Energy-Efficient Hybrid Power System Model Based on Solar and Wind Energy for Integrated Grids

Abstract

Global energy needs have risen in recent years, and traditional energy sources such as fossil fuels are no longer viable. To meet the growing electricity demand, attention has moved to renewable energy sources such as solar and wind energy. Furthermore, the development of clean energy is vital for combating climate change. Various studies have shown the effectiveness of using hybrid systems (combination of solar photovoltaic and wind energy systems) for generating power. However, a significant amount of energy gets wasted. To prevent the wastage of energy, a dual-energy generation system for integrated grids has been suggested in this paper. The load data have been collected from various regions in Rajasthan, India. An optimal grid system configuration is designed using net present cost and cost per unit of energy. Other factors such as the tilt angle of PV array optimization, wind energy, and inverter optimization have also been used for increasing the reliability and stability of the system. Sensitivity analysis has been performed to analyze the effective variations of the capital costs on the developed system economy. The results obtained from the simulations show that the overall costs of generating electricity from diesel systems and nongrid-based systems have been reduced to 20% at 10% annual capacity shortage allowance. Upon cost analysis, we found that the total cost for installing the suggested system is 49,500 USD, whereas for other systems, the costs came out as 66,000 USD, 56,500 USD, and 56,300 USD, respectively.

Enhancing infrastructure sustainability: reliability and sensitivity analysis of localized integrated renewable energy systems using feed forward backpropagation neural network

“…The study suggested that the optimized PV/battery/thermal storage system could not meet the entire energy demand, needing additional sources of heat and power. Jha et al [29] proposed a dual-energy generating system integrated with a grid to reduce energy waste. The load data was compiled from several areas of Rajasthan, India.…”

Technoeconomic Analysis and Optimization of Hybrid Solar-Wind-Hydrodiesel Renewable Energy Systems Using Two Dispatch Strategies

“…Also, the study mentioned that the CC method minimized the financial indicators of the optimal solution more than other strategies. Some other relevant studies of the technoeconomic feasibility of HES have focused on three major groups, comparison procedures [27], design and planning [28][29][30], and energy management [31,32]. The project lifetime in all of these research articles has been set at 20 or 25 years, with no consideration of the impacts of reducing the project's lifetime.…”
