摘要
建立了包括光伏、钒电池(VRB)储能和能量管理系统的典型微电网结构,给出了基于VRB储能的微电网并网运行控制策略,分析了vRB建模及VRB储能系统在微电网并网运行过程中的控制作用。基于LCL滤波器的储能逆变器,采用三环控制策略,实现微电网瞬时功率调节的能力。最后,基于PSCAD/EMTDC仿真软件验证控制策略和参数选择的正确性,并在搭建的实验平台上进一步论证了上述控制策略的有效性。
The typically micro-grid structure, including photovoltaic, vanadium battery （VRB） energy storage and energy management systems are established.The network operation control strategies are given based on the VRB energy storage, the VRB modeling and micro-grid control action are analyzed during grid operation of VRB energy storage system.LCL fiherbased energy storage inverter control strategy using tricyclic control realize micro-grid instantaneous power adjustment capabilities.Finally, based on PSCAD/EMTDC simulation software,control strategies and the correct- ness of parameter selection are verified.Experimental results verify the effectiveness of the control strategy.
