Supplying stable and sustainable energy for power grids is one of the most important challenges in the power industry, due to its importance, power generation systems, must connect their production power to the grid in a controlled manner, which is necessary to maintain quality and stability. system, high power quality in terms of voltage, stable frequency, safety and efficiency are very important. In general, maintaining stability and balance between electricity supply and demand in the electricity network plays an important role in providing stable and sustainable energy. This paper uses a controlled battery-fuel cell assembly to power a two-feeder system. It has been shown that when the power exceeds the capacity of the fuel cell many times, the battery enters the scene and supplies power to the system in a controlled manner. The values of each feeder are non-linear, and in order to reduce the current harmonics caused by the presence of electronic power converters such as inverters and boost converters, a low-pass filter has been used. The system design and simulations were done using MATLAB/Simulink ver. 2021b software.
