The compactness of Gas-Insulated Substations (GIS) allows their installation in building even at extra-high voltage levels, like 800 k V. This is one of the key options to consider when physical security is of primary concern. Substation can be totally blended within the landscape and gives little room to ill intentions. These integrations coupled with the development of digital technologies also reduce significantly the requirement for access to the equipment which improves the security aspects of the assets. This paper is giving various examples illustrating these aspects.

The traditional way of issuing a transmission and distribution construction package is multiple copies of bulky binders and large plan and profile drawings in fiberboard tubes. Some of this information is also required to be transmitted to various agencies such as environmental, land acquisition and Construction personnel. Typical data include location identifier, pole height and class, foundation details, framing and wire stringing information. Ampirical has upgraded the transmittal of this design data to a more accurate and more efficient interface which utilizes currently available technologies. All design location information can be visualized in a geographical computer software platform such as Google Earth. The most up to date construction statuses are represented with icons and colors. Construction issues can be promptly identified by reviewing the status map and site photos that are attached to each structure location. All critical information could be quickly retrieved with or without an internet connection on a tablet at the office, construction site, and maintenance and/or storm damage locations.

The growing adoption of Distributed Energy Resources (DERs) such as rooftop solar, onsite energy storage and electric vehicles requires power utilities to support increasing grid interconnections, and higher system reliability standards. This electrical distribution grid of the near future requires advanced distribution automation applications to provide foundational grid capabilities. These capabilities include advance Fault Detection Isolation and Restoration (FLISR) functionality. For correct and reliable grid operation, these advance distribution automation applications should consider various load restoration scenarios and significant amount of dynamically changing distributed energy recourses. These factors increase the complexity of the algorithms used by the applications and require reliable communication systems to exchange all critical information between the automation controllers in the field. To support the future distribution grid, authors believe for fast, reliable, and efficient operations such automation systems should have intelligence at the edge of the network. To achieve this goal, authors are developing a modern distribution automation control system with advanced protection and automation logic capabilities utilizing distributed intelligence architecture. As an added benefit of the distributed intelligence approach, this new automation system has a minimal impact on SCE's existing distribution, substation protection, and grid management systems. Resulting in a drop into place solution, which is interoperable with existing systems. The chosen communication system, however, ultimately defines the reliability of the entire system and its operating speed. For approximately 25 years, Southern California Edison has utilized a mesh connected radio system, called Netcom, for supervisory control and data acquisition (SCADA), which now contains over fifty thousand nodes. This system works with sub-gigahertz frequency, thus having very good propagation and reliability. However, the radio terminals operate with serial interface utilizing the DNP3 protocol that does not support a large-scale peer-to-peer data exchange. The distributed intelligence application logic can efficiently work if multiple devices can quickly exchange fault information to make operational decisions. To achieve this, status and critical fault information from any field controller must be available to the rest of the system. In order to leverage SCE's Netcom system and perform peer-to-peer data exchange over the DNP protocol, authors developed the new DNP Router concept. The DNP Router allows a DNP based communication system to mimic a publisher-subscriber communications model by polling individual controllers in the field and sending (a.k.a. publishing) the acquired information back to assigned (a.k.a. subscribed) system components via commands. However, the legacy Netcom communication system has a number of limitations which includes packet size and bandwidth ca

This paper presents a method to determine optimal energy and power capacity of distributed Energy Storage Systems (ESS) in behind-the-meter applications to maximize local Photovoltaic (PV) utilization or minimize Demand Charge (DC) cost. The problem is solved as a multiobjective optimization model to obtain a set of Pareto optimal solutions for each scenario in each month. An approach is then presented to map the monthly Pareto fronts into a single yearly Pareto front. A cost benefit analysis has also been carried out to show the compromise between PV utilization, DC cost, and ESS cost.

This paper provides information concerning the monitoring and diagnosis of hot metal gases, with special attention given to the detection of hydrogen. Though hydrogen is a superior indicator of incipient faults due to its generation through all temperature zones over 150°C, the detection and analysis of hydrogen levels can be quite erratic. The theories set forth in this paper, offer an examination of hydrogen's physical reactions within the main tank of a transformer which can lead to this erratic and often misleading behavior.

