新型电力系统动模平台设计及场站级振荡抑制验证OA

New power systems characterized by high penetration of renewable energy and extensive integration of power electronics face frequent wideband oscillations,reduced inertia support,and intensified dynamic coupling across multiple timescales.These challenges call for an experimental verification platform that combines physical fidelity with system scalability.To address the limited representation of physical details in purely simulation-based systems and the scale constraints of conventional dynamic simulation experiments,this paper proposes a dynamic simulation platform that integrates a physically scaled cluster with a simulation system.On the physical side,a scaled cluster comprising wind power,photovoltaic power,and energy storage converters,together with synchronous machines,is constructed based on similarity theory to reproduce both electromagnetic and electromechanical transient/dynamic characteristics.On the simulation side,a hundred-node power grid model is established to enable extension to complex operating scenarios.A high-precision digital-analog interface enables microsecond-level synchronized interaction between the two subsystems.By integrating full electromagnetic transient environment simulation,flexible operating scenario configuration,and multi-energy coordinated control,the platform establishes a full-chain experimental capability at the single-unit,station,and system levels,and supports the reproduction of multi-timescale dynamic behaviors and the verification of control strategies for sources,grids,loads,and storage.Experimental results of station-level oscillation suppression demonstrate that the proposed platform provides a reproducible experimental means for new power systems,supporting dynamic characteristic analysis,control strategy optimization,and equipment testing and verification.
