Abstract: Due to the increasing demand for energy, the current approach of obtaining energy from fossil fuels is insufficient, resulting in significant environmental destruction. As a result, switching to unconventional energy sources is being given more consideration. Due to the global transition to renewable energy sources, distributed generation is now used to produce electricity regionally. MATLAB/Simulink is used for the simulation-based integrated renewable energy system model. The hybrid microgrid is made up of resistive loads, Nickel Metal Hydride (NiMH) battery storage, and renewable generators like solar and wind. The created system functions as an entirely carbon-free microgrid. The solar PV generator is connected to the hybrid microgrid using Buck converter, whilst the wind generator is connected with Wind Maximum Power Point Tracking (MPPT). Bidirectional Converter (Buck-Boost) is used to link the battery to the microgrid, allowing for both charging and discharging in order to balance supply and demand. Depending on the availability of renewable power generators, electricity is transferred from the DC bus to the loads and between the loads (including dump load) and batteries. To assess the efficacy of the suggested technique two scenarios were examined.
