摘要
直流微电网稳定控制目标为直流母线电压的恒定,根据分布式微电源的工作特点,提出了基于通信网络的分布式微电源相互协商机制的稳定控制方法。此方法不依赖唯一的微电网中心控制单元的全局调控,是一种适用于不同分布式微电源间相互竞争与协作的自适应方法。在确保直流微电网稳定运行的前提下,具有运行方式自由性、控制方法灵活性的优点。仿真结果证明研究的自适应稳定控制方法,不仅能保证直流微电网的母线电压恒定,而且能实现各分布式微电源的既定运行方式和控制目标。
DC micro power grid stability control aims for DC bus voltage constancy.According to the operating features of distributed micro power,this paper proposes the stability control method based on communication network distributed micropower mutual consultation mechanism.This method,free from the dependence on the only global regulation of the micro grid center control unit,is an adaptive method suitable for the competition and cooperation between different distributed micropowers.This method can ensure the stable operation of DC microgrid,and it has the advantages of the flexibility of operation mode and control method.Simulation results prove that the adaptive control method can not only guarantee DC microgrid constant bus voltage,but also realize the set operation mode and control objectives of distributed micropower.
