PV+battery (Optimized) When charging the battery from the grid is allowed, the maximum power extracted from the grid can be minimized. Executing this, the peak load decreases from 220 kW without PV and batteries, to 154 kW with PV and batteries: a peak reduction of 66 kW or 30.0%.
The new peak load occurs on a day with both exceptionally low PV electricity generation and high load. On these days, pre-charging the battery with electricity from the grid can further increase the peak reduction of the combined PV-battery system. Fig.
