As distributed energy resources (DERs) are creating unprecedented challenges for the electric grid, electric utilities must adapt to a new energy landscape paradigm. This article discusses technologies needed and available.
The magnetic field exposure analysis tool uses balanced & unbalanced load-flow currents and angles to determine the location of the worst-case magnetic field exposure due to conductors in underground raceways.
This case study presented by Vu Duc Quang, Deputy Director of Training, Research and Development Center, at PECC2 in Vietnam, explains how peaking electricity consumption in North - and high penetration of renewable energy sources in South Vietnam pose great pressure on the grid. PECC2 utilized ETAP to model Vietnam's power system, calculate and analyze power systems scenarios, identify the optimal location and install capacity of Battery Energy Storage Systems, based on the criteria of reducing/avoiding overload of the power grid and peak shaving. This presentation will demonstrate how BESS solutions with capacity and location calculated with ETAP have shown a clear effect in reducing the power system’s overload.
Learn how engineers use ETAP Harmonic Analysis software to simulate harmonic current and voltage sources, identify harmonic problems, reduce nuisance trips, design, and test filters, and report harmonic voltage and current distortion limit violations on balanced or unbalanced systems. Additionally, for transmission and distribution system operators, Harmonic Grid Code automates harmonic analysis for detailed power quality assessment reporting demonstrating the generation facility is designed to comply with applicable harmonic limits. Study reports include worst-case incremental and total harmonic distortion, frequency-dependent Thevenin Equivalent at PCC, and color-coded impedance loci charts.
Renewable energy systems continue to be one of the fastest growing segments of the energy industry. This paper focuses on the understanding of how photovoltaic (PV) technology behaves under dc arc conditions.
An integrated Electrical Digital Twin driven design software & control hardware for microgrids, power plants & nanogrids to embrace the integration of renewable energy while facilitating safe, reliable & efficient power system operations.
A brief overview on how to shorten the project duration for power system modeling and studies from months to weeks, utilizing ETAP Network Project Management (NetPM™), a platform for collaborative engineering.
Reduce risk, improve safety & enforce compliance based on ENA NENS 09-2014.
Calculate optimal and alternative cable sizes for phase & ground conductors.
Automated Arc Flash Energy Evaluation - When performing protection and coordination studies it is difficult to anticipate potential arc flash coordination issues due to the differences between the arc and bolted fault currents. Arc Flash Auto solution automatically evaluates arc-flash incident energy and equipment arc flash damage points to quickly resolve these conflicts limiting the number of scenarios required or even removing the need for an isolated arc flash study.
