This paper investigates how to perform online system identification employing synchrophasor data. Two approaches to identifying a reduced-order model are presented: a purely data-driven approach, and an approach that integrates online data-driven dynamic system identification with firstprinciple offline selective modal analysis. With prior knowledge of the frequency range interesting to power system operators, it is shown that the second approach recovers the key modes of the original system and produces a much reduced-order model of grid-level dynamics. Even with the presence of uncertainty about the actual modes of interest, an automatic tuning scheme is devised to adaptively adjust the frequency range to improve system identification. Numerical examples with synthetic synchrophasor data demonstrate the efficacy of the proposed identification approach.

The contemporary distribution network is metamorphosing into a weak, stressed and vulnerable network. The strategy adopted to ameliorate this potential menace is shifting electricity supply away from today's centralized service model towards a more dispersed structure. Sequel to the non-centralized operational paradigm is the penetration of V2G at the nodes of the electric distribution network. A V2G facility has the potential to provide economic incentives in an electric distribution network. In this paper, economic models are developed to quantify the amount of economic incentives that can be derived from the penetration of V2G into the power distribution network. Different V2G operational strategies are considered, and then observing how this operational changes impact economic incentive due to V2G penetration in the system. Three novel economic models were developed: (1) economic model to quantify the prospects of V2G when used for ancillary services in power systems, (2) economic evaluation due to released energy in the distribution network when V2G penetrates the system, and (3) the impact of location, V2G capacity and feeder loading on annual economic incentives. The results show that V2G promises significant economic incentives. The results obtained in this study emphasize the importance of proper system studies that considers different scenarios of V2G operational strategies.

With rapid increase in deployment of advanced metering infrastructure, the amount of the data collected increases dramatically. Incorporation of such voluminous data requires wide-ranging transformation of the existing metering infrastructure. However, as the number of smart meters increases to more than hundreds of thousands, it would become increasingly clear that the state-of-the-art centralized information processing architecture will no longer be sustainable under such big data explosion. In this short communication letter, we propose an implantable data storage-and-processing solution for improving the existing smart meter infrastructure. The practicality of the proposed solution is validated on a proof-of-concept testbed.

The recent changes on the electrical power systems make the role of distributed generation more important. Employing distributed generation in demand side allows the consumers to have active participation in the electricity markets. This paper implements the real-time simulation of a local microgrid that consists of two subsystems: home area network and neighborhood area network. In this system, the home area network is the electrical grid of a house and the neighborhood area network is the low voltage electrical distribution grid of the neighborhood. The main contribution of this paper is to assess scenarios for energy transactions between these two areas using real resources. In the case studies, several real profiles have been employed for simulating the consumption and generation of this local microgrid.

Combined economic and emission dispatch (CEED) is a key challenge for the system operator in the open access regime and is used to operate generators that produce energy in a power plant with least costs as well as least emission simultaneously. Stability issues must, therefore, be considered during CEED. This paper presents a multi-objective formulation of CEED in a power system, with the competing objective functions of minimizing fuel cost and emission. Non-dominated Sorting Multi Objective Opposition based Gravitational Search Algorithm (NSMOOGSA) is used as an optimization tool. Fuzzy decision maker is used to extract the best compromise non-dominated solution. The proposed method has been tested on the IEEE 30-bus system and results are compared with those of the other reported in the recent literature. The quality of the results establishes the efficacy of the proposed approach in solving different CEED problem.

Low voltage (LV) wiring and distribution transformers are an important part of the system delivering electricity to the customer, but information about the performance, and even about the lengths and impedances, of service-level components has been limited in the past. Now that increased pressures are being put on the grid by distributed generation and new loads, and the system is being held to closer tolerances through programs like conservation voltage reduction (CVR), it is becoming more important to understand the voltage drops at the LV service level. However, these voltage drops are rarely measured and reported on in the literature, particularly for US systems. This paper discusses three methods for measuring for LV secondary drop, using newly available measurements of customer voltage by advanced metering infrastructure (AMI) alongside other data. Based on AMI measurments and other data from three US utilities, it was found that while most secondary drops are within the ranges typically cited by utilities, there are a few spots with larger voltage drops that could be a problem given future CVR programs or the installation of additional load or PV.

To be designed for a self-monitoring protection and control system that would minimize wiring and troubleshooting, a 345kV Substation for a US Transmission Company for had to interoperate with multiple vendors' relays. An IEC 61850 based solution was chosen to facilitate multi-vendor compatibility. Interestingly, IEC 61850 interoperability turned out to be a major challenge as different vendors IEC 61850 software settings and implementations differ significantly. The project reinforces the importance of considering the initial cost of deployment but also the costs of potential upgrade paths as technology continues to improve.

Different solutions for non-conventional instrument transformers have been developed in the last decade and are now available for HV gas insulated switchgear. Manufacturers have integrated Rogowski coil into high voltage GIS for current measurement and capacitive principle for voltage measurement. These concepts were realized in different types of products such as RC voltage dividers, external Rogowski coils in electronic current transformers (eCT), etc. Special electronic units for preprocessing and merging of sampled measured values have been developed to convert the outputs (low power or optical) to the standard IEC 61850-9-2- for each NCIT technology. This ensures the compatibility as well as interoperability of any protection device with the appropriate digital interface. Installed NCIT technology will provide many benefits for utilities and manufacturers, including reduction of SF6 insulation gas (environmental benefit), simplified wiring, and efficiency in manufacturing and engineering. Additional technical benefits include seamless-unified measurement and higher accuracy. The paper describes NCIT technologies, integration in high voltage gas insulated switchgear, benefits and qualification processes with customer/utilities, which lead to reliably and accepted products.

This paper focuses on testing the dynamic behavior of single-phase air conditioner motors on distribution power networks. The primary goal is to study the phenomenon of delayed voltage recovery by applying multiple instances of a custom-built single-phase induction motor model on a given distribution feeder. This model was developed in an Electromagnetic Transients Program (EMTP) simulation environment. The motors were subjected to voltage disturbances seen in feeders experiencing the fault-induced delayed voltage recovery (FIDVR) phenomenon. To study the FIDVR phenomenon, a range of voltage depressions were simulated for predetermined system conditions. This paper describes a point-on-wave model development and simulation study that supports a broader investigation of the effect of air conditioning and similar loads on the recovery of electric utility voltage after faults.

In electrical systems, co-axial cables have come to be widely used (for example, transmission systems, building inner wirings and so on). A surge current entering into the cables might cause severe damage to them. Therefore it is necessary to investigate surge phenomena of the cable from the surge propagation point of view. An FDTD method (Finite Difference Time Domain) has recently been applied to analyze this kind of surge phenomena. Accordingly, we have adopted a VSTL rev. (Virtual Surge Test Lab. rev.) which is a surge analysis program developed by CRIEPI (Central Research Institute of Electric Power Industry) in Japan to carry out surge simulation. In this paper, we first discuss the comparison results of surge experiment results by means of a co-axial cable (Type RG58 A/U) and of simulations by means of VSTL rev. Secondly, we illustrate surge phenomena that have arisen on a co-axial cable which is connected with a transmission line through a cable junction. Finally, we discuss these results.
