In this paper, the use of class $mathrm{E}^{2}$ inverter-rectifier (hereon known as $mathrm{E}^{2}$ converter) system with phase-shift control for bidirectional wireless power transfer applications, is discussed. The system comprises a class E inverter, an active class E rectifier, and a set of wireless transmitter-receiver coils with series-series compensation. The power flow control of the system is achieved via the control of the phase-shift ratio between the driving signal of the inverter and that of the rectifier. To ensure zero voltage switching (ZVS) operation of the converter and precise power flow control over the full load range, the system is designed to be load-independent such that the voltage waveforms of the converter are relatively similar (slight change) regardless of the applied load. The operating principle, time-domain model, and design consideration of the system are elaborated in the paper. Simulation and experimental results are provided as preliminary verification of the derived time-domain model and the features of the system: load-independent output/input voltage waveform of the class E inverter and active class E rectifier over the full load range, ZVS operation over the full load range, providence of bidirectional and sustainable power flow control and accurate output regulation.
本文讨论了带相移控制的$mathrm{E}^{2}$逆变整流器(以下简称$mathrm{E}^{2}$变换器)系统在双向无线电力传输中的应用。该系统由一个E类逆变器、一个有源E类整流器和一组串联补偿的无线收发线圈组成。系统的潮流控制是通过控制逆变器驱动信号与整流器驱动信号之间的相移比来实现的。为了确保变流器的零电压开关(ZVS)运行和在全负载范围内的精确潮流控制,系统被设计成与负载无关,因此无论施加的负载如何,变流器的电压波形都相对相似(略有变化)。本文阐述了该系统的工作原理、时域模型和设计考虑。仿真和实验结果初步验证了所建立的时域模型和系统的特点:E类逆变器和有源E类整流器在全负荷范围内的负载无关的输出/输入电压波形,全负荷范围内的ZVS运行,提供双向可持续的潮流控制和精确的输出调节。

DC microgrids have permeated the energy market in recent years due to the achievement of higher efficiency outputs during power distribution as compared to AC microgrids. Current DC microgrid technology relies on renewable energy sources (e.g. photovoltaic panels, wind turbines) and sub-systems to attain high efficiency while facilitating maximum power point tracking (MPPT) among charge controllers. The key component of a microgrid system is its energy storage system, which assists in mitigating power intermittency due to the deployment of renewables. This paper emphasizes on energy management and control of a DC microgrid system, whereby a simulation model of the proposed DC microgrid is developed in MATLAB/Simulink environment for electrification of a small town. The acquired simulation results have demonstrated feasibility of the proposed DC microgrid during operations.

Nowadays, plug-in electric vehicles (PEVs) have been given wide concerns all over the world due to their merits over the fuel vehicles. Electric vehicle (EV) technology is equipped with a high efficient on-board battery charger (OBC). The battery charger converters are classified into three main types; integrated converter with the machine, two-stage and single-stage structure. These three types of OBC are usually compromised according to power factor corrector (PFC), cost, efficiency and lifetime. In this paper, a recent survey about the various available single-stage isolated unidirectional OBC systems are compared regarding to the previous four metrics. Moreover, hardware limitation, performance, and the utilization of the semiconductors are considered in this review. Finally, those topologies are summarized considering various performance criteria.

As a supplementary part of the droop control, the secondary control is widely utilized in the control of the microgrid, however, its reliability is susceptible due to the possible communication delay and data drop-out. In our recent work, the steady-state amplitude and frequency deviation of voltage can be restored by using the band-pass filter (BPF)-based improved droop control, without any communication links and additional control loop. In this paper, the BPF-based improved droop control is first employed for the two parallel-connected islanded inverters, and its small-signal model is derived in this case. Furthermore, the impact of the active power droop coefficient, the cutoff frequency of high-pass filter and the load impedance on system stability and dynamic performance are further analyzed based on the established model. Finally, the stability and dynamic response performance of the system under different control parameters is compared by simulation in PLECS software, which validates the effectiveness of this method in single-phase inverter system and the derived small-signal model.
二次控制作为下垂控制的补充部分,在微电网的控制中得到了广泛的应用,但由于可能存在通信延迟和数据丢失,其可靠性受到影响。在我们最近的工作中,使用基于带通滤波器(BPF)的改进下垂控制可以恢复电压的稳态幅值和频率偏差,而不需要任何通信链路和额外的控制回路。本文首先将基于bpf的改进下垂控制应用于两个并联孤岛逆变器,并在此情况下推导了其小信号模型。在此基础上,进一步分析了有功功率下垂系数、高通滤波器截止频率和负载阻抗对系统稳定性和动态性能的影响。最后,在PLECS软件中通过仿真比较了系统在不同控制参数下的稳定性和动态响应性能,验证了该方法在单相逆变系统和推导的小信号模型中的有效性。

