How to simulate PV+BESS which can store 75% annual production of PV?

[Jarek]

Hello,
Can anyone help in selecting the simulation parameters of the PV+BESS team so as to obtain a division of STORED 75%, DIRECT USE 25% on the LOSS DIAGRAM?

PV has a power of about 10 MWp and I cannot select the parameters of storage capacity and charging/discharging power to obtain such a result.
I work on a system that uses the PEAK SHAVING storage strategy

Hello Jarek,

Indeed there is no straightforward way to define such a storage strategy system in PVsyst. The final result of the Peak Shaving strategy of course depend on a lot of parameters including the weather conditions on your site, the size of the battery pack, charging/discharging power as well as the grid limitation and discharging strategy. The grid-limitation must be rather restrictive to force the simulation to store the energy in the batteries instead of injecting it to the grid directly. This grid limitation will be the same every hour though so a too strict limitation will risk to hinder the batteries to discharge. 

It is on the roadmap to improve the battery storage strategies, but this is a very complex task and will not be available in the near future. 

Kind regards
