【摘要】：从孤岛运行时微电网的无功电压特性着手,分析了微电网无功电压的控制措施,提出了在孤岛模式下基于具有自趋优分布式特点的多智能体系统(MAS)的微电网无功电压控制策略。利用分布式能源增发、投切电容和投切负荷相结合的控制方法,解决了孤岛模式下的微电网电压控制问题。最后,通过仿真验证,证明了该方法可以有效地调节控制系统的母线电压及微源的无功输出功率,维持系统的稳定运行。
[Abstract]:Based on the characteristics of reactive power and voltage of microgrid in islanding operation, the reactive power and voltage control measures of microgrid are analyzed, and the reactive voltage control strategy of micro-grid based on multi-agent system (MAS) with self-optimizing and distributed characteristics in isolated island mode is proposed. The problem of microgrid voltage control in isolated island mode is solved by using the control method of distributed energy supply, switching capacitor and load switching. Finally, the simulation results show that the method can effectively adjust the bus voltage and reactive power output of the micro-source, and maintain the stable operation of the system.
