SUMMARY:Webinar: Measures to Address Stability Issues in Fingrid
DESCRIPTION:Download Presentation \nView Webinar Recording \n\nFeatured Speaker: Antti Harjula\, Head of Power System Engineering\, Fingrid \nAntti Harjula\nAbout the Webinar: Fingrid has been using extensive series compensation\, power system stabilizers (PSS) and power oscillation damping (POD) controls to increase system transfer capability since the 1990s. PODs have been used in HVDC links\, SVCs and wind power plants. In recent years\, the massive integration of inverter-based renewables\, especially wind power\, has worsened the situation with classical stability issues as well as introduced new forms of stability issues. Resonance stability issues have been addressed with the implementation of damping requirements and sub-synchronous oscillations (SSO) protection requirements for inverter-based resources (IBR). Converter driven stability issues have been tackled with re-tuning of wind power plant controllers and unit level controls\, control mode changes and IBR output curtailment during specific outages and with new investments in the grid assets\, such as synchronous condenser (under construction) and STATCOMs with grid forming controls (in design stage). Also\, grid forming capability requirements have been introduced on battery energy systems (BESS). This year Fingrid is planning to introduce additional requirements for stabilizing behavior of wind and solar power plants and looking towards piloting grid forming controls on wind power plants. This presentation will give an overview on technical solutions to improve stability in the Finnish transmission system. \nAbout the Speaker: Antti Harjula is head of Power system engineering at Finnish transmission system operator Fingrid. The unit is responsible for power system modelling\, power system technical performance analysis and developing the requirements and capabilities for future system. Antti has been with Fingrid over 15 years and has been working on different system analysis\, power system planning and modelling topics all these years. Antti has special interest in integration of renewable energy and has also been visiting researcher in Imperial College London where he analyzed the impact of wind power control tuning on system stability. \nModerator: Julia Matevosyan\, Chief Engineer\, ESIG \nRegistration Cost: FREE \nQ&A Session: We will be using the slido platform for Q&A. Please submit your questions and follow-along during the event at this link.

SUMMARY:G-PST/ESIG Webinar Series: Advances in the Use of Probabilistic Resource Adequacy Methods
DESCRIPTION:Download Presentation \nView Webinar Recording \nDownload Q&A \n\nFeatured Speaker: Aidan Tuohy\, Director\, Transmission Operations and Planning\, EPRI \nAidan Tuohy\nAbout the Webinar: Ensuring resource adequacy – a measure of whether the current\, or projected\, resource mix is sufficient to meet capacity and energy needs for a particular grid– is crucial for ensuring a reliable energy transition. Probabilistic approaches have traditionally been used to assess resource adequacy\, but in light of the changing nature of the resource mix\, increased demand participation and the recent implications of extreme events\, there is a need to revisit how resource adequacy is assessed. As recent events have shown\, existing methods\, models and tools for assessing resource adequacy do not always accurately portray risk and identify the potential for shortfalls\, particularly during periods of extreme system stress such as cold weather. In this webcast\, we will hear about the recently completed EPRI Resource Adequacy for a Decarbonized Future Initiative (www.epri.com/resource-adequacy). This project\, which ran from mid-2021 to end of 2023\, addressed a number of issues and challenges related to resource adequacy (RA). As resources such as wind/PV\, batteries\, demand flexibility and hybrids\, as well as future resources such as hydrogen and long duration storage\, enter the system\, models and tools need to be able to include their characteristics compared to traditional resources. EPRI’s project built on other ongoing industry work\, including the ESIG Resource Adequacy Task Force\, and focused on a few main workstreams. A Process workstream focused on the metrics\, criteria and scenarios used in RA studies. Here\, recommendations on metrics to be assessed and the insights they provide were described\, while methods for identifying short and long term scenarios to be studied were developed. A Models and Data workstream investigated existing and emerging approaches to model supply and demand side resources\, as well as data required to characterize these resources. Recommended approaches were then provided\, with different levels of detail based on how important a given resource type is to the system being studied. A Software Tools workstream surveyed existing and emerging tools for RA assessment\, with the result being a greater understanding of current capabilities of commercial and research grade software\, as well as new approaches and gaps. Underlying all of these workstreams\, Case Studies of 6 different North American systems were used to support the material developed and identify how risk is evolving in each area. Here\, the final deliverables\, all of which will be public\, will be described\, with a deep dive on a number of them. The session will conclude with a discussion on next steps for ensuring RA studies leverage the latest approaches\, and future work in the area. \nAbout the Speaker: Aidan Tuohy is the Director of EPRI’s Transmission Operations and Planning R&D Group\, managing a portfolio of near and long-term research\, thought leadership and applications\, with a focus on supporting the reliable\, resilient and affordable transition to a clean electricity system. His team of over 70 individuals have deep subject matter expertise spanning long term planning\, operations planning\, real time operations\, system protection and market design and operations. \nHe received a Bachelor of Engineering degree in electrical/electronic engineering from University College Cork\, Ireland in 2005. He completed his doctoral degree at the University College Dublin Electricity Research Centre in 2009\, on the topic of operating and planning issues in carbon-constrained power systems. During his studies\, he spent time in both Risoe-DTU (Denmark) and the National Renewable Energy Laboratory. \nModerator: Charlie Smith\, Executive Director\, ESIG \nRegistration Cost: FREE \nQ&A Session: We will be using the slido platform for Q&A.

SUMMARY:Webinar: DER Transmission Study Overview and Findings
DESCRIPTION:Download Presentation \nView Webinar Recording \nDownload Q&A \n\nFeatured Speakers: Keegan Moyer\, Principal\, Energy Strategies and John Muhs\, Senior Consultant\, Energy Strategies \nAbout the Webinar: This study investigates the relationship between distributed generation (DG) and transmission infrastructure planning\, focusing on the Western United States. Our findings confirm that DG can\, at moderate levels\, reduce the need for new transmission investments. However\, as DG penetration increases\, there’s a shift: more transmission capacity and energy storage become necessary. The study’s findings highlight the need for a balanced approach considering resource diversity on both sides of the meter in future resource and transmission planning efforts. \nAbout the Speakers: Keegan Moyer joined Energy Strategies in 2014 and directs the firm’s transmission and market analyses. His project teams combine grid simulation tools\, complex industry datasets\, and economic analyses to help clients identify and evaluate generation and transmission investments\, market strategies\, and energy policies. Keegan is also responsible for the firm’s client services related to interconnections and transmission service. In addition\, he has provided expert witness services on transmission- and interconnection-related matters in multiple states. Geographically\, he has worked for clients in the Western\, Eastern\, and Texas Interconnections. Some of Keegan’s more recent projects include serving as the WestConnect Order 1000 Region Planning Consultant project manager\, benefit-cost analyses for major transmission projects\, leading open solicitation processes for merchant transmission\, and supporting renewable energy developers on interconnection\, curtailment\, and transmission basis risk analyses. \nJohn W. Muhs joined Energy Strategies in September 2019 and provides analytical support for the Transmission Planning and Energy Markets area of the firm. John collaborates on projects relating to renewable infrastructure siting\, transmission planning\, and energy market economics. Using a variety of programming tools\, John compiles\, interprets\, and visualizes energy and economic data for production cost and long-term resource planning models. John seeks to automate repeatable processes for the firm by developing custom-tailored scripts for data collection and analysis. John also assists in developing business intelligence dashboards and other interactive tools for Energy Strategies’ clients. \nModerator: Debbie Lew\, Associate Director\, ESIG \nRegistration Cost: FREE \nQ&A Session: We will be using the slido platform for Q&A.
