直流汇流型户用微电网并网逆变器控制策略研究

Research on control strategy of DC microgrid connected inverter for household in rural area

综合考虑偏远地区负荷供电和电能质量较差的问题,文章设计了适用于户用级别的微电网结构,并根据设计的微电网结构类型研究并实现了户用微电网的能量管理控制策略。该控制策略主要基于用户侧的功能需求分析,优先使用直流侧风光发电资源,实现了能量的最优化利用。

Taking problems of load supply and poor power quality in rural areas into account,a structure of microgrid for household is proposed, a detailed scheme of the structure is presented in this paper.An energy management and control strategy are designed according to the structure of microgrid for household that are mentioned above. This control strategy, which analyzes requirements of user-side,could give priority to the inverter in absorbing DC-side distributed energy to achieve optimal utilization of energy.
