摘要
为研究含风力发电、太阳能光伏发电和储能系统三种类型微源组成的微电网的运行特性,在MATALB软件平台上,建立了基于主从控制的风光储微电网联合仿真模型.以蓄电池储能系统为主控电源,在微电网并网运行时,所有微源都采用P/Q控制;微电网离网运行时,蓄电池储能系统采用V/f控制,支撑微电网频率和电压.然后对微电网并网运行、离网运行及并离网切换过程进行仿真.仿真结果表明:微电网在并网、离网运行模式下能安全、可靠运行,在运行模式切换过程时能平滑过渡.
In order to study the operating performance of micro-grid composed of three types of micro sources,including wind power generation,solar photovoltaic power generation and energy storage system,a joint simulation model of wind power/photovoltaic/storage micro-grid based on master-slave control is established on MATLB software platform.The battery energy storage system is the main control power supply.When the micro-grid is connected to the grid,all micro sources are controlled by P/Q;when the micro-grid is off grid,the battery energy storage system is controlled by V/f to support the frequency and voltage of the micro-grid.Then the process of grid connected operation,off grid operation and parallel off grid switching is simulated.The simulation results show that the micro-grid can operate safely and reliably in the grid connected and off grid operation modes,and can transition smoothly in the operation mode switching process.
