摘　　要：在电能路由器储能优化的研究中,为了缓解大规模屋顶光伏直接并网给配电网带来的负面影响,研究了交直流混合微网架构的电能路由器在包含屋顶光伏和混合储能单元的家庭能量管理系统中的应用。利用Matlab/Simulink平台搭建了相应的仿真模型,制定了集中式分层能量管理策略,提出了一种混合储能-可切除负荷的控制策略,并进行了孤岛运行模式下的仿真研究。结果表明,提出的电能路由器控制策略能够在光伏出力和负荷突变的情况下维持瞬时功率平衡,保证交直流母线电压稳定,并且能够提高混合储能单元的运行效率及工作寿命。In order to mitigate the negative effects caused by direct grid connection of large scale rooftop PV to the distribution network,the application of hybrid AC / DC framework based electric power router to the home area network with rooftop PV and hybrid energy storage unit is investigated. The corresponding simulation model is built on the Matlab / Simulink platform. A centralized multi-level energy management strategy is developed and the control strategy based on hybrid energy storage unit and load shifting is proposed. Simulation of the presented system in islanded operation mode is carried out,which shows that the electric power router based control strategy has enabled such effects to be achieved： maintenance of the instantaneous power balance in case of sporadic change of PV output or load profile,assurance of voltage stability of the AC and DC power lines,as well as improvement of operational efficiency and service lifetime of the hybrid energy storage unit.
