逆变器侧电流反馈的LCL并网逆变器电网电压前馈控制策略
A Full Grid Voltage Feed-forward Control Strategy With Inverter-side Current Feedback for LCL Grid-connected Inverters
摘要
Abstract
The LCL grid-connected inverter, which uses the inverter-side current as feedback parameter, has many advantages, such as stronger stability, single-current loop, easy design for control parameters and its low cost. However, the grid current is controlled indirectly, which causes the power factor at grid-side is less than 1. Moreover, the grid current contains a lot of low-order harmonic, which results from low-order harmonic in grid voltage. A full grid-voltage feed-forward was proposed to overcome its shortcomings and reserve its merits, which can cancels out the effect of grid voltage on grid current and the power factor at grid-side is approximately equal to l.The simulation and experimental results verify that the performance of proposed control strategy is excellent.关键词
