In this article, a new type of bidirectional DC-DC converter with ultra-high voltage conversion capability applied in the field of energy storage systems is proposed. The new converter consists one inductor, two capacitors, and four power semiconductors. Compared with the traditional buck-boost converter, the proposed topology doubles the effective duty cycle, and can obtain a higher voltage gain without using extreme duty cycles. In addition, lower voltage stress of semiconductor devices can also be achieved. The control strategy is uncomplicated due to the simple structure. The steady-state analysis and small signal analysis of the topology in continuous conduction mode are introduced in detail, and the voltage stress of the components in the topology is deduced. The novel structure compared with the structure in the existing literature, it shows the excellent performance of the proposed converter. Finally, a 4S-400V/400-48V simulation model was established to verify the reliability and correctness of the proposed topology.

Emergency load shedding (ELS) is an essential measure to keep system stability. Due to the high cost of load shedding, minimizing the amount is always the goal while satisfying security requirements. The optimization problem is highly nonlinear and can be solved with heuristic algorithms by generating a large number of candidates. However, it is time-consuming to check the feasibility of each candidate by numerical simulation. To address this issue, this paper presents an accelerated ELS optimization method based on surrogate-assisted differential evolution (SADE). The optimization process is driven by differential evolution (DE). Radial basis function (RBF) neural network is adopted as the surrogate model to replace the numerical simulation for checking the security constraints. Only the most promising candidates pre-screened by RBF are evaluated by numerical simulation. The validity of the proposed ELS optimization method is verified with a provincial power system.

Due to Direct Current (DC) has no periodic zero crossing, the arc is difficult to extinguish by itself. To prevent grounding insulator surface flashover, a protective gap is set on the grounding insulator. The Claw arcing horns are one of the protection gap devices and produce DC arc. In this study, the simulation model of Claw arcing horns is established, based on the Magneto Hydro Dynamics (MHD) theory. The arc development characteristics are analyzed, which is of maximum temperature and the corresponding time. The simulation results show that the minimum distance of its installation gap and the material of its electrode have a great influence on the DC arc. When the gap minimum distance between the gaps of its electrodes increases, the temperature of arc changes regularly. The minimum gap distance for this model is 3.5 mm. And the Claw arcing horns are made of copper, which is conducive to arc extinguishing. This study has guiding significance for the structural design and material selection of the arc extinguishing horn in DC grounding system.

This paper addresses a fast frequency support scheme of a doubly-fed induction generator (DFIG) based on overspeed de-loaded curve that is able to boost the frequency nadir and settling frequency, and reduce the maximum rate of change of frequency (ROCOF) with more efficiency. To address this, a novel power function is employed that increases the power to the torque limit and then decreases with the rotor speed toward to the maximum power point tracking operating conditions. Simulation results on various wind power penetrations clearly indicate that the proposed fast frequency support scheme is benefit to boost the frequency nadir and settling frequency, and reduce the ROCOF.

With the gradual transformation of the energy structure, energy storage has become an indispensable important support and auxiliary technology for low-carbon energy systems. The development of electrochemical energy storage technology has advanced rapidly in recent years. Cost reduction, technological breakthroughs, strong support from national policies, and power market reforms have created favorable conditions for the commercial application of electrochemical energy storage technology. However, energy storage, which has attracted much attention, is an emerging industry with great uncertainty, and its development is full of opportunities and risks. The article uses the SWOT model to analyze the commercial application of electrochemical energy storage, and summarizes a variety of internal and external factors that affect the commercial promotion of electrochemical energy storage. Then a case study of Xinjiang wind plant energy storage configuration is used to illustrate that electrochemical energy storage systems can participate in a variety of service application scenarios and achieve significant benefits. Our work provides a reference for companies to formulate strategic plans for energy storage projects, and puts forward suggestions on the commercialization and largescale development of the energy storage industry.

Switched capacitor network has been widely used in power electronic circuits. Under the same input voltage and switch duty cycle, buck-boost converter with switched capacitor network can achieve better voltage-drop effect. Based on peak current controlled buck-boost converter with switched capacitor network, a model of discrete iterative mapping, this paper studies the entropy characteristics to analyze the nonlinear dynamic behavior of the converter. First, two-dimensional entropy of the converter is obtained, which reflects the overall statistical characteristics. Then, the numerical sequence distributions of buck-boost converter with switching capacitor network are also analyzed under different load resistors.
