Webinar: Measures to Address Stability Issues in Fingrid
February 15 @ 3:00 pm - 4:00 pm EST
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 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.
About 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.
