This paper presents the results of a life cycle assessment (LCA) of two variants of a 145kV high voltage circuit breaker (HVCB) gas insulated switchgear (GIS) substation: (i) SF6-based SP-3, and (ii) SF6-free Eco, which uses the eco-friendly fluoronitriles-based Novec 4710 synthetic gas mixture. The ReCiPe2016 midpoint-oriented calculation methodology is used, which provides life cycle impact assessment results in terms of 18 environmental impact indicators, that are then grouped into four life cycle stages; production, transportation, use and end-of-life. First, an LCA of both variants is performed. Next, a comparative LCA of the SF6-based and SF6-free HVCB GIS is conducted, followed by interpretation of the results considering the most influential parameters. The results indicate that adopting the SF6-free Eco variant has a significant positive impact on global warming potential, a key climate change indicator. Finally, the characteristic features of the LCA are summarized along with recommendations for future strategy and improvement.

Flexibility in inverter-based loads could be used to support the converter-dominated power grid by offering a rapid, autonomous, and adjustable power reserve during system transients to help maintain system stability. Based on technical potential, ancillary service (AS) value, and implementation costs, this study illustrates the cost-benefit analysis of grid-supportive loads (GSLs) for the supply of fast frequency response (FFR). The net benefit for each GSL is demonstrated using a case study and relevant data sources. The findings suggest that implementation costs for enabling GSL features are low compared to the value that grid operators get from the acquisition of responsive reserve services. The authors believe that, given the rising popularity of renewable energy sources, GSLs can be a useful tool for grid stability in low-inertia systems.

This paper proposes an operational scheduling model of distributed energy resources (DERs) and PV smart inverters with Volt-VAr controller using an accurate AC optimal power flow (ACOPF) in an unbalanced distribution network. A mathematical mixed-integer model of local Volt-VAr droop controller of the distributed mixed-phase PV smart inverters is proposed based on the IEEE 1547-2018 standard and is incorporated in the unbalanced ACOPF, which enables effective utilization of the Volt-VAr controllers to not only alleviate voltage issues locally but also at the feeder level. The proposed model is tested on two actual snapshots of a distribution feeder in Arizona. Also, the proposed operational scheduling method considering the Volt-VAr droop controller of PV smart inverters is compared with a recent work in scheduling of the PV smart inverters. The results illustrate that the PV smart inverters dispatches obtained by the proposed model can be practically implemented by local controller of inverters.

A fast heuristic dispatch algorithm for series modular power flow control (M-PFC) devices is proposed to effectively control the power flow in transmission lines and consequently alleviate overloads in normal operation or contingency scenarios. Solving the nominal M-PFC dispatch problems is a computationally expensive non-linear program. Our fast heuristic dispatch algorithm leverages line outage distribution factors (LODFs) to model the impact of the M-PFC on the power flow change in the transmission lines, resulting in an iterative linear program that can be solved very quickly. Our proposed dispatch algorithm is assessed on three different test cases, IEEE 24 bus, IEEE 39 bus, and a real large-scale test case with 1723 buses. The numerical results support the effectiveness of the approach in terms of overload relief and its efficiency in terms of computation time. The proposed dispatch algorithm is applicable in both real-time operation and offline planning studies.

with the rise of distributed energy resources (DERs), and electrification of customer loads, the electric grid is experiencing a period of rapid change. As utilities prepare for this transition, it is critical to protect and enhance the resilience of infrastructure serving vulnerable communities. With the combination of electrification, localized clean energy assets, two-way communication and control of grid-connected devices, SEED pilot projects create foundational utility experience around creating a modernized grid. This paper provides the results of a series of studies performed for a senior housing campus located within the DLC service territory in Pittsburgh, Pennsylvania.