This paper presents an improved low voltage ride through (LVRT) control strategy for the two-stage photovoltaic (PV) power generation system by adding discharging circuit at the DC-link of the inverter and modifying the active and reactive current reference to the DC/AC inverter when grid voltage sag occurs. The 500kVA two-stage photovoltaic power system model is built in PSCAD/EMTDC platform, which consists of PV arrays, Boost converter and 3-phase DC/AC inverter. The maximum power point tracking (MPPT) control scheme is adopted in the Boost converter, and the dual-loop control structure is utilized for the DC/AC inverter, where the outer voltage loop is used for maintaining DC-link voltage, and the inner current loop is used for improving dynamic response for current tracking. Also, a separate DC voltage loop is adopted in the discharging circuit for the LVRT operation. Simulation in PSCAD/EMTDC platform verifies the validity of the proposed control strategies under symmetrical voltage sag conditions

The future grid encourages distributed energy resources (DER) integration with main power grid to mitigate with the problems of demand-supply mismatch. However for real-time monitoring of voltage profile and line flows it is necessary to continuously run the load flow. However, distribution network (DN) suffers from non-convergence of conventional load flow method (Newton-Raphson) because of high WX ratio. This has motivated to develop a better load flow solution method which will help to address the above mentioned issues with proper allocation of DER for performance enhancement of three-phase unbalance DN. The paper proposes modified forward/backward sweep (FBS) method which helps to identify the weak nodes in network violating the given operating constraints and recommends to implement DERs on such weak nodes to improve voltage profile and reduce stress on power system network. The two-fold contribution of the paper in development of method and performance enhancement is validated using standard IEEE 34 bus which confirms the effectiveness of DERs insertion for three-phase unbalance DN.
未来电网鼓励分布式能源与主电网的整合,以缓解供需不匹配的问题。然而,为了实时监测电压分布和线路潮流,需要连续运行负荷潮流。然而,配电网由于WX比较高,存在传统潮流法(牛顿-拉夫森法)不收敛的问题。这促使开发一种更好的负载流解决方法,这将有助于解决上述问题,适当分配DER以增强三相不平衡DN的性能。本文提出了改进的前向/后向扫描(FBS)方法,该方法可以识别出网络中违反给定运行约束的弱节点,并建议对这些弱节点实施DERs,以改善电压分布,减轻电网压力。采用标准IEEE 34总线验证了本文在方法开发和性能增强方面的双重贡献,证实了三相不平衡DN中der插入的有效性。

This paper presents an impedance-based modelling method for length-scalable long transmission cable (LTC), which is able to assess influence of LTC on stability of grid-connected inverter (GCI). Electrical parameters of power cable in per-unit-length (p.u.l.) are first extracted from the measured terminal short-circuited and open-circuited admittances. Then, the terminal admittance of power cable in different length can be derived on the basis of the obtained p.u.l. parameters. Finally, a decoupled two-port circuit model is established for the LTC using the derived terminal admittance. Simulation results are given to validate effectiveness of the proposed impedance-based modelling method for LTC. The proposed impedance-based modelling method is able to avoid repetitive terminal impedance measurement. Also, the proposed model is able to support impedance-based stability criterion for GCI with length-scalable LTC.

In this paper, the low voltage stress of switches, high voltage gain DC-DC converter is proposed. The operating principle of the converter is similar to that of the conventional buck converter. Therefore, the proposed converter can be operated in the discontinuous conduction mode, continuous conduction mode, depending on the design. Moreover, the controller is also similar to that of the traditional buck converter, results in the simple controller. Furthermore, the voltage stress of every switch is reduced significantly compared with the conventional converter. Therefore, the use of the low voltage rating switches reduces the losses significantly. A 200W converter prototype is successfully built and tested to verify the feasibility of the proposed converter.
本文提出了低电压应力开关、高电压增益DC-DC变换器。该变换器的工作原理与传统的降压变换器相似。因此,根据设计的不同,所提出的变换器可以在断续导通模式、连续导通模式下工作。此外,该控制器也与传统的降压变换器相似,导致控制器简单。此外,与传统变换器相比,每个开关的电压应力显著降低。因此,使用低额定电压开关可以显著降低损耗。成功地建立了一个200W的变换器原型,并对其进行了测试,以验证所提出变换器的可行性。
