Abstract
Considering the problem that the active power output from storage modules cannot be reasonably distributed in a multi-storage AC microgrid,this paper proposes an improved droop control strategy based on the state of charge of the energy storage module,on the basis of stabilizing the frequency of the microgrid.Firstly,by constructing a power-exponential function model of the energy storage state of charge and droop coefficient,this control strategy enables each energy storage module to adaptively adjust the output active power according to its own state of charge,which ultimately achieves the state of charge equilibrium.Secondly,small signal analysis is used to analyze the stability of the strategy.Finally,the effectiveness of the proposed strategy is verified by Matlab/Simulink simulations and semi-physical experiments.关键词
