Abstract
China’s renewable resources have the characteristics of reverse distribution, under the background of large-scale development of renewable energy consumption, we should break the existing administrative regional barriers of renewable energy electricity consumption across provinces. In order to accelerate the promotion of renewable energy consumption liability mechanism, an effective curve declaration and clearance model should be proposed. Based on the theory of time-division clearing, this paper makes some improvements in declaration and clearing. Two models are proposed, namely the time-division declaration model and the proportional declaration model. In addition, two clearing methods under different curve declaration decomposition methods are proposed, namely time-division matching clearing method and marginal clearing method. Based on the above theory, the organization methods of power grid and power right transferor and transferee are proposed to promote the optimization of power supply structure and the consumption of renewable energy.

Abstract
Coupling mechanism is one of the key issues in the research of electric vehicle wireless charging system. Single D and DD are two kinds of coupling mechanism commonly used in wireless charging system, and spatial magnetic field distribution are different depending on the coupling mechanism. In this paper, the expressions of magnetic flux density at any point in a single D and DD were derived. A 3D magnetic field measurement platform was built and the magnetic field distribution was drawn. The experimental results show that in the primary test, single D type magnetic induction intensity is 1.18 times of DD type, with the increase of the transmission distance, DD type coupling mechanism of magnetic induction intensity attenuation is slow, and on the secondary side of DD type magnetic induction intensity is 1.12 times of D type.

Published: September 2020

Abstract
Supercapacitor is a new type of energy storage element between traditional capacitor and battery. Particulate leaching method, which was used to increase specific surface area, was the main idea of this article. First of all, GR-PPy material was prepared by chemical in situ polymerization (FeCl3-MO self-degradation template was used to polymerize pyrrole monomer on GR layer). Subsequently, acetylene black and polytetrafluoroethylene emulsion were added and carbon paste electrode was obtained. At the same time, the porous electrode was prepared by particulate leaching method. Cyclic voltammetry, constant current charge and discharge test and AC impedance test were conducted in 1mol· L-1 Na2SO4 electrolyte. The results showed that the specific capacity of the porous electrode was increased by 12% compared with the normal electrode, and the ion diffusion rate was faster than the blank group. In addition, this porous treatment had little effect on the stability of circulation and the electrode resistance. Therefore, it could be concluded that the porous electrode is a promising electrode of supercapacitor.
