A Generic Reduced-order Modeling Hierarchy for Power-electronic Interfaced Generators With the Quasi-constant-power Feature
摘要
Abstract
Reduced-order modeling and transient stability simulation are crucial for studying renewable energy generations' integration into power systems through power-electronic interfaces.The battery energy storage system (BESS) was selected to model power-electronic interfaced generators with quasi-constant-power feature caused by its electromechanical decoupling essence.Thus,a generic differential algebraic equation (DAE) modeling hierarchy was proposed,which is adaptive to different accuracy and complexity requirements,based on multiple-time-scale analysis and singular-perturbation equivalence theory.Performances of the proposed models were validated in simulation with various extemal disturbances and internal configurations of BESS.The models are able to reveal and quantify transient stability essence caused by power-electronic interface's quasi-constant-power feature.关键词
