Why active power control?
In some countries, or through the local energy supply company (EVU), it may be stipulated that not the full output (e.g. only 60%) of the PV system may be fed into the public grid.
In this case, some energy suppliers offer PV system owners the option of having their system regulated by the energy supplier via variable active power control, thereby increasing the generation output back to up to 100%.
Ask your energy supplier which application rule applies to you.
The planner of a PV system can usually choose between several types of active power control:
- Limiting the feed-in power to a defined percentage of the PV power at the grid connection point
Limitation of the PV feed-in capacity - Limiting the feed-in power via active power control with a ripple control receiver
Active power control with a ripple control receiver - Limiting the feed-in power via an intelligent metering system (FNN control box)
Active power control using smart measuring systems - Limiting the feed-in power via an intelligent metering system with EEBus
