多能源联合供电系统电路结构与能量管理策略

摘要

The power supply system with single kind of new energy is generally unstable,discontinuous and changed with the weather.In order to improve the continuity and stability of the system,the multi-energy joint-power-supply system is adopted.The two-stage multi-input DC/DC converter mode multi-energy joint-power-supply system is analysed,then an improved two-stage multi-winding power-simultaneously DC/DC converter mode and the quasi-singlestage multi-input DC/DC converter mode multi-energy joint-power-supply system are presented.Their circuit structures,circuit topology examples,energy management strategies and a design example are given,which will provide a guidance to the research and application of the multi-energy joint-power-supply system.%单一能源供电系统通常存在电力供应不稳定、不连续、随气候条件变化等缺点,为提高供电系统的稳定性和灵活性,需采用多种新能源联合供电系统.在论述了两级多输入直流变换器型多能源联合供电系统的基础上,提出了一个改进型两级多绕组同时供电直流变换器型和一类准单级多输入直流变换器型多能源联合供电系统,并给出了两类系统的电路结构、拓扑实例、能量管理策略和设计实例,对多新能源联合供电系统的研究和应用具有参考意义.
