Hybrid Modular Multilevel Converter Based Single-Phase Grid Connected Photovoltaic System

RASHMI RANJAN BEHERA, Amar Nath Thakur

Abstract


This paper presents a new single-phase Hybrid Modular Multilevel Converter (HMMC) topology with reduced number of sub-modules and its application in grid integration of Photovoltaic (PV) systems. This HMMC has reduced switch counts as compared to other existing multilevel topologies and so has potential advantages like reduction in converter losses and size, high efficiency, fewer circuit complexities, and the cost. The modified ripple correlation control (RCC) based maximum power point tracking (MPPT) is used to extract maximum power from the PV systems. A control strategy has been proposed for the control of the injected active and reactive power to the grid. The overall system has been simulated using MATLAB/Simulink platform, and the results are presented to support the theoretical concepts about HMMC with the control scheme proposed for the specific application.
