新能源智能微网中的三相固态变压器整流级均压均功率新方法
A novel DC-link voltages and power balancing control method for cascaded three-phase solid state transformer of new energy smart microgrid
摘要
Abstract
With the widely application of renewable energy.how to manage them becomes a problem.FREEDM system center put forward the energy of the Internet.In this system the SST is called energy router,which can realize real-time control of voltage and current,the bidirectional power flow,strong compatibility for distributed energy.It contains rectifier stage,dual active bridge (DAB) transformation stage and inverter.But this structure also has brought some problems.such as,voltage and power imbalance.A new and simple control scheme is proposed to reconstructs the vector modulation wave.On the basis of traditional double closed loop control and DC voltage balance control,by introducing the modulation wave error component to reconstructs the initial modulation wave to distribute the active power as required and the reactive power equally among H-bridges.Its correctness and effectiveness are tested and verified by simulation with MATLAB/Simulink.关键词
