Abstract
Based on voltage/frequency passive anti-island protection
the configuration principle and scheme of anti-island protection are analyzed in detail. The range of device setting is given
which avoids the conflict between anti-islanding and low voltage ride-through or grid adaptability requirements of storage power station. Finally
the coordination strategy with inverter anti-island protection is discussed to eliminate the problem of protection blind zone in the anti-island protection device
ensure safe and reliable operation of the grid-side energy storage power station
and provide effective guarantee for power system peak shaving and fault recovery.
