A novel quantum walk-based maximum power point tracking (MPPT) optimization algorithm for stand-alone photovoltaic (PV) system is proposed in this paper. A quantum walk is a quantization of a classical random walk algorithm. Since a classical random walk has proven to be a very powerful algorithmic tool, it is prudent then to investigate its quantum analogue, namely a quantum walk, for design of algorithms. The paper further provides a numerical analysis of the algorithm in order to determine its suitability as an MPPT optimization algorithm. Simulation results show that this quantum walk-based algorithm can quickly reach maximum power point (MPP), thereby reducing PV system power loss.
