摘要
微电网并网与孤岛运行模式之间的无缝切换控制策略是保证其安全稳定运行的重要因素。将新型主从控制策略及对等控制策略相结合,对微电网的并网模式向孤岛模式的切换过程进行控制。在DigSILENT/PowerFactory平台上构建由光伏电池和蓄电池相结合的微电网仿真模型,验证了所提出控制策略的正确性,保证了微电网有功、无功、电压及频率的稳定性。
The control strategy for micro-grid smooth switching between grid-connected and islanded modes is an important factor to ensure the safety and stable operation of micro-grid. The new type of master-slave control strategy and peer-to-peer control strategy were combined in this paper so as to control the operation mode transition between grid-connected operation mode and islanded operation mode of micro-grid. A micro-grid simulation model composed of photovoltaic cells and batteries was constructed on DigSILENT /Power Factory platform. The results show the control strategy for smooth switching between grid-connected and islanded operation is feasibility. The stabilities of the active and reactive power,the voltage,and the frequency are ensured.
