Webinar: Measures to Address Stability Issues in Fingrid
Download Presentation View Webinar Recording Featured Speaker: Antti Harjula, Head of Power System Engineering, Fingrid Antti Harjula About 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…

Download Presentation View Webinar Recording Download Q&A Featured Speaker: Aidan Tuohy, Director, Transmission Operations and Planning, EPRI Aidan Tuohy About 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…

Download Presentation View Webinar Recording Download Q&A Featured Speakers: Keegan Moyer, Principal, Energy Strategies and John Muhs, Senior Consultant, Energy Strategies About 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…
