An important aspect of all power processing equipment is common-mode current generation. Common-mode current leads to electromagnetic noise and potential equipment malfunction. Common-mode inductors are often used to reduce common-mode current. However, their effectiveness is limited by their capacitance. In this paper, common-mode capacitance models of two related classes of common mode inductors are set forth. These models include an improved method of calculating the layer-to-layer capacitance. Means of reducing capacitance by use of multiple inductors is discussed. The methodology for calculating capacitance is experimentally validated using several common mode inductors. Finally, the use of the model in a multi-objective optimization-based common mode inductor design algorithm is demonstrated.

This paper describes a detailed nonlinear electromagnetic model for predicting current in transformers commonly used to supply electrical power in rural arc welding applications. Current-limiting in these welders during quenched arcs is achieved using a gap-less core design, resulting in high-magnetizing impedance but also a significant degree of magnetic saturation. To accurately predict transformer currents during arc welding, the proposed model includes nonlinear magnetization effects. Parameter identification of the magnetic properties of the transformer core is performed using a population-based search algorithm using open-circuit transformer measurements. The model is validated using measurements on an experimental transformer during live arc weld testing.

Numerical optimization-based solution to directional overcurrent relay (DOCR) coordination problem has been a widely addressed research problem in the recent past. Many linear (LP), nonlinear (NLP), mixed integer nonlinear (MINLP), mixed integer linear (MILP), and quadratically constrained quadratic programming (QCQP)-based formulations have been presented in the past literature. This paper proposes a new MILP-based formulation using disjunctive inequalities. The nonlinear DOCR protection coordination model is formulated as MILP by linearizing the bilinear terms existing in the original formulation. One of the variables in each bilinear term is discretized over its interval into a fixed number of steps. After assigning binary variables to each discrete interval, the resulting bilinear terms with binary variables are written in terms of disjunctive inequalities. The results have shown that the proposed MILP formulation fetch better optimal solutions compared with past MILP and MINLP formulations. The MILP problem is programmed in GAMS package with CPLEX solver and tested on standard 3 bus, 9 bus, 15 bus, and 30 bus systems and results are found to be satisfactory.

This paper presents an investigation on the performance of voltage regulators (VRs) in mitigating overvoltage problems caused by distributed energy resources (DERs) in medium-voltage (MV) distribution systems. The control method of VRs is found to be a crucial factor. Studies reveal that even advanced control modes of commercial VRs cannot be relied upon as effective solutions to manage every scenario. The main problems associated with local control methods are identified. A supplementary voltage control scheme is proposed to enhance the capability of VRs as a solution option. The proposed scheme addresses the problems due to local control methods with a minimal investment. The studies are accompanied by several simulations on IEEE 123 nodes system as well as an actual feeder facing such overvoltage problems. Merits of the proposed supplementary control scheme are also demonstrated through simulation results.

Electromagnetic transient (EMT) simulation of power electronics conducted on the CPU slows down as the system scales up. Thus, the massively parallelism of the graphics processing unit (GPU) is utilized to expedite the simulation of the multi-terminal DC (MTDC) grid, where detailed models of the semiconductor switches are adopted to provide comprehensive device-level information. As the large number of nodes leads to an inefficient solution of the DC grid, three levels of circuit partitioning are applied, i.e., the transmission line-based natural separation of converter stations, splitting of the apparatus inside the station, and the coupled voltage-current sources for fine-grained partitioning. Components of similar attributes are written as one CUDA C function and computed in massive parallelism by means of single-instruction multi-threading. The GPU’s potential as a new EMT simulation platform for the analysis of large-scale MTDC grids is demonstrated by a remarkable speedup of up to 270 times for the Greater CIGRÉ DC grid with time-steps of 50 ns and $1~mu text{s}$ for device-level and system-level simulation over the CPU implementation. Finally, the accuracy of GPU simulation is validated by the commercial tools SaberRD and PSCAD/EMTDC.

