Abstract
The distributed energy storage system in DC microgrid is of great significance in stabilizing the randomness and vol-atility of distributed generation units.Aiming at the problem that in the traditional droop control,the line impedance difference of each energy storage unit leads to the DC bus voltage deviation and the inability to achieve accurate power distribution between each energy storage unit,an improved droop control is proposed.The communication layer uses a consensus algorithm to calculate the re-quired average data for communication between energy storage units.In the droop control layer,a power function exponential control method based on the state of charge of the energy storage unit is proposed,which adaptively adjusts the droop coefficient,increases the virtual voltage drop equalization control,and improves the power distribution difference caused by the line impedance.The droop control layer outputs the control signal to control the bidirectional DC/DC converter of the energy storage system.The model of DC microgrid energy storage system is built in Matlab/Simulink,and the different operation conditions are analyzed.The simula-tion results show that compared with the traditional control method,the proposed control strategy can realize the power balance dis-tribution of energy storage unit with different state of charge(SOC)and the stable operation of bus voltage.关键词
