Control Strategy of Grid-connected Converters With LCL Filter Based on Discrete State-space Model
摘要
Abstract
In order to reduce the switching frequency harmonics caused by the grid-connected convener, the LCL filter is adopted. However the third-order LCL filter, as an undamped system, is not stable. In order to overcome this problem, a damping resistor and the active damping method are often used; but the damping resistor will result in the power consumption, and the method of active damping needs more sensors compared to the standard control.关键词
