© 2015 IEEE. Development of control strategies for grid connected power converters is a fundamental aspect for applications such as integration of renewable energy sources, motor drives and energy storage systems. Hence, this topic has received significant attention from both academic and industry researchers. This paper presents the use of the Reduced Optimal Switching Sequence Direct Power Control (ROSS-DPC) together with a dynamic voltage reference design strategy for grid connected power converters. This predictive controller allows the converter to regulate the dc-link voltage reference and to track the instantaneous active and reactive power commands. Simulation results validates the proposed control strategy, which provides high performance during both transient and steady states.
