voltage ride-through. Most wind power plants have power electronic equipment. So there is no need for extra support.
