| Abstract: |
| The research of distribution network with distributed photovoltaic generation system and its equivalent model has become an important research means of distribution network stability. The control schemes, electromagnetic transient characteristics and the mechanical properties of distributed photovoltaic generation system, synthetic load with rotary motor and constant impedance load, and nonlinear load are analyzed and modelled, and the models are simplified into equivalent Thevenin-Norton models with unified form. The consistency of hardware equivalence and control equivalence of power electronic device is discussed. The outputs of equivalent model and detailed model of an improved IEEE 13-bus distribution network are compared on MATLAB/Simulink simulation platform, and results show that the outputs of the two models are fitting well with good accuracy. |
