摘要

本文介绍了采用两级配置的太阳能/光伏系统与交流电网的集成。升压变换器和电压源变换器是光伏组件与电网之间的两级接口。光伏模块采用3二极管模型实现，该模型级联到升压变换器，升压变换器将PV输出电压放大到受控直流链路电压。升压转换器输出电压被馈送到一个三相VSC，它将这个电压转换成交流电，以便被馈送到电网。为了控制输电网的功率，需要根据k因子设计合适的控制器。

A Novel Scheme for Integration of PV System with AC Grid

This paper describes the integration of solar/photovoltaic system (PV) with an AC grid using a two stage configuration. Boost converter and voltage source converter (VSC) are the two stages of interface between PV module and grid. A PV module is implemented using 3-Diode model which is cascaded to the boost converter which amplifies PV output voltage to controlled dc link voltage. The boost converter output voltage is fed to a 3-phase VSC which converts this voltage into ac in order to be fed to the grid. To control the power fed to the grid, appropriate controllers are needed which have been designed based on k-factor.