This paper describes impedance measurements conducted by American Electric Power (AEP) on a new 345 kV transmission project near Fort Wayne, Indiana, featuring an innovative high-capacity/high-efficiency compact line design trademarked BOLD™ (Breakthrough Overhead Line Design). Measurements were performed in cooperation with OMICRON Electronics Corporation (OMICRON), a provider of testing and diagnostic solutions, which developed a novel method and instrumentation employed in this application. Results revealed close agreement (1–3% difference) between the measured and analytically obtained positive-sequence impedances for the measured line. Differences in zero-sequence impedances were much larger (about 20%), reflecting the use of a generic assumption for earth resistivity in computing transmission line electrical characteristics. Accurate knowledge of line impedances can enhance the reliability of protection settings, thus minimizing the risk of relay misoperations. Also, it can advance the quality of power system models used in planning, engineering and operating studies, as mandated by NERC under Reliability Standard MOD-032-1.

Overhead Transmission and Distribution lines are designed to convey electrical power across vast regions. Key to their long-term design and safe operation is the ampacity rating that dictates the upper operational temperature the line is designed to handle. Incorrect line ampacity rating modelling parameters can result in the conductor operating at a much higher temperature than predicted and introduce a Temperature Risk condition where electrical line clearance is severely violated, as well as causing physical and thermal degradation to both the conductor and associated hardware. Using an Engineered Surface Coating enables the use of prescribed values for emissivity and absorptivity throughout the life of the conductor, working to mitigate the possibility of a Temperature Risk condition. This paper provides example calculations and field results that show the effectiveness of an Engineered Surface Coating material in use in North America.

In this paper, a proportional-integral (PI) controller is designed for the DC-DC Buck converter to regulate its output voltage in presence of load current and line voltage disturbances. The parameter of PI controller is tuned based on the stability boundary locus approach. A step-wise procedure is discussed for tuning the PI parameters to satisfy the minimum phase margin requirements. For precise control, the nonidealities of the Buck converter have been included in its mathematical model. State-space averaging technique is used to obtain the duty cycle to output voltage transfer function of the non-ideal Buck converter. Finally, the performance of the proposed controller is validated on an experimental prototype.

One of the potential problems with increasing renewable generation in microgrid is frequency regulation. Due to high variability of renewable generation resources, the imbalance between load and generation may lead to instability of the system. Since the microgrid can not compensate the power imbalance from the main grid, demand response in general and battery storage system specifically, can contribute in frequency regulation of microgrid. Conventional generator regulates the frequency with load frequency control (LFC) loop. Batteries connected to inverters can also contribute in regulating the frequency with the embedded frequency-watt control curve in inverter. In this paper, distributed battery storage systems are utilized to correct a given frequency deviation in the microgrid. The battery contribution is analyzed in centralized and decentralized environments. The optimal value of droop of distributed batteries are obtained and the small signal stability of the system is investigated.

Dynamic wireless power transfer (DWPT) for electric vehicle (EV) charging is an emerging technology driven by the need to reduce current battery capacity limitations. DWPT has the potential to increase driving range as well as reduce charging time while managing battery related factors including weight, form factor and prohibitive costs. A novel integrated DWPT model for EV charging in Matlab/Simulink was developed to investigate three inductive power transfer (IPT) charging coil configurations: long loop, sectional loop and spaced loop at low, medium and high EV densities (number of EVs per km) in the Caribbean twin island Republic of Trinidad and Tobago. The Highway Fuel Economy Test (HWFET) driving cycle was applied. Simulations of regenerative braking and DWPT using three charging configurations at three levels of EV densities without regenerative braking were compared. The results revealed that the sectional loop and long loop charging configurations offered the greatest benefits; the sectional loop allowed for a 280.1% and 13.1% increase in driving range and a 68.75% and 9.5% reduction in battery capacity for the low and medium EV density cases respectively while the long loop configuration allowed for a 43.2% increase in driving range and 27.5% reduction in battery capacity for the high EV density case.
