Overview of Current Control Strategy for Grid-Tied Inverters with LCL Filters
摘要
Abstract
Grid-tied inverters are the commonly-adopted interface between renewable energy power generation, micro-grid and the utility. The control of injected grid current is one of the key technologies. Generally, with LCL-type filter, the switching harmonics in injected grid current can be effectively eliminated. However, current is easily resonated because of the resonance phenomenon associated with the high-order filter. Consequently, the design of the control is diflficult and has been concerned all over the world. In this paper, an overview of the current control for grid-connected LCL-filtered inverters is presented and evaluated. It consists of resonance phenomenon and its rejection strategy, precise tracking control and grid applicability control. Furthermore, the prospect research focuses for grid-tied LCL-filtered inverters are given.关键词
