Abstract: For the study of dynamic performance of microgrid operation, to establish reasonable battery dynamic model is very meaningful. Introduction was made to a kind of three-order dynamic model based on lead-acid batteries and the corresponding simulation model was established in SIMULINK of MATLAB to analyze the dynamic characteristics of the model in the process of charging and discharging. On the basis of P/Q decoupling control principle, the battery energy storage system was connected to the grid and would be applied to stabilize the power fluctuations of distributed power. Simulation results verify the validity of the model and control strategy.
Key words: microgrid; battery modeling; P/Q decoupling control; power fluctuation
