Modelling and Implementation of Multi?source Isolated Microgrid Using Virtual Synchronous Generator Technology
摘要
Abstract
To improve the living standards,economical efficiency and environmental protection of isolated islands, remote areas and other areas with weak electric power facilities construction,a multi-source independent microgrid system is studied,including diesel generators,photovoltaic power generation system,wind power generation system and energy storage unit. Meanwhile,in order to realize the voltage and frequency stability control of AC bus of multi-source microgrid,the virtual synchronous generator technology is introduced into the energy storage unit,and the charge and discharge control of the energy storage battery are simulated as the control behavior characteristics of synchronous motors,so as to provide damping and inertia support for the microgrid. The operation mode and control principle of each energy subsystem are expounded and analyzed. The algorithm principle of virtual synchronous generator and the control method of energy storage unit are given. Then,the working modes of the microgrid system under different environmental conditions are analyzed,and the multi-source microgrid system simulation model is built based on MATLAB/Simulink. The simulation results show that the microgrid system can run stably under different working modes and the energy storage unit using the virtual synchronous generator technology can provide good voltage and frequency support for the microgrid system. Finally,experiments verify the supporting function of energy storage unit on the voltage and frequency of the microgrid system.关键词
