摘要

To avoid the instability of micro-grid operation,research on control strategy for super capacitor bank energy storage device connected to the micro-grid is carried out.Energy storage device connects DC/AC converter by super capacitor bank throughing bidirectional DC/DC converter,through filtering,even after boosting connect into grid.By studying on control of bidirectional DC/DC converter sliding mode,it makes it possible to work under any operating conditions,and to analyze on running stability.Bye Matlab,Simulink simulation model for energy storage system is built to verify the feasibility of the control strategy.%为改善微网运行不稳定的问题,针对与微网连接的超级电容器组储能装置的控制策略进行研究.储能装置由超级电容器组通过双向DC/DC变换器连接DC/AC变换器,通过滤波、升压后连入电网.通过对双向DC/DC转换器滑模控制的研究,使得任意操作条件均能正常工作,同时对运行中的稳定性进行了分析.最后,在Matlab中Simulink搭建储能系统仿真模型,验证了本文控制策略的可行性.
