I need to fill out a compliance paper for an on grid ESS solution with Multiplus version one, and an anti islanding device.
The question I need to find out is what is the minimum active effect that can be exported to the grid when there is an overfrequency, say 51,5 hz. So just before it cuts off. How does the curve look? I know that the multiplus lowers the exported effect when an overfrequency occurs. But how much. Is it linear? The multipluses are a 3 phase configuration with 3kva models.
