摘要:
针对微电网中采用逆变器下垂控制的分布式电源时难以实现无功出力合理分配,存在无功环流等安全运行隐患的问题,该文提出一种基于有限时间一致性控制的孤岛微电网分布式协调无功均分策略。该方法在无集中控制器的架构下对无功出力进行均分控制,减少系统无功环流,提高电压质量。相较于传统的一致性策略,所提出的无功均分策略的收敛速度更快,能实现收敛时间及速度的优化,且可适应微电网各种扰动。通过在PSCAD/EMTDC中建立孤岛微电网仿真模型,在多种场景下验证了分布式无功均分策略的有效性和适应性。
Abstract:
In order to solve the problem that the distributed generator using the inverter droop control in the microgrid is difficult to realize the reasonable distribution of reactive power,and there are hidden problems in the safe operation of reactive power circulation,a distributed reactive power sharing strategy for islanded microgrid based on the finite time consistent control is proposed here. The reactive power output is equalized under the framework of no centralized controller,which can reduce the reactive circulating current of the system and improve the voltage quality. Compared with the traditional consistency strategy,the proposed reactive power sharing strategy has faster convergence speed,can optimize the convergence time and speed,and adapt to various disturbances in microgrid. In order to verify the reactive power sharing effect of the control strategy,a simulation model of the islanded microgrid is established in PSCAD/EMTDC. The effectiveness and adaptability of the distributed reactive power sharing strategy are verified in many scenarios.
