Systematic Design of Active Power Control Parameters for Multi-VSG Systems Based on Active Power Separation
Bibliographic record
Abstract
According to emerging guidelines, system operators are increasingly emphasizing three critical performance aspects from grid-forming (GFM) plants: active power-frequency (P-f) droop, low-frequency oscillation (LFO) damping, and active power setpoint tracking (APST) bandwidth. In GFM plants implemented by multiple virtual synchronous generators (VSGs), these performance aspects are dominated by VSGs active power control (APC) parameters, i.e., the inertia constant H and damping coefficient D. However, an APC parameter design with these performance aspects comprehensively considered remains unexplored, potentially leading to inappropriate P-f droop, underdamped LFOs, or excessive APST bandwidth. To address this issue, first, by separating the multi-VSG systems active power responses into a common part and a differential part, the analytical expressions for its LFO damping ratio and APST bandwidth are derived. Second, by aligning these performance aspects with the requirements outlined in representative GFM plant guidelines, a systematic APC parameter design method is proposed. This method explicitly formulates the feasible region for the APC parameters that ensures appropriate P-f droop, LFO damping, and APST bandwidth. Finally, real-time simulations and experiments are conducted in various multi-VSG systems to validate the theoretical analysis and the proposed APC parameter design method.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
