A new energy harvesting and wireless power transfer system for Smart Grid

The increasing use of online monitoring systems for power transmission and distribution networks has led to new challenges for (i) a reliable energy source and (ii) new techniques for satisfying the simultaneous requirements of high-voltage isolation and high energy efficiency in mid-range power transfer. This paper presents a novel concept of insulation strings with simultaneous functions of high-voltage insulation (HVI) and wireless power transfer (WPT) capability. Resonator coils are embedded in insulation discs, which are connected in series to form the new insulation strings with the HVI and WPT functions. Simulation study on this structure suggests that the proposal is not only feasible but also enjoy high energy efficiency.
