An adaptive normalized droop control strategy for the interlinking converter of hybrid microgrid has been proposed in this paper. The standard can realize bidirectional power coordination between subgrids. However, transmission accuracy is low, and subgrid bus voltage varies from rated value. avoids unnecessary flow so as to achieve accurate effective deviation compensation. In study, low AC/DC examined. It be deduced mathematics that increase coefficient improve accuracy. variation added operation criteria IC, which reflect load state, prevent frequent action when IC close working condition. state equation system obtained by small signal modeling, upper limit a stability constraint. Based on preceding analysis, method designed This ensures receiving kept state. Corresponding simulations based MATLAB/Simulink experimental results hardware-in-the-loop platform have illustrated.
