In this paper, two types of Silicon (Si) IGBT and Silicon Carbide (SiC) hybrid switch (Si/SiC HyS) based three-level active neutral-point-clamped (3L-ANPC) inverter are proposed for high efficiency and low device cost. The proposed Si/SiC HyS-based 3L-ANPC inverters are compared with the full Si IGBT, full SiC MOSFET, and Si with SiC devices-based hybrid 3L-ANPC solutions on the inverter efficiency, power capacity, and device cost. It is shown that compared with the full Si IGBT 3L-ANPC solution, the inverter efficiency improvement by Si/SiC HyS is 2.4% and 1.8% at light load condition and heavy load condition, respectively. Compared to the full SiC MOSFET solution and 2-SiC MOSFET hybrid scheme, the device cost of 2-Si/SiC HyS-based 3L-ANPC is reduced by 78% and 50% with 0.28% and 0.21% maximum inverter efficiency sacrifices. The testing results show that the proposed Si/SiC HyS-based 3L-ANPC inverter is a cost-effective way to realize high inverter efficiency. Between the two proposed Si/SiC HyS-based 3L-ANPC inverters, the 2-Si/SiC HyS-based 3L-ANPC inverter has lower device cost which makes it more suitable for cost-sensitive and high efficiency applications. While the 4-Si/SiC HyS-based 3L-ANPC inverter has higher output power capacity, making it a better candidate for high power density, high power capacity, and high efficiency applications.
本文提出了两种基于硅(Si)IGBT和碳化硅(SiC)混合开关(Si/SiC-HyS)的三电平有源中性点箝位(3L-ANPC)逆变器,以实现高效率和低器件成本。将所提出的基于Si/SiC-HyS的3L-ANPC逆变器与基于全硅IGBT、全SiC-MOSFET和硅与SiC器件的混合3L-ANPC解决方案在逆变器效率、功率容量和器件成本方面进行了比较。结果表明,与全硅IGBT 3L-ANPC解决方案相比,在轻负载和重负载条件下,Si/SiC-HyS的逆变器效率分别提高了2.4%和1.8%。与全SiC MOSFET解决方案和2-SiC-MOSFET混合方案相比,基于2-Si/SiC-HyS的3L-ANPC的器件成本分别降低了78%和50%,最大逆变器效率牺牲了0.28%和0.21%。测试结果表明,所提出的基于Si/SiC-HyS的3L-ANPC逆变器是实现高逆变器效率的一种经济有效的方法。在所提出的两种基于Si/SiC-HyS的3L-ANPC逆变器之间,基于2-Si/SiC HyS的3L-ANP逆变器具有较低的器件成本,这使其更适合于成本敏感和高效的应用。而基于4-SiC/SiC-HyS的3L-ANPC逆变器具有更高的输出功率容量,使其成为高功率密度、高功率容量和高效率应用的更好候选者。

Flexibility from demand-side resources is increasingly required in modern power systems to maintain the dynamic balance between demand and supply. This flexibility comes from elastic users managing controllable loads. In this context, controlling Electric Space Heaters (ESHs) is of particular interest because it can leverage building inner thermal storage capacity to shift consumption while maintaining comfort conditions. Some economic Demand Response (DR) programs have considered exploiting EHSs flexibility potentials in recent years. However, these programs still struggle to engage customers due to the complexity of processing price signals for inexpert users. Therefore, it is necessary to develop automated tools for helping users to operate their loads. Accordingly, this paper presents a recommender system based on Gaussian processes to discover users’ valuations of thermal comfort and perform the predictive control of their ESHs. The proposed method enables customers to participate in DR programs and impose their preferences through straightforward queries instead of directly changing control parameters. Validation results demonstrate that users maximize their utility by supplying noiseless and consistent data to the recommender system. Additionally, the suggested approach achieves a higher acceptance rate than other methods from the literature, such as persistency and support vector machines.
现代电力系统越来越需要需求侧资源的灵活性,以保持需求和供应之间的动态平衡。这种灵活性来自于弹性用户管理可控负载。在这种情况下,控制空间电加热器(ESH)特别令人感兴趣,因为它可以利用建筑物内部的储热能力来改变消耗,同时保持舒适条件。近年来,一些经济需求响应(DR)项目已经考虑开发EHS的灵活性潜力。然而,由于为不熟练的用户处理价格信号的复杂性,这些程序仍然难以吸引客户。因此,有必要开发自动化工具来帮助用户操作负载。因此,本文提出了一种基于高斯过程的推荐系统,以发现用户对热舒适性的评价,并对其ESH进行预测控制。所提出的方法使客户能够参与DR计划,并通过直接查询而不是直接更改控制参数来强加他们的偏好。验证结果表明,用户通过向推荐系统提供无噪声和一致的数据来最大限度地提高他们的效用。此外,所提出的方法比文献中的其他方法(如持久性和支持向量机)获得了更高的接受率。

