The energy consumption and economic growth of a country go hand-in-hand; hence, to uplift the living standards, every remote location should be powered by the necessary energy. However, to fulfill high demands with traditional sources may defeat the ongoing efforts of a zero carbon emission plan, which aims to eliminate greenhouse gas emissions by heavily relying on renewable energy sources (RES) like solar, wind, hydro, geothermal, and biomass. To facilitate the seamless connection of RES and energy storage systems with the main grid, converters play an important role. However, this integration introduces many challenges, such as low inertia of electromechanical devices, switching transients, harmonics, and mismatched time frames of different events. To analyze such hybrid grids, there are many attempts in the literature using simulation-in-loop or hardware-in-loop as two extreme end methods, resulting in either a theoretical solution away from reality or real-time simulation using hardware but having laboratory operating constraints. In view of this, the chapter proposes a trade-off approach by formulating and validating the model using Field Programming Gate Array (FPGA). The research also highlights how Simulink offers ease in methodology to perform testing of power electronics devices using the FPGA-in-the-Loop (FIL). This chapter utilizes ARTY A7 100T as the target FPGA board, and the chapter also shows quantitative analysis of resource utilization of the FPGA during the inverter testing.
