基于DIgSILENT软件的微电网动态仿真

基于DIgSILENT软件,介绍了分布式电源逆变器控制模块的仿真模型,并对由恒功率控制的微源和V/f控制的储能装置组成的微电网进行了联网转孤岛运行的仿真,结果表明该系统可以稳定工作于联网和孤岛模式,并能实现二者切换时的平滑过渡,提高了微电网供电可靠性。;The simulation model of the inverter for distributed generation in the DIgSILENT software is introduced,and some simulation is taken on the micro-grid consisting of constant power control generation and V/f control energy storage element.The results show that the system can work in stable grid connected and islanding operation mode,and can achieve smooth transition between these two modes,enhancing the reliability of the power supply of micro-grid
