摘　　要：针对传统的直流微网结构中分布电源变流器多采用功率均分的控制策略而不能实现输出功率任意分配的情况,采用了基于MPPT算法与负载电流前馈的智能型升压控制器,实现了太阳能光伏电池板在直流微网系统中输出功率的任意调节。仿真和实验结果表明,与传统的分布电源功率均等输出的控制方法相比,该控制方法可以由分布电源输出任意功率。Aiming at the power output allocation problem that the power sharing control strategy in the traditional DC microgrid which using the distributed power converters cannot make outer power allocation arbitrarily,an intelligent BOOST circuit based on MPPT algorithm and load current feed-forward method is used to realize the arbitrary regulation of the output power of the PV panels in the DC microgrid system.The simulation and experimental results show that the proposed method can realize arbitrary power output from the distributed generators by comparing with the traditional distributed generators power-sharing method.
