Abstract: Due to different line impedances in microgrids, there are problems such as unreasonable distribution of harmonic current and negative sequence current, and many controller updates. A coordinated control method of reactive power and harmonic power in microgrids based on event triggered consistency algorithm is proposed. Firstly, the microgrid hierarchical coordinated control architecture is established, through the dynamic adjustment of adaptive virtual impedance, the equivalent impedance between the distributed generations(DGs) tends to be consistent, and accurate reactive power and harmonic power distribution is achieved. Then, under the communication network with time delay, a distributed reactive power and harmonic power controller based on event trigger consistency is designed. The state information is exchanged at the trigger time, and the actual value is replaced by the estimated value at other times. Lyapunov method is used to prove the stability of the proposed method and avoid Zeno phenomenon. Finally, the effectiveness of the proposed power sharing control method is verified by experiments.
