Dynamic phasor-based hybrid simulation for multi-inverter grid-connected system
摘要
Abstract
To realize the efficient transient simulation of a grid-connected power generation system based on multiple inverters,this paper proposes a hybrid simulation method integrating the models of electromagnetic transient and dynamic phasors.Based on a demonstration of the concepts and properties of dynamic phasors,the models of single-phase and three-phase inverters described by dynamic phasors are established first.Considering the numerical compatibility problem between dynamic phasors and instantaneous values,an interface scheme between dynamic phasors and instantaneous values is designed,and the efficiency and precision differences of various transformation methods are compared in detail.Finally,by utilizing MATLAB/Simulink,a hybrid simulation platform of a multi-inverter grid-connected system is built,and the efficiency and accuracy of the hybrid simulation are validated via comparison with the full electromagnetic transient simulation.关键词
