“…One of the issues being addressed is analyzing and optimizing the near-field inductive or magnetic resonate coupling WPT [7]- [10]. Another one is improving the power control capability and the WPT efficiency [11]- [18]. Miniaturization of the transmitter and receiver coil is also a major concern [3], [19]- [20].…”

In this study, a metamaterial-coupled, highlyefficient, miniaturized, and long range Wireless Power Transfer (WPT) system based on a Cubic High Dielectric Resonator (CHDR) is explored. The proposed WPT system consists of two CHDR metamaterials separated by a distance and excited by two rectangular coils. Initially, this WPT system is analyzed by considering the cube dielectric permittivity, εr = 1000, and loss tangent, tanδ = 0.00001. From the Ansoft HFSS simulation, it is observed that the system operates in the hybrid resonance mode resonating as a horizontal magnetic dipole providing more than 90% power transfer efficiency at a distance of 0.1λ. In addition, parametric studies regarding the transmitter and receiver sizes, loss tangent, receiver misorientation, cube periodicity, etc. are carried out. One of the significant findings of this parametric study reveals that the suggested WPT system is less sensitive to the displacement of the receiver coil, and the WPT efficiency due to misorientation of the receiver can be increased by changing the CHDR cube rotation. Due to inaccessibility of the very high εr = 1000, eighteen microwave ceramic samples of EXXELIA TEMEX E5080 (Oxide composition: Ba Sm Ti) which has a permittivity, εr = 78, permeability, µr = 1, and a loss tangent, tanδ = 0.0004 was made for experimental verification. These cubes are surrounded by Teflon to make the CHDR resonators. From simulations and measurements, it is found that the proposed system outperforms the most recent high-dielectric or copper based WPT systems in terms of efficiency, range, size, and Specific Absorption Rate (SAR).

In order to schedule the virtual power plant and corresponding energy market operation, a two-scenario Stackelberg game-theoretic model is proposed to describe interactions between market operator and VPP operator. During market operation, the market operator is a leader of the game to decide market cleaning prices, considering the power loss minimization of VPP operator, whereas during VPP operation, the VPP operator becomes a leader to facilitate the demand side management (DSM) through proper monetary compensation, considering the market trading balance between power sellers and power buyers. An optimal scheduling strategy including power dispatch and market balance will be realised. Case studies prove the effectiveness of the proposed Stackelberg game-theoretic model through IEEE 30-bus test system. The market scheduling promotes the power exchange among VPPs. The VPP scheduling evaluates the optimal monetary compensation rate to motivate the DSM including load shifting and load curtailment. Index Terms-demand side management (DSM), game theory, virtual power plant (VPP), distributed energy resources (DERs).