In this paper, the potential for time series classifiers to identify faults and their location in a DC Microgrid is explored. Two different classification algorithms are considered. First, a minimally random convolutional kernel transformation (MINIROCKET) is applied on the time series fault data. The transformed data is used to train a regularized linear classifier with stochastic gradient descent (SDG). Second, a continuous wavelet transform (CWT) is applied on the fault data and a convolutional neural network (CNN) is trained to learn the characteristic patterns in the CWT coefficients of the transformed data. The data used for training and testing the models are acquired from multiple fault simulations on a 750 VDC Microgrid modeled in PSCAD/EMTDC. The results from both classification algorithms are presented and compared. For an accurate classification of the fault location, the MINIROCKET and SGD Classifier model needed signals/features from several measurement nodes in the system. The CWT and CNN based model accurately identified the fault location with signals from a single measurement node in the system. By performing a self-learning monitoring and decision making analysis, protection relays equipped with time series classification algorithms can quickly detect the location of faults and isolate them to improve the protection operations on DC Microgrids.

Event analysis is a staple of system protection, yet it is easily hindered by limited and lacking data. This is especially relevant at points of utility interconnection as interagency cooperation is necessary for robust fault analysis. Even so, protection engineers are expected to reach reasonable conclusions about unexpected operations which can be particularly difficult when power system phenomena like parallel line resonance is involved. In this particular case, a permanent phase-to-ground fault demonstrated a correlation between a shunt reactor and the capacitive coupling between two transmission lines in the same right of way that interconnect multiple utilities and electrical systems. As is demonstrated, the utility proposed theory of the mutual coupling inducing zero sequence current on the de-energized line was inaccurate as a diagram of the zero sequence network reveals a missing zero sequence voltage source. Instead, the phase-to-ground fault formed a zero sequence resonant network between the shunt reactor inductance and the de-energized line capacitive coupling. This circuit was then excited by circulating zero sequence current and sustained by zero sequence voltage induced from the adjacent, energized, parallel line. Analysis of this resonant circuit shows the potential for extremely high induced voltage magnitudes which are governed by the topography and geometry of both parallel lines and location of the phase-to-ground fault.

The electricity grid includes intelligent devices that support monitoring, automation and control functions and gather data. Some data is used operationally and some is used for planning, engineering, management, accounting or other purposes. Individual devices may support data that is useful for multiple purposes. Traditional grid device implementations only permit devices to provide data to a restricted range of applications.The modern, intelligent grid benefits from the integration of data from all sources, made available to all applications. This paper discusses some of the benefits, issues and considerations to enable such a comprehensive integration of grid device data from all sources for all uses.

In North American, most residential electrical meters are of the form 2S type. While the neutral conductor from the split-phase transformer to the customer’s service panel is routed through the meter socket, the meter does not have a connection to the neutral conductor. Line 1 and line 2 voltage magnitudes are nominally equal when referenced to the neutral. Conditions arise that the neutral connection becomes compromised, in which case the line 1 and line 2 voltages become unbalance, creating potentially hazardous conditions. This paper describe an algorithm in a form 2S smart meter can use to detect a faulted neutral connection by observing changes in the currents seen by the meter even though it does not have a direct connection to the neutral reference point. Results of laboratory experiments show that it is possible to detect faulted neutral conditions in a typical household in less than a day.

Conservation Voltage Reduction (CVR) enables electric distribution utilities to achieve a significant reduction in energy and peak demand, and without impacting customers through load shedding or major equipment investments. With the deployment of Dynamic VAr Controllers (DVCs) at the secondary side of distribution transformers, the voltage will be regulated tightly at local and feeder-wide level. In addition, when DVCs provide voltage regulation and visibility at the secondary side, there is more room for voltage reduction and thereby the benefits of CVR get enhanced. Based on a pilot project and field testing at Commonwealth Edison Company (ComEd) in Chicago, Illinois, this paper measures and shows the benefits of DVCs in raising voltage at limiting nodes by 0.88% – 2.04%. Further, a regression-based calculation method is presented to estimate the energy savings. The results show 1.23% extra energy savings exclusively provided by DVCs deployment.
