PERFORMANCE ANALYSIS OF MULTIFUNCTIONAL GRID CONNECTED CONVERTER UNDER DIFFERENT OPERATING MODES

The increasing utilization of renewable energy sources (RESs) plays a vital role within the modern grid. The high penetration of the RESs within the electric power network results in challenges to the system's stability. This paper presents a multifunctional grid connected converter, controlled using current loop control. The multifunctional converter acts as an interface between various non-conventional sources and also the grid. The battery is employed to either supply or store power surges or transients. Multifunctional features of the converter includes active power injection, active power compensation, reactive compensation, harmonics compensation and other modes. The validity of the proposed model is verified within the real-time simulation of Typhoon HIL software.