This paper proposes a novel and robust version of Model Predictive Control scheme for AC drives based on Voltage Source Inverter (VSI) with Active Front End (AFE). The main feature of the proposed MPC is elimination of Common Mode Voltage (CMV) without imposing a penalty on the corresponding term in the cost function, but rather by a smart utilisation of the restricted set of switching states in a computationally efficient algorithm. Furthermore, the paper proposes to split the conventional MPC scheme into separate Control and Modulation stages, and to enhance the Control stage by integral action, and the Modulation stage - by a Feedback Quantizer. The resulting AC drive scheme provides high tracking accuracy over the full speed range, robustness to disturbances and parameters error, coupled with practically zero CMV and consequently - very low levels of conducted and radiated electromagnetic interference (EMI). This makes the proposed scheme a competitive alternative to the existing AC drive solutions in the most challenging industrial applications. The benefits of the proposed scheme are validated by simulation and experiment.
本文提出了一种基于有源前端电压源逆变器(VSI)的交流驱动器模型预测控制方案。所提出的MPC的主要特征是消除共模电压(CMV),而不对成本函数中的相应项施加惩罚,而是通过在计算高效的算法中智能地利用开关状态的受限集合。此外,本文还提出将传统的MPC方案拆分为单独的控制和调制级,并通过积分作用来增强控制级,通过反馈量化器来增强调制级。由此产生的交流驱动方案在全速范围内提供了高跟踪精度、对干扰和参数误差的鲁棒性,加上几乎为零的CMV,因此传导和辐射电磁干扰(EMI)水平非常低。这使得所提出的方案在最具挑战性的工业应用中成为现有交流驱动解决方案的有竞争力的替代方案。仿真和实验验证了该方案的优越性。

A microgrid is a proven effective way to integrate renewable resources. This study presents an innovative control concept for decentralized AC microgrids, which is based on the architectural advantage of a radial microgrid structure. Under the proposed concept, power sharing between the distributed sources is achieved without droop control. Thus the need for a secondary control level is eliminated. Moreover, the use of explicit communication is replaced in the paper by a novel coordination mechanism based on the locally measured currents. The paper shows that, with a special design of the current control of grid-feeding converters, the proposed microgrid automatically provides equitable sharing of the load demand amongst the distributed generators (DGs). Moreover, the dynamic responses of the DGs are identical and decoupled from one another. It is further shown that the proposed AC microgrid is stable in the presence of any type of load. The findings of the paper are validated by simulations and laboratory experiments.