This paper introduces a framework for comprehensive testing and evaluation of the phasor measurement units (PMUs) and synchrophasor systems under normal power system operating conditions, as well as during disturbances such as faults. The evaluation is suggested to be accomplished using three different testing approaches, namely, type testing, application testing, and end-to-end testing, for each of which, systematic characterization of the hardware and software modules is presented in detail. Through the proposed approach of PMU testing in a controlled environment and detailed analysis of different estimation techniques used in PMU algorithms, one can gain insights on which estimation technique is most accurate for a certain end-use application. This hypothesis has been validated through series of realistic test scenarios on a 23-bus system running on an Opal Real Time simulator using the hardware-in-the-loop interface. In addition, the impact of synchrophasor estimation errors and their propagation from the PMU toward the end-use applications has been quantified for a fault location algorithm that uses only PMU measurements.
本文介绍了在电力系统正常运行以及故障等干扰情况下对相量测量单元(pmu)和同步相量系统进行综合测试和评估的框架。建议使用三种不同的测试方法来完成评估，即类型测试、应用测试和端到端测试，并详细介绍了每种测试方法的硬件和软件模块的系统特征。通过提出的在受控环境中进行PMU测试的方法，以及对PMU算法中使用的不同估计技术的详细分析，人们可以深入了解哪种估计技术对于某个最终用途应用是最准确的。这一假设已经通过在Opal Real Time模拟器上运行的23总线系统上使用硬件在环接口的一系列实际测试场景得到验证。此外，对于仅使用PMU测量值的故障定位算法，同步量估计误差的影响及其从PMU到最终应用程序的传播已经被量化。

This paper discusses the effects of Hurricane Maria on Puerto Rico’s electric grid. Arguably, the most significant effect of Hurricane Maria on Puerto Rico was the electric power outage that initially affected the entire island and lasted more than ten months. Although the damage to the conventional electric power generation infrastructure was relatively minor, both the transmission and distribution portions of the grid suffered much worse damage than that observed during other hurricanes that affected the U.S. in the past decade. This extensive damage added to logistical limitations and the island orography were important factors that contributed to an extremely slow restoration process leading to a very low resilience for the island’s power grid. This paper describes all these aspects in detail and supports the explanation of the hurricane effects with photographic evidence collected during a damage assessment conducted in the early December 2017 when about half of the electricity customers were still without service. This paper concludes by exploring some lessons from these observations including potential options to increase resilience, such as the use of microgrids.

The offshore wind resource is very large in many coastal regions, over 80,000 MW capacity in the region studied here. However, the resource cannot be utilized unless distant offshore wind generation can be effectively collected and brought to shore. Based on extensive oceanographic, environmental, and shipping data, a realistic wind energy deployment layout is designed with 160 wind power plants each 500 MW. The power collection and transmission infrastructure required to bring this power to shore and connect it to the electricity grid is designed and analyzed. Three types of connection to shore are compared; high voltage AC to the nearest onshore point of interconnection (POI), high voltage DC with voltage-source converter (HVDC-VSC) to the nearest onshore POI, and connecting to an offshore HVDC backbone running parallel to shore that interconnects multiple wind power plants and multiple POIs ashore. The electrical transmission losses are estimated step by step from the wind turbines to the POI. The results show that such a large system can be built with existing technology in near-load resources, and that losses in the HVDC-VSC systems are approximately 1%–2% lower than that in the AC system for a distance about 120 km from shore.

In this paper, a compositional power flow (ComPF) is devised for networked microgrids to take into account power sharing and voltage regulation between microgrids while preserving data privacy of each microgrid. The main contributions of the ComPF include: 1) devising an advanced-droop-control-based power flow to incorporate distributed energy resources and load droops within microgrids and 2) establishing an adaptive-secondary-control-based compositional power flow scheme to account for power sharing and voltage regulation between microgrids. As an inherently distributed method, the ComPF supports plug-and-play of microgrids and preserves customer privacy.
