System Output Power Distribution Graph

[amp]

Hi,

I am wondering why some bins associated with higher power injected into grid kW values have a drastically lower Energy injected into grid Mwh associated with them, then power bins with lower values? I understand that each bin has a width of 200kW, and is the sum of all the energy that was produce when the system was operating at the power range for one hour during the entire year.

 

So ex: 1,800kW - 2,000kW -> 44Mwh but 1,600kW - 1,800kW -> 78MWh. Is there any reason why the drastic change? Is it bc of how the inverter operates?

 

Also why on the Y axis it is stated MWh/ class of 50 kW? 

 

Thanks!

There are more hours in the year at one of the power output level compared to another. Filter your 8760 to verify.

50kW is your bin class size, not 200. Count the number of "steps", it is 20 steps to 1000, bin size of 50. The Y axis is MWh per each bin class of 50kW.

The classes are indeed of 50 kW   (this is mentioned on the axis ... since the version 7.2.18! ).

Now I don't have any explanation to this variability, this is a statistical variability.

Eso significa que el sistema funciona más horas a 1800kW que a 2000kW.

Energía= kW x hours

Por las condiciones de la zona, y configuración del sistema, hay más probabilidad a trabajar más tiempo con potencia de salida a 1800kW.

Si a las 2 potencias trabajan la mismas horas, obviamente que a mayor potencia genera más energía.

Saludos!
