变流器跟踪性能-抗扰性能-经济代价间的矛盾三角关系
Trade-off Triangle of Tracking Performance,Anti-interference Performance,and Economic Cost of Grid-connected Converters
摘要
Abstract
Enhancing the power tracking capability and voltage/frequency active support of converters is critical for stabilizing modern power systems,while their synergistic optimization remains unclear.This study investigates the inherent coupling mechanisms among tracking performance,anti-interference performance and economic costs through open-loop zero analysis of AC grids.A Jacobian transfer function matrix model is developed for grid-connected converters,with two novel evaluation methods proposed:a tracking performance metric based on closed-loop bandwidth and an anti-interference assessment method utilizing sensitivity function values.The research further analyzes the influence mechanisms of control architectures and operational scenarios on dynamic characteristics,revealing a trade-off triangle among tracking performance,anti-interference performance and economic costs.The study finds that individual converters constrained by three-dimensional performance boundaries require coordinated control of multiple grid-following(GFL)/grid-forming(GFM)converters to achieve global optimization.Simulation validations confirm the theoretical analysis,thus establishing a design paradigm for enhancing converter comprehensive performance in complex power systems.关键词
