Existing converter valve testing methods cannot fully simulate the impact of the turn-on and turn-off of single valves of other bridge arms belonging to the same six-pulse converter. The voltages caused by the turn-on and turn-off processes of the converter valve are different, and existing testing methods cannot provide such voltage waveforms. To solve these two problems, this paper proposes a saturable reactor test circuit topology and a control sequence. A saturable reactor operating condition simulation test platform is established. The simulation and experimental results indicate the effectiveness of the proposed test circuit topology and testing method. © 2023 IEEE.

Firstly, this paper analyzes the mechanism between reactive power and transient voltage of line commutated converter HVdc (LCC-HVdc) receiving-end power grid, and the physical process in three periods is sorted out according to the time scale. The interaction between dynamic load and LCC-HVdc during AC system fault is studied. Based on this, the necessity of dynamic reactive power compensation is proposed. The simulation analysis shows that the dynamic reactive power compensation can effectively improve the transient voltage stability during fault, and can effectively prevent the diffusion of dynamic load transient instability in the heavy load area, and the compensation effect of connected to the low-voltage bus is better than that to the high-voltage bus. The research results of this paper have a significant effect on improving the transient voltage characteristics of LCC-HVdc receiving-end power grid with high proportion of dynamic load, and can guide the actual operation of the project. © ACdc 2022.

By connecting a new type of multi-port energy router in parallel with the tie line between two substations, this paper isolates the regional grid from the main grid. A multi-scenario energy interconnection system is built and three operation modes are introduced: grid-parallel operation, MMC-VSC operation, and off-grid operation modes. Firstly, the topology, secondary system architecture, operation modes and control strategies of multi-port energy router are studied. Secondly, the influencing factors on the smooth implementation of operation modes switching for the energy interconnection system have been examined. Logic of operation modes switching of the energy interconnection system are accordingly proposed. Finally, the simulation results and filed tests show that under the action of the proposed mode switching logic, the system can operate normally at the moment of grid-parallel operation, MMC-VSC operation and both switching times. © 2023 IEEE.

The high voltage shunt capacitor is rated to work at power frequency voltage and current. Due to the existence of harmonic current in power system, the temperature rise of the high voltage shunt capacitor is different from the power frequency condition during stable operation. In order to study the heating characteristics of high voltage shunt capacitors under harmonic conditions, this paper constructs a series equivalent model of high voltage shunt capacitors considering the influence of frequency, and proposes the construction method of solving the electric and thermal field models of capacitors under harmonic conditions. According to the series model, the internal heat source distribution of capacitors is refined, and a full equivalent simulation model of the capacitor thermal field based on electrothermal coupling is built. The simulation model can calculate the capacitor temperature distribution under various current excitation conditions. The heating characteristics of capacitor under power frequency current, single harmonic current and power frequency superimposed single harmonic excitation are simulated and analyzed, and the influence of harmonic on the heating characteristics of capacitor is summarized. © 2024 IEEE.

The flexible HVdc transmission technology based on the modular multilevel converter (MMC) topology has a very broad application prospect in the process of large-scale renewable energy collection and transmission. This technology has become one of the best choices for long-distance offshore wind power farms to connect to the onshore power grid. In view of the special working conditions such as overvoltage in the fault state, this article proposes a controllable large-capacity self-recovery energy-dissipation device for the first time to improve the transient characteristics of the dc and AC power system. The proposed scheme has the advantages of no harmonic generation during operation, relatively simple control strategy and high current impact resistance. The electromagnetic transient simulation shows that the proposed scheme can effectively solve the overvoltage problem of dc in the offshore wind power flexible HVdc system, and improve the reliability of the HVdc system. © 2022 IEEE.

Far-offshore has a wider sea area, larger wind energy reserves and higher quality wind resources, which is an important direction for the future development of wind power. However, with the increasing capacity and area of far-offshore wind farms, the technical and economic problems of far-offshore wind power transmission are becoming more prominent and there is an urgent need for an in-depth analysis of the cost of various far-offshore wind power transmission schemes. Thus, this paper compiles the typical transmission schemes of modular multilevel converter-based high voltage direct current (MMC-HVdc) transmission, low-frequency AC transmission, and full direct current collection and transmission (Full dc) for far-offshore wind power, and proposes a life-cycle cost assessment method by combining the initial investment cost, operation and maintenance cost. Typical cases are selected to construct the topologies of three transmission schemes, and the life cycle economic indexes and transmission distances of these schemes are analysed and compared. Considering a 25-year life cycle, under the case conditions of 1000MW capacity and 100km transmission distance, the total cost of the MMC-HVdc transmission scheme is the highest, followed by the low-frequency transmission scheme, and the full dc transmission scheme is the lowest, saving about 16% cost compared with the MMC-HVdc transmission scheme. © The Institution of Engineering & technology 2023.

