Coordination control of DC microgrid considering energy storage system optimization
摘要
Abstract
A phase-shifting controlled dual half bridge converter based coordination control strategy is proposed for autonomous DC microgrid.With bus voltage stability and supply and demand balance of active power as primary targets,the strategy changes the phase angle in terms of the bus voltage fluctuation to control the power of storage energy batteries,which ensures the stable and reliable operation of the autonomous DC microgrid.The use of the dual half bridge converter can achieve the electrical isolation of the batteries,and the phase shift control can improve the step-up ratio of the converter so as to enhance the safety of the energy storage system.The autonomous DC microgrid model is established and analyzed by virtue of Matlab/PSIM joint simulation platform.Simulation results show that the coordination control strategy can stabilize the output power of the energy storage batteries.The small voltage fluctuation and the fast response speed when disturbances happen demonstrate that the method can effectively improve the system reliability.关键词
