Abstract
In this work, the integration of renewable hybrid energy (RHE) resources using extendable multiport DC–DC boost converter is investigated. Three renewable energy sources such as solar photovoltaic (PV) system, wind energy system and fuel cell (FC) are integrated into the grid via this converter and grid-tied inverter. The output voltage of the multiport DC–DC boost converter is controlled using adaptive neuro fuzzy inference system-based controller. The overall system model is developed and tested in the MATLAB simulation software and also implemented in real time. The overall system is tested for different operating conditions such as change in irradiance condition of the solar PV panel, change in wind speed condition of the wind turbine, change in hydrogen pressure conditions of the FC and sudden change in load conditions and corresponding results are measured and analysed. The efficiency of the proposed system is about 98.21%. Finally, experimental results of the proposed model are also presented to examine the suitability of the system.
Highlights
The need for electrical power is extremely important due to an increase in world population, residents and industries
Constant input parameter conditions with constant load In these conditions, irradiance and cell temperature of the PV panel are fixed at 1000 W/m2 and 25°C, wind speed of the wind turbine (WT) is fixed at 12 m/s, fuel pressure of the fuel cell (FC) stack is fixed at 1 atm and load is fixed at 1500 W
Sudden change in irradiance variations in solar PV system In these conditions, irradiance of the PV panel varied from 1000 to 500 W/m2 at 1 s, and the temperature is fixed 25°C, wind speed of the WT is fixed at 12 m/s, fuel pressure of the FC stack is fixed at 1 atm and load is fixed at 1500 W
Summary
The need for electrical power is extremely important due to an increase in world population, residents and industries. Fossil fuels always created the problem for the environment and disturbed the ecological structure of the world. 34.6% of using renewable energy sources was installed in India. These resources are frequently employed since they are efficient and inexpensive, and the overall amount of energy consumption is increasing daily. The proposed hybrid system provides excellent solution for future electricity demand. Both solar and wind power generation systems are best sources, which brings the CO2 level down from the atmosphere
