Description
– This mode applies to scheduling scenarios in
ground-mounted plants.
– In scheduled discharge, the AC output aims
to reach the target value of the scheduled
active power: PV power supply is prioritized.
If the PV power is sufficient, the system
outputs at the target value and the excess PV
power is used to charge the batteries. If the
PV power is insufficient, the batteries
supplies power.
– In scheduled charge, the AC output aims to
reach the target value of the scheduled
active power: If the battery charging power is
insufficient or the PCS power is limited, the
grid supplies power. If the batteries have
excess power, PV power is used to charge the
batteries.
