Abstract：
 A network power oscillation suppressor based on photovoltaic batteries characterizes that it is a device for suppressing network power oscillation based on photovoltaic barriers, which converts solar energy into electric energy by a solar energy battery board and outputs DC voltage then to invert it to AC voltage to be transmitted to the network, in which, it can carry out active regulation to the network or carry out reactive regulation to the system since the inverter is composed of voltage source type quick switch off components and outputs part of active power to the network when operating normally and regulates active and reactive powers output by the oscillation suppressor based on the control rule when power oscillation happens to the network.
