Abstract

En 中文

This paper proposes a compositional grid code framework that guarantees power system stability and dynamic performance simultaneously. By reformulating device-grid interactions based on passivity theory, we derive compositional stability indices compatible with heterogeneous dynamics. Then, the proposed grid codes decompose system-level stability certificates into quantitative constraints upon individual devices while accommodating standard dynamic specifications. Compared with existing approaches, this method overcomes the previous limitations in closed-loop stability assurance and facilitates the plug-and-play integration of heterogeneous dynamic devices.
