基于分布式微网能量管理框架,提出一种光储水柴微网经济调度策略,包括预测层、调度层和控制层。预测层提供能量管理相关决策数据;调度层采用边际成本竞价机制,通过光伏和水电电价补偿策略,合理分配光水资源,减少柴油发电机的发电比例;控制层包括稳态控制和紧急控制,其中稳态控制策略用于控制本地设备跟踪调度计划运行,而紧急控制策略用于对系统可用发电容量进行分配,以维持系统功率平衡。以实际光储水柴微网为例,对比实际运行数据,所提出的调度策略在充分利用光水资源的基础上,保证了系统稳定运行。
基于分佈式微網能量管理框架,提齣一種光儲水柴微網經濟調度策略,包括預測層、調度層和控製層。預測層提供能量管理相關決策數據;調度層採用邊際成本競價機製,通過光伏和水電電價補償策略,閤理分配光水資源,減少柴油髮電機的髮電比例;控製層包括穩態控製和緊急控製,其中穩態控製策略用于控製本地設備跟蹤調度計劃運行,而緊急控製策略用于對繫統可用髮電容量進行分配,以維持繫統功率平衡。以實際光儲水柴微網為例,對比實際運行數據,所提齣的調度策略在充分利用光水資源的基礎上,保證瞭繫統穩定運行。

A novel energy management system of microgrid based on distributed control is presented,consisting of prediction layer,dispatch layer and control layer.By applying to photovoltaic-battery-hydro-diesel hybrid microgrid system,the concept of dispatch strategies is described in detail.Considering the specialty of photovoltaic and water resources,a proper schedule is given by dispatch layer based on bidding model.Then at the control layer,the components follow the dispatch schedule according to its own operation strategy.The power balance is guaranteed by reserve power allocation at the system level.A real photovoltaic-battery-hydro-diesel hybrid microgrid system is studied as an example.Simulation results demonstrate the performance of the proposed strategies on the dispatch of photovoltaic and water resources compared with practical operating data.
