An approach to operate high-powered legacy electrical appliances on small scale solar PV systems

In this paper, we propose an approach to operate high-powered legacy electrical appliances on small-scale solar PV. Our proposed method involves a real-time algorithm which detects the onset of a transient and shifts the appliances from PV to the utility during the transient duration. Upon reaching back to a stable state after the transient, the device is shifted back to PV. We have evaluated our transient detection algorithm on a two publically available datasets as well as on a specifically designed testbed system. Our evaluations show that for most common high-powered devices, the transients are detected fast enough to shift the load from PV to the grid and vice versa.
