Abstract ：
为抑制微网谐振及母线电压波动,进一步提高直流系统稳定性,该文提出一种计及完全降阶型混合控制算法的直流微网谐振抑制策略.其中,针对线路调节变换器输出电压进行控制,在变换器内环引入电流预测模型,提高系统动态响应速度并省去PWM调制器以及参数的整定,实现电流内环单位化;电压外环则通过构建被控对象逆模型,实现二自由度控制下电压外环单位化.母线电压完全跟随参考电压,抑制了电压传递函数中出现的谐振峰以及母线电压波动现象.最后在Matlab/Simulink平台对所提完全降阶混合控制算法进行仿真验证,结果表明该控制策略能有效抑制直流微网谐振及母线电压波动,提高微网动态特性及抗干扰能力.

Abstract ：
To address issues related to rapid increases in fault currents, high peak values, and the challenge of ensuring reliable power supply in non-fault areas within DC distribution networks, a novel fault current limiter for DC grids is proposed. The limiter design incorporates a bridge circuit to diminish peak fault currents, a coupling reactance for expediting fault transfer, and a primary current-limiting branch that employs pulse-width modulation to suppress fault currents. A coordinated strategy is introduced between the proposed limiter and DC circuit breakers, utilizing voltage differential criteria and directional overcurrent protection. The effectiveness and accuracy of the proposed solution are validated through simulation systems, and preliminary experiments are conducted. Results demonstrate that the proposed limiter effectively curtails fault currents, reducing fault current interruption by at least 90% compared to existing fault isolation methods. This successful implementation of the coordinated strategy ensures the avoidance of converter station lockouts and guarantees the system’s power supply reliability. © 2024 Power System Technology Press.

Abstract ：
The issue of DC fault ride-through can now be resolved in a novel way thanks to flexible current limiting technology, but its practical worth cannot be realized due to flaws in the technology. This study examines the placement of a controlled current source on the secondary side of a current limiting inductor and the enhancement of clamping voltage stability on the primary side of a current limiting inductor from the standpoint of controlling flexible current limiting technology. It offers a theoretical foundation for the specified secondaryside controlled source through an analysis of the iron core's inductance properties. Two-degree-of-freedom algorithm and model predictive control are combined in a control strategy that is appropriate for flexible current limiting devices to address the issue of inadequate response time and control accuracy under standard control. In MATLAB/Simulink simulation software, the presented theory's soundness is lastly confirmed.

Abstract ：
Fault isolation is an important technology to help guarantee that a DC system can be operated stably. A new fault isolation strategy is proposed to improve the traditional strategy which relies too much on a high-performance DC circuit breaker (DCCB). The new strategy makes use of the coordination between a flexible current limiting device (FCLD) and a DCCB. First, the cooperative mechanism between the FCLD and DCCB under permanent fault and transient fault is researched. Second, the arc transient characteristic of the interruption of the DCCB considering suppressed current from the FCLD is analyzed. Finally, a simulation is carried out on the Matlab/Simulink platform to verify the feasibility of the new cooperative strategy. The results show that FCLD can inhibit the breaking arc effectively; with this new fault isolation strategy, the DC system can finish ride through smoothly in the transient fault, while the DCCB can complete the no arc break in the permanent fault. The new strategy has reduced the breaking requirements for DCCB in terms of the DC system’s fault isolation, and improved the fault ride-through capability of the DC system. © 2024 Power System Protection and Control Press.

Abstract ：
In order to solve the problems of weak bidding ability and difficult market accommodation in high proportion wind power market，a bi-level Stackelberg game model of high proportion wind power coupled hydrogen energy storage system participating in spot market bidding is proposed. Firstly，the internal energy conversion relationship of the wind-hydrogen coupling system is studied，and the energy'time-space translation'mechanism of the wind-hydrogen coupling system is revealed. Considering the benefits of the wind-hydrogen coupling system and the cost of wind curtailment，the wind power bidding and hydrogen energy storage charging and discharging decision models are established. Secondly，taking into account the interests of wind- hydrogen coupling system and independent system operators，a market clearing model with thermal power units and wind-hydrogen coupling system as the main body is established based on Stackelberg game. Finally，aiming at the difficulty of solving the two-layer model，the KKT（Karush-Kuhu-Tucker）condition and strong duality theory are used to transform the bi-level model into a single-level mixed integer programming model which is easy to be solved. The simulation results show that the proposed strategy has played a positive role in the market consumption of high proportion of wind power. © 2024 Science Press. All rights reserved.

Abstract ：
直流系统的故障隔离是保证直流系统稳定运行的重要技术。针对传统故障隔离策略对直流断路器(direct current circuit breaker, DCCB)的性能要求较高的问题，提出了一种利用柔性限流装置(flexible current limiting device,FCLD)与DCCB协同动作的故障隔离策略。首先，研究了直流系统永久性故障和瞬时性故障情况下FCLD与DCCB的协同作用机理。其次，分析考虑FCLD电流抑制作用下DCCB开断过程的电弧暂态特性。最后，在Matlab/Simulink平台中进行仿真，验证所提协同策略的可行性。结果表明：FCLD可有效抑制DCCB的开断电弧；基于所提故障隔离策略，直流系统可在瞬时故障情况下实现平稳穿越，永久故障情况下实现DCCB的无弧开断。该策略降低了直流系统故障隔离过程中对DCCB的开断要求，提升了直流系统的故障穿越能力。