The dc power system is a promising solution for the power system of the future due to its advantages in renewable energy and improved grid stability. The dc circuit breaker based on the vacuum interrupter is one of the most important devices in the dc power system. However, it is difficult for vacuum circuit breakers to recover dielectric in the process of interrupting high-frequency and high-current, so it is proposed to connect capacitors in parallel at both ends of the vacuum fracture. In order to study the influence of shunt capacitors on the ability of vacuum circuit breakers to break current, a related experimental circuit is designed. In addition, the effects of shunt capacitance and stray inductance on the rate of change of the reverse voltage are compared horizontally, and the optimal circuit parameters are obtained. It lays a foundation for further research on the vacuum breaking process in the future and improving the reliability of circuit breakers in breaking high frequency and high current. © 2024 IEEE.

Electric tree branches are a typical defect in cross-linked polyethylene high-voltage dc cables, and their initiation and growth will ultimately lead to cable breakdown. And the physical and chemical properties of XLPE will have a certain effect on the growth of dc branches. In this paper, XLPE for AC and dc cable were used to prepare pressed sample pieces, and XLPE samples were obtained from finished AC cables. The physicochemical properties of different XLPE were studied by means of DSC, XRD, GPC. And through electrical tree growth experimental system, the dc tree growth process and partial discharge characteristics of different XLPE needle plate samples were compared and analyzed. The results show that among the three materials, XLPE for dc has the smallest crystallinity, larger grain size, larger relative molecular weight of the polymer, and better resistance to electrical tree branches. And the finished AC cable has higher crystallinity, smaller wafer thickness and close to the polymer relative molecular mass of XLPE for AC, with average resistance to electrical tree branches. © COPYRIGHT SPIE.

Incorporating large-scale renewable distributed generation (RDG) into the power grid introduces significant challenges associated with the indeterminacy of the power system, significantly impacting the comprehensive integration and efficient utilization of the distribution network. This underscores the imperative to investigate scientific evaluation methods and mechanisms for enhancing the RDG absorptive capacity within the distribution network. In light of the stochastic and temporal characteristics inherent to RDG, a novel approach for assessing the RDG hosting capacity within distribution networks is proposed, taking temporal scenarios into account. This method optimizes the RDG output probability distribution model based on its temporal fluctuation change rule, and constructs RDG temporal scenario model by using scenario reduction technology. Subsequently, a temporal scenarios-based RDG hosting capacity assessment model is established, taking into account active network management (ANM) techniques. The effectiveness of the proposed methodology is substantiated through simulation results conducted on a modified IEEE 33-bus system. © 2024 Published under licence by IOP Publishing Ltd.

With the global demand for renewable energy sources on the rise, wind power has emerged as a pivotal form of renewable energy, witnessing rapid expansion in its development and utilization worldwide. This article addresses large-scale wind power transmission scenarios both offshore and onshore. Based on the analysis of technical principles and engineering cost estimation data, it has designed 12 corresponding technical schemes for six advanced wind power collection and transmission methods from both technical and economic dimensions. A scenario with a transmission capacity of 1000MW was selected to conduct a comparative analysis of various types of power transmission technology schemes. The article provides a detailed exposition of the transmission capacity, reactive power compensation requirements, technical maturity, adaptability to scenarios, and economic viability for each scheme, and analyzes the technical and economic characteristics of each scheme. The research results indicate that the diode rectifier transmission scheme has the best economic performance, the VSC transmission scheme is the most technically mature, and the flexible low-frequency transmission scheme has certain economic advantages at medium and short distances. The diode parallel MMC and cascaded MMC schemes are economically second only to the diode rectifier scheme and also have the feature of not requiring wind farm networking. The aim of this paper is to provide guidance for the selection of scaled wind power transmission methods, to promote energy transformation, and to accelerate the construction of a new type of power system.
