    Abstract

    Power generation is shifting towards renewable and distributed energy production due to increased awareness of climate change and the recent advancements in renewable technologies. Distributed energy generation typically consists of wind and solar power plants, virtually all of which are connected to power grid by an inverter. As a consequence, the stability issues generated by the active power electronic devices are continuously increasing. The increased requirements for the functionality of the grid-connected inverters require a sophisticated test bench for experimentation. Power hardware-in-the-loop methods allow combining of the simulations to actual hardware, and thus, enable running experiments on real devices in time-varying conditions. This paper presents the use of a power hardware-in-the-loop test bench for stability studies of grid-connected systems. Experimental MIMO measurements based on pseudo-random sequences injected with a three-phase grid-connected inverter are presented and used to demonstrate the effectiveness of the proposed method.
