摘　　要：分布式发电供能技术是当代智能微电网的重要组成部分,其中三端口隔离型直流变换器发挥了重要作用。因为蓄电池储能系统可以实现能量的流动和储存,所以三端口隔离型直流变换器与光储供电系统相结合可以实现能量的多方向流动。为了实现上述目的,研究并设计了一种包含光储供电系统的三端口直流变换器系统,研究采用的方法是根据现实中存在的工作场景分析出三端口变换器不同的工作状态,其中包括了光伏输出、蓄电池和直流负载的工作状况分析,并在传统移相控制和光伏最大功率跟踪控制相结合的基础上,相对应地设计了不同的控制方法,通过控制策略实现了系统内的能量流动和协调管理。最后,进行了模型的搭建和验证,验证了工作场景分析及能量流动协调管理的可行性。Distributed power generation technology is an important part of modern smart microgrid,in which three-port isolated DC converter plays an important role.Because the storage battery system can realize the flow and storage of energy,so the combination of three-port isolated DC converter and photovoltaic power generation and energy storage power supply system can realize the multi-direction flow of energy.In order to achieve the above purpose,a DC converter including photovoltaic power generation and energy storage power supply system of the three-port system was studied and designed,the research methods were based on real work scenarios that exist in the analysis of three-port converter different working condition,including the photovoltaic output,the working condition analysis of storage battery and DC load.Based on the combination of traditional phase shift control and photovoltaic maximum power tracking control,different control methods were designed to realize the energy flow and coordination management in the system through the control strategy.Finally,the model was built and verified to verify the feasibility of work scene analysis and energy flow coordination management.
