Operation of Dual MPPT Enabled Hybrid Microgrid under Variable Irradiation Conditions and its Positive Impact on Stability of AC Conventional Grid

Abstract

The growing population, technological advancements, and heightened economic activities drive a greater demand for energy within the AC conventional grid. However, this energy demand can be met by utilizing renewable energy sources such as solar, wind, and biomass. These alternative energy sources generate electricity influenced by varying input factors, such as solar irradiation and temperature for photovoltaic systems, as well as wind speed and pitch angle for wind turbines. Among these factors, solar irradiance is the most unpredictable, affected by numerous environmental influences such as air pollution, cloud cover, and changing weather patterns. As a result, photovoltaic arrays have a significant impact on energy production, thereby affecting the stability of the traditional AC grid as it seeks to meet the increasing power demand. This paper proposes a solution to enhance the stability of the AC conventional grid through a novel hybrid microgrid that integrates dual MPPT-enabled photovoltaic and wind turbine generators, particularly during peak load conditions.
