Grid-Enhancing Technologies: A Case Study on Ratepayer Impact
February 2022
**EnerNex contributed to this report**
The Department of Energy's Office of Electricity has released Grid-Enhancing Technologies: A Case Study on Ratepayer Impact, a report focused on the impacts of integrating Grid Enhancing Technologies (GETs) with existing transmission lines. GETs can defer or reduce the need for significant investment in new infrastructure projects and incre...
A Time-Domain Short Circuit Study for a VSC Based Battery Energy Storage System
Published via IEEE Xplore
Abstract
A phasor domain short circuit study for a battery energy storage system was performed per ANSI C37.010-2016. Results showed high short circuit asymmetrical currents. Two time-domain models were also built— simplified and detailed ——to compare the results with the phasor domain study. The results of both the simplified and the detailed...
WEBINAR | The Impact of Green Hydrogen on the Power System
Green hydrogen is playing a vital role in achieving deep decarbonization of the energy system. Experts from CESI, EnerNex, and encoord will explore green hydrogen's implications for the power sector, including:
Its role: Hydrogen strategy in the U.S. + Experiences from the E.U. (including CESI’s study of Green Hydrogen in ‘hard-to-abate’ sectors in Italy)
Possible schemes for integration o...
Cybersecurity Guide for Distributed Wind
August 2021
**EnerNex contributed to this report with Idaho National Laboratory (INL)**
Distributed wind sits at the intersection of grid-connected, off-grid, and behind-the-meter cyber-physical electric energy systems. The physical properties and communications requirements for distributed wind systems mean that there are unique cybersecurity considerations, but there is little to no existing guidance on b...

Resilience Framework for Electric Energy Delivery Systems
July 2021
EnerNex co-authored this report with Idaho National Laboratory (INL) introducing a framework to enable more thoughtful and deliberate consideration of resilience as it relates to electrical energy delivery systems (EEDS), with specific application to distributed wind systems.
The framework outlines three tiers of resilience which enable stakeholders to assess and improve their syste...
Global Experiences in Smart Metering - Tactical Loss Reduction in Developing Countries
Published via the IEEE Smart Grid Newsletter - June 2021
Written by Aaron F. Snyder, Vadim Zheglov, and Michele Pastore
In the developing world, there is a wave of smart grid technology implementations driven by the desire to reduce “commercial” losses (another term for “non-technical” losses, or those not directly related to the power system infrastructure). Qu...
