A Technical Design for Smart-grid to Realize both Low Voltage Ride Through and Anti-islanding Protection

Abstract

Green energy has been an attractive and developing area for the whole world, the researchers are trying to tackle its drawbacks like uncertainty and effectiveness. This paper analyzes when the low voltage ride through and anti-islanding protection happened and why they can not coexist. By studying the reasons of voltage drop, the specific design was given in this paper, in which the detection of voltage and frequency can be done. A certain example also shown latter to prove the reliability and quality of the design, this paper also shows more possibilities of the design and its operating mode in other field.
