一种混合储能微电网离并网控制技术研究
A grid or off-grid control technology in hybrid energy storage micro grid
摘要
Abstract
In microgrids,the system tends to be instability when grid power or the local load mutation occurs.This study try to provide the stability of such system by combining the super capacitor and battery hybrid energy storage.In the DC side,the control strategy of Low Pass Filter (LPF) is used to charge-discharge for the super capacitor and battery in order to stabilizing DC bus voltage.And in the AC side,a grid or off-grid control strategy is used to ensure non-impact on inverter.In grid runtime,inverter can be as corresponding active power or reactive power depending on the grid instruction,while in off-grid runtime,inverter can make voltage quality meet the demand of the power in local load.We also test and verify the above control strategies by a hardware system.The results shows that such control strategies in super capacitor and battery hybrid energy storage are effective,which improve the stability of system.关键词
