英文摘要	Microgrids (MGs) arc deemed as one of the main building blocks of the smart grids. It is important to enhance the power quality in the islanded MGs. However, the power quality can be deteriorated under unbalanced and non-linear loads. In this paper, a Distributed Secondary Control. (DSC) method, for voltage unbalance compensation in islanded MGs is proposed. Also, based on the communication technology and hierarchical control theory, a new networked hierarchical control, scheme is presented for the DSC of MGs. In the control, structure, each unit, is independently controlled and the entire system of controllers is connected by a communication network. Compared to the centralized secondary control, scheme, it, makes the MG systems reduce the requirements of communication links bandwidth, toward standardization and. be easy to expand. The proposed approach is not, only able to compensate voltage unbalance at, the Point, of Common Coupling (PCC), but, also ensures reactive power sharing accurate. The design procedure of the control, system is discussed in detail. Finally, simulation experimental, results are presented to show the effectiveness of the proposed method in the compensation of voltage unbalance. © 2015.
