Wind power generation is an attractive renewable energy technology that promotes the reduction of greenhouse gases. Nevertheless, the inherent alternating nature of wind power affects the stability of the grid as it results in frequency variations, voltage deviations, and increased ramp rates. Battery Energy Storage Systems (BESS) are incorporated in the microgrid to alleviate the aforementioned issues and to promote optimal operation by reducing the power fluctuations. Additionally, power firming filters and algorithms are also combined with the batteries for ramp rate curtailment, power flattening, and cost reduction. Widely used filters such as Low Pass Filters (LPF) and Moving Average (MA) filters are capable filters for fluctuating power control but have poor power tracking capabilities. To account for the resultant power lag, bigger batteries are needed which increases the operating costs. This paper presents a Hodrick Prescott Decomposition filter for wind power firming and enhanced power tracking. Simulation results conclude that the proposed methodology has significantly better power flattening and tracking capability than both the LPF and MA filters. As compared to the traditional filters, the proposed filter leads to decreased battery charging/discharging and appropriate state of charge control which in turn reduces the size of the batteries required for optimal operation.

The growing deployment of electric vehicles (EVs) in the utility grid raises concerns regarding the current distribution infrastructure's capability to accommodate such a rapidly increasing load demand. This paper presents a methodology for modeling and simulating EV charging demand in residential distribution systems. The modeling approach can be used to study the impact of unscheduled charging and also for energy management studies. Since each driver or a group of drivers has a particular behavior, the daily EV plug-in profile variations are characterized to show the individual driving behavior. This approach is more suitable for energy management studies and charging coordination algorithms. The impact of unscheduled charging is investigated using the IEEE 13- Node Test Feeder with 601 EVs, which represents a 50 % penetration level. Tesla Model 3 EV is used, and the 13- Node Test Feeder is simulated in the MATLAB software. Statistical studies, using a year worth of data, show the significant effect of unscheduled charging on the quality of the distribution system operation. Feeders that are impacted the most in terms of violating the voltage limit and current limits are highlighted, and the violation statistics are presented.
越来越多的电动汽车(ev)在公用电网中的部署引起了人们对当前配电基础设施是否有能力适应如此快速增长的负载需求的担忧。本文提出了一种住宅配电系统中电动汽车充电需求的建模和仿真方法。该建模方法可用于研究非计划充电的影响，也可用于能源管理研究。由于每个驾驶员或一组驾驶员都有特定的行为，因此对EV插件的日常配置文件变化进行表征以显示个人驾驶行为。该方法更适合于能源管理研究和充电协调算法。使用IEEE 13节点测试馈线(IEEE 13- Node Test Feeder)对非计划充电的影响进行了研究，其中601辆电动汽车的渗透率为50%。以特斯拉Model 3 EV为例，在MATLAB软件中对13节点馈线器进行了仿真。统计研究，利用一年的数据，显示了计划外收费对配电系统运行质量的显著影响。突出显示了违反电压限值和电流限值影响最大的馈线，并给出了违反统计数据。

In recent years, the use of wind energy in the world has grown. Consequently, the need for studies related to the impact of wind turbines on the electrical system has increased including protection of them and associated equipment. For DFIG-based wind turbines, differential protection has recently been proposed, however, there are few studies on this type of application and in this paper it proposes criteria in the decision-making using the Park transform in which, in addition to the restriction current, voltage level and current direction at the stator terminals are considered. In a DFIG operating with 1.51 MW tests of faults internal and external to the protection zone were made, of the single-phase and three-phase type with various levels of voltage drops. Interturn faults in the rotor and stator of the machine were also tested with various levels of defects. So, with the proper definition of the operating logic, it was possible to show the effectiveness of the protection.

Distributed Energy Resources (DERs) are proliferating in distribution systems across most jurisdictions. As distribution system operators work towards interconnecting DERs, they experience new issues that require thorough assessment and mitigation. Among these issues, one such example is coping with intensified Temporary Overvoltage (TOV) on un-faulted phases that results from a system reconfiguration that causes the distribution system to no longer be effectively grounded. In particular, inverter-based DERs and/or certain preferred step-up transformer configurations lead to worse TOV levels than those experienced in typical distribution systems pre-DER connection. TOVs pose insulators and surge arrestors at risk. Currently, there remains a gap in distribution planning of most jurisdictions in formulating the aspects of performance grounding and adopting simple and practical measures to overcome the challenge. This paper provides an overview and analytical evaluation of TOVs in modern distribution systems with high DER penetration and introduces mitigation options, including assessment and design procedures of effective ground sources. Two real distribution systems of a Canadian electric utility are presented as case studies to illustrate the problem definition and proposed mitigation strategies adopted in the project execution.

The overhead distribution transformer is one of the most important and expensive equipment in the distribution grid. Without the proper monitoring of its performance, it can become very difficult to detect possible failures or adverse situations of equipment operation. This article describes a system designed for real-time monitoring and protection of transformers in overhead distribution lines via motorized circuit breakers, installed on the low voltage side. The remote control of the circuit breaker and the calculations of the hot spot temperature and the load of the transformer on the low voltage side will be performed by edge computing. The proposed solution aims to provide protection in the low voltage of the distribution grid and provides more information about the main asset of the utility in the distribution grid. The study is part of an innovation project by Enel Distribuição São Paulo, called “Urban Futurability”. This project is located in an area with a diversity of grid types, from underground grids with high load density to overhead grids of medium load density. The application of the proposed solution in this article will be carried out in part of the overhead grid of the project region, in the city of São Paulo, Brazil.

This paper describes a new methodology to identify conflicts between power flow control devices that can cause New-ton's method convergence problems. The proposed technique is based on applying the principal component analysis (PCA) to the control sensitivity matrix. This matrix directly relates the control mismatch functions and control variables. The results presented for small-scale and large-scale power systems were compared to the analysis of the eigenvalues of the power flow Jacobian matrix, indicating the proposed methodology effectiveness.

This paper analyzes and reports the vulnerabilities and threats of an experimental electric vehicle. The proposed approach employs an electric vehicle (EV) and communication instrumentation for collecting CAN bus messages. Data was collected through the Electronic Control Unit (ECU) and the battery management system (BMS) interface. Our focus is on decoding the CAN messages and injecting false messages to exploit EV cyber-physical performance by observing the electrical and mechanical data. We found out that the electric car powertrain can be degraded severely without the fault systems' activation. Due to different communication between the engine and the ECU, the overall efficiency and electrical power performance were compromised.

The high integration levels of non-dispatchable generation have necessitated more efficient formulations to cope with the increasing requirements for operating reserves and ramping capability. One aspect that has captured particular attention is the representation of opportunity costs derived from flexibility constraints, in order to propose efficient pricing rules for regulating reserves and flexible ramp products. In this work, a price rule for regulating reserves and flexible ramp products is proposed as a function of the opportunity cost and the available ramp capacity of the units. An example considering the IEEE RTS 24-Bus System is presented to show numerical results.
