hybrid grid-connected system with PV and an Energy Storage System (ESS)

[Theodor]

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:

1. Sell the energy generated by the PV system at a fixed tariff.
2. 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!
