Control algorithm for a residential photovoltaic system with storage
If PV power is higher than the load power (gridflux gf = PV-L < 0), the battery is charged only if its capacity is sufficient to absorb the maximum excess PV energy (MEP). • If PV power is lower than the load power (gf < 0), the battery is discharged. • The system boundaries must be satisfied (battery capacity, inverter power limits).
