It represents a system-level and continuous balance between active power generation and load. To ensure ap propriate frequency quality\, disturbance rejection\, and power dispatch b etween units in the large system\, frequency controllers must be carefully tuned and sufficient power reserves must be maintained at all times. Even more\, such power reserves should be distributed in accordance with accep table cost compensations.\n\nThe new projections for the near-future Nordi c energy mix indicate substantial integration of inverter-based units and\ , consequently\, system operation under changing inverter shares and\, the refore\, inertia. An interesting challenge concerns fast frequency control and the role of invert-based units. There are efforts to optimize solutio ns between the use of associated frequency reserves and stability improvem ents. Furthermore\, with the more pronounced introduction of potentially i nverter-based units (e.g.\, batteries\, wind\, HVDC\, electric vehicles)\, other implications for system stability can arise. Specific concerns rela te to the synchronous generators' ability to synchronize in the presence o f large\, rapid power injections from inverter-based units. Additional cha llenges emerge as frequency control becomes more dispersed\, including app ropriate system-level and component modelling\, optimal control\, qualific ation requirements\, the choice of dimensioning disturbance\, and others t hat make this problem unique and relevant for the coming period.\n\nBio:\n Danilo Obradović is a researcher at RISE Research Institutes of Sweden AB in the Electric Power System unit\, focusing on power system stability\, control\, and modelling at various levels of integration of inverter-based resources.
