This paper explores the effect of the shielding plate in the inductive power transfer (IPT) pads, and identify its impact on leakage magnetic field and pads losses. The 3-D finite-element analysis method is used to optimize the structure of the shielding plate. The shielding effectiveness is investigated in terms of thickness of the shielding plate, air-gap distance between the shielding plate and the ferrite plate, covering area and geometry of the shielding plate. The result shows that the shielding structure plays dominant role in leakage magnetic field and pad losses. By using the optimized shielding structure, both the leakage magnetic field in the vicinity of the WPT system and the power loss in the transmission pads are reduced, which provides a reference of shielding structure design for IPT systems.

The black start process is an abnormal special operation mode of power grid operation and the working conditions are complex, and there are often unexpected accidents and problems in the start-up process, especially the impact of different auxiliary machines driven at the load recovery stage on the system is very different, and the ordinary black start simulation results are not accurate enough. To this end, a black start model considering a single power supply to drive a variety of auxiliary machines is proposed. The auxiliary start-up stage of the nearby power plant after the successful black start is modeled, and the black start scheme is analyzed and evaluated from the three main aspects of generator self-excitation, no-load line over-voltage and low-frequency oscillation, and the transient response characteristics in the black start process are clearly displayed in the form of waveform diagram, which is used as a strong basis for judging whether the corresponding black start scheme of the model is safe and reliable.

Preventive maintenance strategy is an important mean to ensure the reliable operation of large equipment in power plant, nuclear power plant, high-speed railway Electric Multiple Units (EMU) and other fields. Aiming at the problems of high maintenance cost and great damage of EMU gearbox, the reliability and state maintenance decision model based on stochastic differential equation (SDE) and Copula theory was proposed in this paper. Firstly, the model comprehensively considers the degradation process of components and the external random disturbance factors, describes the external random disturbance by Brownian operation, and establishes the Weibull proportional risk model based on SDE. Secondly, based on Copula theory, the reliability model of component performance degradation is obtained. On this basis, the corresponding Time-Based Maintenance (TBM) and Condition-Based Maintenance (CBM) strategies are established, and the preventive maintenance strategy of components is formulated with the optimization goal of minimizing cost ratio. Finally, the example is given to analyze the reliability model and verify its validity.

With the development of new energy equipment such as electric vehicles, the large-scale integration of charging piles and charging stations into the integrated energy system has brought a lot of volatility and randomness to the system load, which can be solved by installing multi-energy energy storage facilities. This paper proposes a multi-energy energy storage planning method for integrated energy systems that considers load uncertainty. By characterizing the load uncertainty, combined with the established multi-energy energy storage planning model of the integrated energy system, the optimal capacity of the energy storage facility is obtained for the economical optimization.
