| 摘 要： | 在DIgSILENT仿真软件上搭建了包含风力发电、光伏发电、燃气发电机等微电源以及蓄电池储能系统的微电网仿真模型。研究了该风光储气微电网在并网启动过程、并网转孤网过程、孤网运行时光伏出力变化及负荷变化等暂态过程中的稳定性问题。其中包括并网转孤网的过程中,储能的控制方式从PQ转换为VF,实现微电网运行模式的转换;孤网运行时,储能迅速响应微电网内功率的波动,实现放电与充电模式的切换,保持微电网的稳定运行。

| Abstract: | A micro-grid simulation model is built based on DIgSILENT simulation software,which is composed of wind power,photovoltaic(PV) power,gas generator and storage battery.Then the research focuses on the stability of the transient processes of the micro-grid,including grid-connected start-up,connected-isolated operation mode switch,PV output and load change during islanded running.To be specific,during the connected-isolated operation mode switch,the control mode of storage battery converts from PQ to VF;during islanded running,storage battery can respond rapidly to the micro-grid power fluctuation,achieving mode conversion between discharge and charge,so that the micro-grid can maintain stable operation. |
