Th e crucial hypothesis on which such a model is defined is that the frequenc y required to define all phasors and system parameters is constant and equ al to its nominal value. This model is appropriate as long as only synchro nous machines regulate the system frequency through standard primary and s econdary frequency regulators. In recent years\, however\, an increasing n umber of devices other than synchronous machines are expected to provide f requency regulation. These include\, among others\, distributed energy res ources such as wind and solar. There is thus\, from a modeling point of vi ew\, the need to define with accuracy the local frequency at every bus of the network.\n\nThe lectures presents the definition of “complex frequen cy” and poses the basis of a set of equations that link this new quantit y with the active and reactive power injections at network buses. These re lationships allow defining how device models and their controllers impact the frequency at their point of connection. This is particularly relevant in the context of low-inertia systems where the frequency support must be provided by power electronic converters and devices other than conventiona l synchronous power plants. The lecture will show how the concept of compl ex frequency can be utilized both as a metric to quantify the dynamic perf ormance of frequency and voltage controllers and as a powerful tool to des ign new efficient control strategies. All concepts are illustrated through examples based on IEEE benchmark systems.\n\nRoom: Zaal Wind\, Bldg: Ener gyVille 1\, Thor Park\, Genk\, Limburg\, Belgium\, Virtual: https://events .vtools.ieee.org/m/375745 LOCATION:Room: Zaal Wind\, Bldg: EnergyVille 1\, Thor Park\, Genk\, Limburg \, Belgium\, Virtual: https://events.vtools.ieee.org/m/375745 ORGANIZER:pes.sb.leuven@gmail.com SEQUENCE:11 SUMMARY:DLP Lecture from Federico Milano ‘Complex Frequency and Simple Co ntrol in Low Inertia Systems’ URL;VALUE=URI:https://events.vtools.ieee.org/m/375745 X-ALT-DESC:Description: <br /><p><span style="font-weight: 400\;">The conve ntional power system model for transient stability analysis assumes of qua si- steady-state phasors for voltages and currents.
