Hi,
Some european energy dealers offer to store produced energy on the grid in a virtual battery so that the client can use it at night or on peak load.
It works this way :
- Every month you rent a virtual storage capacity from 100 kWh to 1800 kWh
- Solar energy produced is self consummed by the client, the excess is injected in the grid and counted , it is not buyed, it is just counted
- If the amount of energy injected is above the storage capacity, the energy is given to the grid
- When client needs more power than the array is producing, it is supplied by the grid but is consumming virtual storage first with no cost
- When storage is empty, it is supplied by the grid
I tried to simulate this by creating a fake wonder storage but results are a bit tweaky. This king of virtual storage has no load time, nor efficiency. Is PVSyst able to simulate this ?
Thank you !
