The issue of dc current injection at low voltage autonomous or interconnected grids as a result of photovoltaic (PV) systems integration is thoroughly discussed in this paper. This paper focuses on the sinusoidal pulsewidth modulation inverter with a low-frequency step-up transformer, as this was widely used in the past at PV grid connected applications, while nowadays, it is a favorable solution in standalone multisource residential applications. This paper highlights the fact that dc current injection is possible even at the presence of a low-frequency transformer. In addition, the impact of the dc current flow on the transformer efficiency is studied, and appropriate design considerations are extracted-thus limiting the dc current component in an efficient manner. The proposed design considerations are validated through experimental results accomplished on laboratory and commercial PV power conversion products.

This paper proposes to use time domain reflectometry (TDR) to detect water trees in underground residential distribution (URD) cables. Water trees are very dangerous to underground cables. They can grow for years without any change on the performance of the cable, and then can cause the cable to fault unexpectedly. Therefore, a method to detect water trees in URD cables is proposed in this paper. The method implements an optimal pulse generator placement algorithm on a distribution feeder for performing TDR. It can determine the exact location of a water tree in a cable, and it does not rely on the length of the cable or the type of cable used. The method can also detect multiple water trees on the same cable, and can be installed on existing systems, since it does not require data of the healthy system. It is a periodic monitoring system where pulses are sent throughout the year. The proposed method has been verified using multiple case studies on a real distribution feeder. Using TDR, optimal pulse generator placement, and subtraction of cables' measured signal in time domain with similar measured signals a critical distribution feeder's health has been monitored successfully.

This paper presents the results of three control strategies of managed energy services with home energy management system (HEMS)-integrated devices. The HEMS controls and monitors three types of managed devices: 1) heating; 2) task-specific; and 3) energy storage devices. Three approaches are proposed for the rolling optimization by the HEMS, namely, mixed integer linear programming (MILP), continuous relaxation (CR), and fuzzy logic controller (FLC). The CR approach is identified to reduce the computational complexity of the MILP by changing the MILP into an LP solution. Three types of FLC control approaches are proposed, namely, heat-related FLC, task-related FLC, and FLC for the battery. Each control strategy is evaluated against cost optimization, computational resource, and practical implementation. The findings in this paper show that all three algorithmic control strategies successfully perform cost optimization, even with inaccurate forecasting information.

The energy management system (EMS) at utility control centers collects real-time measurements to monitor current grid conditions. The EMS is also a suite of analytics that synthesizes these measurements to provide the grid operator with information to identify current problems and potential future problems. With evolving grid influences, such as growth of variable renewable generation resources, distributed generation, microgrids, demand response (DR), and customer engagement programs, managing the grid is becoming more challenging. Concurrently, however, there are nascent new technologies and advances in grid management schemes that will improve the ability to manage the future grid operations. These technologies include new subsecond synchrophasor measurements and analytics, advances in highperformance computing, visualization platforms, digital relays, cloud computing, and so on. Advances in grid management schemes include adding more intelligence at the substation and distribution systems, as well as microgrids and wide-area monitoring systems. One key initiative is to develop a predict-and-mitigate paradigm enabling anticipatory vision and timely decisions to mitigate potential problems before they spread to the rest of the grid. The word “proactive”means “to act now in anticipation of future problems.”Proactive grid management opportunities and solutions are described in this paper.

Analyses have shown that electric vehicle (EV) loads may considerably affect the secondary service voltage quality. One of the ways to mitigate voltage drop concerns is to use a time-of-use (TOU) pricing scheme. A TOU pricing scheme utilizes the off-peak generation for EV charging, thus deferring any immediate grid upgrade and improving the grid sustainability. This paper evaluates various aspects of EV charging under a TOU schedule, with off-peak rates starting at hours ranging from 8 P.M. to 3 A.M. The study is conducted using an actual residential distribution circuit. A best practical time to begin the off-peak rates is determined so that the effects of EV charging on the secondary service voltages are minimized while ensuring that EVs are fully charged by 7 A.M., thus maximizing both grid and customer benefits. The analysis suggests that the best time to begin off-peak rates is between 11 P.M. and 12 A.M. Furthermore, the analysis also suggests that setting up TOU off-peak rates at the latter half of the peak load demand, for example, at 8 P.M., is detrimental to the distribution circuit voltage quality. The result indicates that the existing utility TOU scheme may exacerbate voltage drop problems due to EV load charging.

Historically, the inspection and maintenance of high-voltage power lines have been performed by linemen using various traditional means. In recent years, the use of robots appeared as a new and complementary method of performing such tasks, as several initiatives have been explored around the world. Among them is the teleoperated robotic platform called LineScout Technology, developed by Hydro-Québec, which has the capacity to clear most obstacles found on the grid. Since its 2006 introduction in the operations, it is considered by many utilities as the pioneer project in the domain. This paper’s purpose is to present the mobile platform design and its main mechatronics subsystems to support a comprehensive description of the main functions and application modules it offers. This includes sensors and a compact modular arm equipped with tools to repair cables and broken conductor strands. This system has now been used on many occasions to assess the condition of power line infrastructure and some results are presented. Finally, future developments and potential technologies roadmap are briefly discussed.

This paper presents an optimal RC ladder-type equivalent circuit for the representation of the soil for dynamic thermal rating of underground cable installations. This is useful and necessary for their optimal and accurate real-time operation. The model stems from a nonuniform discretization of the soil into layers. The resistive and capacitive circuit elements are computed from the dimensions and physical parameters of the layers. The model is perfectly compatible with the International Electrotechnical Commission thermal–electric analog circuits for cables. The optimum model order is determined, for fast and slow thermal transients, from a comprehensive parametric study. It is shown that an exponential distribution of the soil layers leads to accurate results with differences of less than 0.5 °C with respect to transient finite-element simulations. An optimal model with only five layers that delivers accurate results for all practical installations and for all time scenarios is presented. The model of this paper is a simple-to-use and accurate tool to design and analyze transient operation of underground cables. It represents a relevant improvement to the available operation and monitoring tools. For illustration purposes, a step-by-step model construction example is given. The model has been validated against numerous dynamic finite-element simulations.

Utilities are often asked to investigate and determine the cause of elevated voltage in the urban environment. By understanding proper measurement techniques, how to interpret readings, and the possible sources of the voltage, investigators can reach speedy and accurate conclusions and eliminate unwanted voltage.

On 1 September 2009, as part of a new node-based market implementation, the Electric Reliability Council of Texas transitioned from its then-prevalent data modeling processes to a new network model management system (NMMS) for model data management. This change represented the culmination of nearly four and a half years of planning and development. The NMMS provided several improvements over the then-current data maintenance processes. This paper describes some of the existing issues facing the power industry in the area of power system model data management and explains how solutions to these issues were addressed conceptually in the development of and incorporated into the final design of the NMMS. Further, this paper explains how these concepts of design and usability are now gaining wider recognition and acceptance from the industry.

The photovoltaic (PV) generation is increasingly popular nowadays, while typical loads require more high-power quality. Basically, one PV generator supplying to nonlinear loads is desired to be integrated with a function as an active power filter (APF). In this paper, a three-phase three-wire system, including a detailed PV generator, dc/dc boost converter to extract maximum radiation power using maximum power point tracking, and dc/ac voltage source converter to act as an APF, is presented. The instantaneous power theory is applied to design the PV-APF controller, which shows reliable performances. The MATLAB/SimpowerSystems tool has proved that the combined system can simultaneously inject maximum power from a PV unit and compensate the harmonic current drawn by nonlinear loads.
