孤岛模式下微电网自趋优分布式无功电压控制策略

摘要

Starting from the characteristics of microgrid reactive power and voltage in the island operation mode,control measures of the microgrid reactive power and voltage are analyzed.A microgrid reactive power and voltage control strategy based on a multi-agent system (MAS) characterized by being self-approach-optimal and distributed in the island mode is proposed.By using the control method of combining the issuance of distributed energy,capacitor switching and load switching, microgrid voltage control problems in the island mode are solved.Finally,simulation verification shows that the method can effectively regulate the bus voltage of the control system and reactive power output of micro-sources,while maintaining stable operation of the system.%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(MA S )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。
