PEM Fuel Cell based PV/Wind Hybrid Energy System

Due to the rapidly rising energy consumption, depleting fossil fuel resources, global warming, and harm to the environment and ecosystem, there is a greater need for clean, sustainable energy sources, such as wind, solar, biomass, and others, that are highly efficient and require little maintenance. Among all renewable energy sources, photovoltaic and wind energy have the most potential as a source of power generation. This is due to their numerous advantages, such as their endless supply, ease of access and electrical conversion, minimal or no polluting gas emissions, and low cost. This article models and simulates a single gridconnected wind and PV hybrid power system. This hybrid system is made up of a wind turbine system, an external fuel cell, and a PV system that share a DC bus. When combined with renewable energy sources, fuel cells can create an efficient system that can supply power for longer periods of time. Major power quality problems for both grid-connected and standalone systems include harmonics, voltage and frequency fluctuation, and they have a greater impact on weaker grids. The system was developed in MATLAB Simulink, and by analyzing the results, the effectiveness of the system is increased.
