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.

This haven't been solved yet? I am using 8.06 version

Hello PVsyst experts, I am working on a project that involves a hybrid grid-connected system with PV and an Energy Storage System (ESS). My goal is to simulate a scenario where the battery is charged every day at maximum capacity (one full cycle per day), with the following objectives: Sell the energy generated by the PV system at a fixed tariff. Sell the stored energy from the ESS according to the pricing of the day-ahead energy market. I want to explore if adding an ESS to an existing PV system is cost-efficient, taking into account the variable market prices for electricity. Currently, PVsyst offers three battery options: self-consumption, peak shaving, and weak grid islanding. However, none of these options seem to fit my case, where the battery would charge daily and sell energy based on market conditions. Could you please advise on how to simulate this scenario in PVsyst, or if there's any workaround that could approximate these conditions? Thanks for your guidance!
