Abstract

This paper presents a control method based on dynamic model of three-level neutral-point-clamped (NPC) voltage source converter (VSC) for integration of renewable energy sources (RESs) into the power grid. The proposed control method can provide continuous injection of active power besides the compensation of all reactive power and harmonic current components of loads through integration of RESs into the grid. Simulation results confirm a reduced total harmonic distortion (THD), increased power factor of the grid, and injection of maximum power of RESs to the grid. The proposed model is developed in Matlab/Simulink environment and emphasis is given to the challenges met during the modeling.
