Optimal power reallocation of large-scale grid-connected photovoltaic

The PV power station surplus power at any time is the difference between the actual power generated and the on-grid power. Thus, the daily surplus power process of the PV power station can be obtained as follows: (2) P y t = P t − P d t where P y is the PV power station surplus power, P is the actual power generated, and P d is the on-grid power.