The hybrid-voltage-source three-level inverter is a traction circuit system aimed at realizing energy savings with lithium-ion batteries for direct-current-electrified railway vehicles. However, this system has the limitation of being unable to freely control the power flow of the batteries owing to the pulse width modulation. However, because this system has batteries, energy management is required for the batteries. Therefore, it is necessary to propose an energy-management method that achieves the required energy-saving effect while considering the constraints of the battery power control. In this paper, a management method is proposed to control the power flow of the batteries by determining the pulse mode of the inverter and the modulation wave offset based on the state of the charge and inverter frequency. In a 0.75-kW class mini-model verification, the effectiveness of the proposed energy-management method is then confirmed based on the state of the charge, inverter frequency, offset, and battery power. Subsequently, we evaluate the energy-saving effect of this hybrid system using a numerical simulation while considering an actual railway vehicle. In addition, the optimal capacity of the batteries is investigated. As a result, the best energy-saving effect is obtained when two of the assumed batteries are connected in series and three in parallel, and the power consumption is reduced by approximately 21%.
混合电压源三电平逆变器是一种用于直流电气化铁路车辆的牵引电路系统,旨在利用锂离子电池实现节能。然而,由于脉冲宽度调制,该系统具有不能自由控制电池的功率流的限制。然而,由于该系统具有电池,因此需要对电池进行能量管理。因此,有必要提出一种在考虑电池功率控制约束的同时达到所需节能效果的能量管理方法。本文提出了一种管理方法,通过根据充电状态和逆变器频率确定逆变器的脉冲模式和调制波偏移来控制电池的功率流。在0.75-kW级小型模型验证中,基于充电状态、逆变器频率、偏移和电池功率来确认所提出的能量管理方法的有效性。随后,我们在考虑实际铁路车辆的情况下,通过数值模拟评估了该混合动力系统的节能效果。此外,还对电池的最佳容量进行了研究。结果,当假设的电池中的两个串联连接,三个并联连接时,获得了最佳的节能效果,并且功耗降低了约21%。

On Medium Frequency Differential Mode Resonance Effects in Doubly Fed Induction Machines 双馈异步电机的中频差模谐振效应

During synchronization phase of a doubly fed induction machine prototype abnormal high voltages were recorded at stator terminals. By evaluating the measured curves, and the frequency response of a similar machine, these overvoltages could be traced back to differential mode resonance effects within the machine itself. The effect of differential mode resonance is not restricted to doubly fed induction machines but also occurs in other machine types such as squirrel cage induction machines. If not considered in the insulation design, such abnormal voltages will lead to a premature ageing of the insulation. Depending on the operating conditions, premature failures may occur. The measured data presented in the article give an illustrative example what could happen if windings of electric machines are excited near series resonance frequency. As the occurence of this effect becomes more probable the higher the switching frequency of the converter, it is thoroughly important to be aware of it.
在双馈异步电机原型的同步阶段,定子端子处记录到异常高电压。通过评估测量曲线和类似机器的频率响应,这些过电压可以追溯到机器本身的差模谐振效应。差模谐振的影响不仅限于双馈感应电机,也发生在其他机器类型中,如鼠笼式感应电机。如果在绝缘设计中不考虑,这种异常电压将导致绝缘过早老化。根据操作条件的不同,可能会发生过早故障。文中给出的测量数据举例说明了如果电机绕组在串联谐振频率附近被激励会发生什么。随着转换器的开关频率越高,这种影响发生的可能性就越大,意识到这一点非常重要。

The growing wave energy sector requires an efficient and flexible testing process for the development phase of wave energy systems. Real-time hybrid testing is a promising technique for the accelerated testing of wave energy conversion systems. This article presents an experimental study on developing a hybrid testing platform for wave energy systems at the Wallace Energy System and Renewables Facility (WESRF) at Oregon State University. The wave energy conversion system is broken down into numeric (i.e., virtual) and physical (i.e., hardware) components. The numeric component involves software components such as the control algorithm for Wave Energy Converter (WEC) and controller for the power electronic converters and numerical models for the WEC device hydrodynamics. The hardware involves an ocean wave emulator testbed, Power Take-Off (PTO) mechanism, power electronics, and instrumentation. The numeric components are implemented in a real-time target machine and are interfaced with the experimental system. A case study implementation of Nonlinear Model Predictive Control (NMPC) is presented for a single degree of freedom heaving nonlinear WEC model with a Permanent Magnet Synchronous Generator (PMSG) as a PTO system. A Field-Oriented Control (FOC) algorithm controls the PMSG-PTO generation using a three-phase Integrated Intelligent Power (IIP) module converter. A demonstration of the proposed hybrid testing setup is provided.
