Handling of Self Consumption and Grid Limitation for Virtual Net Billing Projects

[Theodor]

Hello,

While working on simulations using the Self Consumption option, I have noticed that the results seem to reflect the behavior of a PV system fully integrated into a local installation.

However, in the context of virtual net billing projects, the way the Unused Energy (grid limitation) is calculated does not seem fully accurate. Specifically, the model appears to prioritize the self-consumption of the load first, and only afterwards considers the grid limitation when calculating unused energy.

In virtual net billing schemes, where the PV system is not physically connected to the load but compensation is done financially, this logic does not apply directly. The priority should be given to the grid limitation independently of any local consumption.

Is there any planned feature or workaround to correctly simulate this behavior in PVsyst?
If not, could you please consider implementing an option for such cases in future updates?

Thank you in advance for your support.
