摘要

本文提出了一种自适应控制技术，可在提供惯性特性的同时提高成网变换器的电能质量和频率稳定性。该方法采用虚拟同步发电机模型，模拟了传统同步电机的运行，减轻了高惯性值引起的不稳定性。提出的自适应惯性策略根据频率约束的变化率动态调整仿真惯性。仿真和实验结果表明，该方法提高了频率稳定性，降低了各种条件下的功率振荡，是提高电网成形变流器运行的可行方案。

Adaptive Inertia Controller for Grid-Forming Converters

This paper presents an adaptive control technique for grid-forming converters to enhance power quality and frequency stability while providing inertial behavior. Using the virtual synchronous generator model, the approach emulates traditional synchronous machines operation but mitigates instability caused by high inertia values. The proposed adaptive inertia strategy dynamically adjusts the emulated inertia based on rate of change of frequency constraints. Simulation and experimental results demonstrate improved frequency stability and reduced power oscillations across various conditions, making this method a viable solution for enhancing grid forming converter operation.
