Recently, the micro-grid concept has been widely discussed and it is anticipated to be a key player for future power grid. Nevertheless, students often find micro-grid knowledge too complicated to comprehend with due to lack of real-life working examples. In this paper, we propose a new educational simulation platform to teach micro-grid technology with the help of the latest Electrical Transient and Analysis Program (ETAP). This fully integrated software has capabilities in planning and operating the electric grid with power monitoring and system optimization tools available for all project scales with high flexibility. A benchmark 0.4 kV low-voltage micro-grid including photovoltaic arrays and wind turbines generators is used both in grid-connected mode and island mode in this paper. Students can input different system parameters on static and dynamic components; the software can then conduct various simulations for further analysis. This paper will illustrate the use of power flow analysis and transient stability analysis. Students would learn more about the system outcome with result analyzer and alert view function on the result display interface. In short, this simulation platform is a valuable learning resource for students and it has a significant implication to the industry as well.
近年来,微电网的概念得到了广泛的讨论,并有望成为未来电网的关键角色。然而,由于缺乏实际的工作实例,学生们经常发现微电网知识过于复杂而难以理解。在本文中,我们提出了一个新的教育模拟平台,借助最新的电瞬变与分析程序(ETAP)来教授微电网技术。这种完全集成的软件具有规划和操作电网的能力,具有高度灵活性,可用于所有项目规模的电力监控和系统优化工具。本文采用了包括光伏阵列和风力发电机组在内的基准0.4 kV低压微电网并网模式和孤岛模式。学生可以在静态和动态组件上输入不同的系统参数;然后,该软件可以进行各种模拟以进行进一步分析。本文将说明潮流分析和暂态稳定分析的应用。学生可以在结果显示界面上使用结果分析器和警告视图功能来了解更多的系统结果。总之,这个仿真平台对学生来说是一个宝贵的学习资源,对行业也有重要的意义。

This paper presents a modular, scalable and viable architecture for a DC Microgrid to supply electrical power to off-grid communities, particularly in developing countries, where grid electricity is unavailable or is largely intermittent. We have modeled a system for a 40 house village where each house generates (through PV), stores and can share electrical energy with the community for an optimized system. The concept is then extended to an islanded DC Microgrid model with scalable renewable generation and smart power regulation. This paper also includes the operational analysis of the proposed microgrid architecture using Newton Raphson method modified for DC grid analysis. This analysis is used to optimize the voltage level for regulation, efficiency and safety. The results are then verified through an experimental setup in the laboratory. Lastly, this paper also proposes a protection scheme for the DC microgrid and the contributing households.

Because the dynamics of synchronous generator relates to the stability of power system closely, there is growing concern about estimating the status of synchronous generator when disturbances occur in power system. This paper employs Set Membership Filter based on DC Programming (SMFDC) for estimating the states of synchronous generator, by using local measurements of each generation unit. The estimator only assumes the process and measurement noises are bounded without any other statistics assumptions. By transforming the estimation model to Deference of Convex (DC) function form, the problem of bounding the linearization errors can be convert to solve DC programming, which is different from the interval analysis method in ESMF. To compare with ESMF [20], the estimation results of SMFDC are better and the estimator makes a great improvement in real-time property.
由于同步发电机的动态特性与电力系统的稳定性密切相关,因此在电力系统发生扰动时同步发电机的状态估计问题越来越受到人们的关注。本文采用基于直流规划的集隶属度滤波(SMFDC)方法,利用各发电机组的局部测量值来估计同步发电机的状态。该估计器仅假设过程和测量噪声是有界的,不需要任何其他统计假设。通过将估计模型转化为差分函数形式,可以将线性化误差的边界问题转化为求解线性化规划问题,这与ESMF中的区间分析方法不同。与ESMF[20]相比,SMFDC的估计结果更好,估计器的实时性有很大提高。

Power efficiency delivered from a PV panel individually or as larger system for example a PV Solar Form is very much dependent upon many factors for example irradiance, temperature, shadowing and the health of individual PV panels/cells. The first two factors are typically beyond the control of designer/engineers but certainly if we can determine shading and early diagnoses about the health of a panel/cell we can quickly fix such issues so that system delivers normal power production for which it is designed and maintains the required power efficiency.
单个PV板或更大系统(例如PV Solar Form)提供的功率效率在很大程度上取决于许多因素,例如辐照度、温度、阴影和单个PV板/电池的健康状况。前两个因素通常超出了设计师/工程师的控制范围,但如果我们能够确定阴影和对面板/电池健康状况的早期诊断,我们可以快速解决这些问题,以便系统提供正常的电力生产,并保持所需的电力效率。

