摘要

本研究代表一个独立的光伏(PV)系统的控制。它主要关注基于光伏的单相不对称多电平转换器(AMLC)，用于较少半导体开关的独立应用。常用的最大功率点(MPPT)算法即增量电导用于跟踪光伏板的最大功率。同步双向buck-boost dc-dc转换器(BDC)用于电池和负载之间的电源管理。BDC参数是基于连续导通模式(CCM)设计的。三个具有MPPT和BDC的独立光伏电源连接到单相AMLC。AMLC的各个直流链路电压由BDC控制器控制。完整的系统是在MATLAB Simulink平台上开发的。通过OPAL实时结果验证了结果的正确性。

Decoupled Control of Asymmetrical Multilevel VSI for Standalone PV Application

This study represents the control of a stand-alone photovoltaic (PV) system. It mainly focuses on PV based single-phase asymmetrical multi-level converter (AMLC) for standalone applications with less semiconductor switches. A popular maximum power point (MPPT) algorithm i.e incremental conductance is used to track maximum power from the PV panel. Synchronized bidirectional buck-boost dc-dc converter (BDC) is used for power management between the battery and the load. BDC parameters are designed based on continuous conduction mode (CCM) of operation. Three individual PV sources with MPPT and BDC are connected to single-phase AMLC. The individual dc-link voltage of AMLC is controlled by BDC controller. The complete system presented here is developed in MATLAB Simulink platform. Validation of the results has been tested by OPAL- real-time results.
