FPGA-based simulation of grid-tied converters using frequency-dependent network equivalent
Bibliographic record
Abstract
This paper introduces a real-time simulation framework for grid-tied converters, implemented on field-programmable gate arrays (FPGAs). The framework incorporates a Frequency-Dependent Network Equivalent (FDNE) to reduce the original part of the circuit that is not directly under study into a frequency-dependent admittance model, enabling precise modeling of the power network’s frequency-dependent dynamics while streamlining the onboard simulation and modeling process. The proposed framework is implemented on the Alveo U280 FPGA, achieving sub-microsecond latencies, low resource utilization, and high computational fidelity across various data types, including single-, double-precision, and customized floating-point formats. The numerical test and validation were conducted using a high-voltage power network that includes detailed models of transmission lines, loads, and a Static Synchronous Compensator (STATCOM), etc. Simulation results show strong alignment with reference models developed in the EMTP, achieving faster-than-real-time performance. These findings demonstrate the effectiveness of the proposed solution in delivering high-speed, resource-efficient, and scalable real-time simulations, providing a promising approach for testing and validating advanced control strategies in modern power systems.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