Virtual-flux-based predictive direct power control of three-phase AC/DC converters 基于虚拟磁通的三相AC/DC变换器预测直接功率控制

In this paper, a novel predictive direct power control (PDPC) strategy is proposed for three-phase AC/DC converters, which is based on a straightforward regulation of instantaneous active and reactive power. The converter controlled by the proposed strategy realizes operations without line-side voltage sensors by introducing the virtual flux (VF) concept and a grid voltage estimation method based on the instantaneous power. A constant converter switching frequency is achieved by employing the space vector modulation, which simplifies the design of the line filter. Simulation results show that the improvement of power ripple elimination and sinusoidal line currents can be observed in the proposed PDPC at a lower switching frequency. Comparative studies reveal that the steady behaviors of the proposed PDPC are superior to that of the conventional look-up-table DPC (LUTDPC) and PDPC, moreover the transient process of which is more shorter compared with that of the conventional LUTDPC.

It has long been a hot issue of the single-phase to ground fault identification technics for the distribution network with neutral un-grounded system (NUS), the neutral resonant grounded system (NES) and the neutral resistor grounded system (NRS). The fault detection and location could be very difficult since the faulted component in above scenarios is less pronounced, and meanwhile it becomes a less helpful by using conventional scheme if the arc suppression coil is equipped. In this paper, a novel method based on the neutral point medium resistance switching-on is introduced, and the faulted component of the lines in the distribution network is analyzed. By the comparison between the variations of the faulted phase-current before and after the medium resistance switching-on, the faulted location can thus be determined. Simulation results indicate that in most cases, the proposed method show great reliability and immune to the changes of the system conditions.
中性点不接地系统(NUS)、中性点谐振接地系统(NES)和中性点电阻接地系统(NRS)配电网单相接地故障识别技术一直是一个热点问题。由于上述情况下的故障部件不太明显,因此故障检测和定位非常困难,同时如果采用常规方案,如果配备消弧线圈,则帮助不大。本文介绍了一种基于中性点介质电阻分闸的新方法,并对配电网中线路的故障成分进行了分析。通过比较介质电阻接通前后故障相电流的变化,可以确定故障位置。仿真结果表明,在大多数情况下,该方法具有较高的可靠性,且不受系统条件变化的影响。

Original last breaker protection based on arrester energy consumption characteristics might malfunction in light loaded power system. In this paper, we analyzes the relationship between the high side inlet voltage of converter transformer and the AC load, pointing out that the main reason of the arrester based last breaker protection maloperation is that the original protection strategy cannot distinguish light load state from isolation state of the AC line. This paper adds outlet head end voltage and output power to the original criterion, designs an improved one so that it can correctly distinguish what state the AC line and send the right signals for different action status. Simulate and analyze the act of original criterion and improved one in light loaded power system by using the simulation model which is built based on the actual operating parameters of Yunnan-Guangdong UHVDC project, validating the improvement of novel criterion.

Electromechanical oscillations one of the most important stability limits constraining power transfer between two countries. This paper presents different power system electromechanical oscillation types, and focuses on inter-area oscillation, where SVC is chosen to be installed at the midpoint of long tie line between Iraq and Turkey, so as to be more effective for two options: the first option is to use the SVC for inter-area oscillation damping, in case of system oscillation occurring in a 3-ph-to-ground short circuit fault at the tie transmission line between countries near the exporting area which is removed after 100ms, and the second option is to use it as a voltage regulator of this long transmission line. The control operation of the SVC is accomplished with the control signal from remote control unit such as WAMS. By using Matlab and Simulink, different simulation results are presented based on various scenarios.

This paper analyzed the principle and performance characteristics of PR controller, and proposed a control strategy based on improved PR controller of direct-driven permanent magnet synchronous wind power generation system. Instead of the traditional PI controller, improved PR controller is used to saving a coordinate transformation, eliminating the cross-decoupling terms and feed-forward compensation items, and simplifying the control algorithm. The introduction of improved PR controllers has superior performance in permanent magnet synchronous motor control system, it can realize no static difference to the AC input signal. For validation, simulation model is built to experiments and analysis.
分析了PR控制器的工作原理和性能特点,提出了一种基于改进型PR控制器的直驱永磁同步风力发电系统控制策略。采用改进的PR控制器代替传统的PI控制器,省去了一次坐标变换,消除了交叉解耦项和前馈补偿项,简化了控制算法。改进的PR控制器在永磁同步电机控制系统中具有优越的性能,可以实现对交流输入信号的无静态差分。为了验证,建立了仿真模型进行实验和分析。
