Maximum Feed-In Power Clipping

Dear Team:

                  I need to limit the feed-in power at the conection point and I don´t sure if the Máximum feed-in Power Clipping is the tool for that.

For example, if I have a 100 kW PV plant for use in own consumption and I have a feed-in limit of 25 kW, then would I have to put the Máximum Feed-in Power Clipping in 25% of PV Power at the feed in point?

 

Thanks a lot.

 

Regards,

 

Boris

Hi Boris

 

Yes, that is exactly the right option to choose. The Maximum Power Clipping percentage always refers to the installed PV power on the DC side. So if you have 100kWp installed and need to limit your feed-in into the grid to 25kW (on the AC side), you set it to 25%.

 

Whether you clip the power after the inverter or at the feed-in point only really matters if you have loads/batteries/e-vehicles in your system. Energetically of course the best option is to limit the feed-in power at the feed-in point, but not all inverters are capable of doing so.

 

Kind regards,

Martin

HI, I put 31,86 kW on DC side and 71%, because i havent to exceed 22,5 kW on AC side. I get cca 48000 kWh per year. That is in PVSOL Premium. On SMA tool I put 22,5 kW limitation and I get 43000 kwh per year. When I calculate on PVSOL online I get 44132 kwh. On PVSOL online i can't limit.

Hi Dinko,

sorry the for the late answer. These simulation results are very hard to compare, since all tools use different input data, e.g. climate data, different algorithms to model the system components and so on. PV*SOL on you computer and PV*SOL online use the same algorithms, but at the moment the online version uses climate data from an older version of Meteonorm. This will be updated soon.

Kind regards,

Martin
