Optimized Dc-link Control and Protection Framework for Solar Photovoltaic Microgrids

Abstract: This work presents a cohesive strategy for DC-link voltage regulation and protection specifically designed for microgrid applications. The suggested method keeps the DC-link voltage stable during load changes and AC-side fault events. It also protects the DC-link in case of a short circuit in the DC section. A microgrid test model that followed IEEE 1547 standards was used in PSCAD/EMTDC simulation software to see how well this strategy worked. The system was tested under a variety of fault conditions, which made it possible to fully evaluate its performance. The simulation results show that the suggested method works to stabilize the DC link voltage during both AC- and DC-side disturbances, whether the system is connected to the grid or not. The scheme can keep the DC-link's voltage control and protection strong across a wide range of operating conditions and fault conditions.
