Reflections on 10 years of ESIG Forecasting Workshops
Read More: Reflections on 10 years of ESIG Forecasting WorkshopsThe 10th anniversary edition of the ESIG forecasting workshop returned to the scene of the inaugural workshop in St Paul, MN on June 19-21, 2018. To many of those that attended the first workshop on Feb. 21-22, 2008, it was apparent that there have been significant but in some cases subtle changes over the past…

Implementation of Inertia Monitoring in ERCOT – What’s It All About?
Read More: Implementation of Inertia Monitoring in ERCOT – What’s It All About?Synchronous inertia characterizes the ability of a power system to oppose changes in electric frequency after large and sudden changes in active power production or consumption. The level of inertia present in a system at any time is dependent on the amount of kinetic energy stored in rotating masses of synchronously-interconnected machines: both generators and…

New Report Shows that Solar, Wind, and Storage Can Competitively Power a Majority of Minnesota’s Electric Needs
Read More: New Report Shows that Solar, Wind, and Storage Can Competitively Power a Majority of Minnesota’s Electric NeedsMinnesota can produce 10 percent of its electricity from solar by 2025 and 70 percent from solar and wind by 2050 at generation costs comparable to natural gas. Building additional solar and wind capacity coupled with energy curtailment is less expensive than building long-term or seasonal storage. Thursday, November 15, 2018, Saint Paul, MN: Minnesota…

Ignoring Electrical Frequency in an All Converter Power System
Read More: Ignoring Electrical Frequency in an All Converter Power SystemSince the early 1900s, with the proliferation of alternating current rotating generators and development and setup of electric grids, the electrical frequency in the network has nobly served as the pulse of the electric power system. The electrical frequency connects the speed of rotation of the generators to the power consumed by the loads. Thus,…

Reliability, Resilience, and Fuel Security: Product Definition in Wholesale Electricity Markets
Read More: Reliability, Resilience, and Fuel Security: Product Definition in Wholesale Electricity MarketsPresident Trump directed Energy Secretary Rick Perry to prepare “immediate steps” to halt the loss of “fuel-secure power facilities.” Secretary Perry sent a letter to FERC saying the “resiliency of the electric grid is threatened by the premature retirements of these fuel-secure traditional baseload resources” and provided a proposed rule to better compensate them. While…

Measures for Managing South Australian Power System Accounting for Lessons Learned from the Recent Blackout Event
Read More: Measures for Managing South Australian Power System Accounting for Lessons Learned from the Recent Blackout EventThe South Australian (SA) power system exhibits one of the highest penetrations of asynchronous generation worldwide, with only one AC interconnector to a neighbouring power system. The installed asynchronous generation amounts to approximately 2 GW including two transmission connected battery energy storage systems (100 MW and 30 MW respectively). This is supplemented by approximately 900…
