“…km only 10% has been analyzed and it has been found that more than 3,000 MW of electricity could be generated with consideration of the installed capacity of 5 MW/km 2 .The commercially viable wind potential of the country is estimated to be only about 448 MW. This analysis shows that 3000 MW of electricity could be generated from wind energy with consideration of 10% of the area within the boundary of 10 km from current national grid and with more than 300 W/m 2 wind power density in Nepal [2][3][4][5].…”

The adaptation of renewable energy has been increasing in a very encouraging way all over the world. Among various renewable energy resources, wind and solar energy are the promising sources of alternative energy. Wind and solar photovoltaic (PV) have been employed in parallel as a hybrid system for better electricity service. This paper presents a case study and modeling of wind-solar hybrid system in Hriharpur Gadi village, Sindhuli District, Nepal. The hybrid system yields 110kWh of energy per day meeting the village’s electricity demand of 87 kWh per day. Moreover, the hybrid power system with battery storage system is modeled using MATLAB simulator. Further, improvising in the existing modeling has been presented to enhance the efficiency and effectiveness of the system.

“…Pradhan and Karki [13] assessed the probabilistic dependability of an off-grid small hybrid electric system based on PV-wind for electric power supply in Nepal's rural villages [9]. Hydro storage-based IRESs may be better options for isolated zones [14], while IRESs with PV-WT are significant for areas more than 50 kilometers from the electric power supply grid.…”

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

Establishing robust infrastructure and securing a sustainable power supply can be costly and time-consuming. Localized power generation from natural resources through integrated renewable energy systems (IRESs) offers a solution. This study explores the reliability and key statistics of an IRES incorporating solar photovoltaic modules, wind turbines, and battery banks. The failure and repair rates follow an exponential distribution due to the increased risk in integrated structures. Neural networks (NN), particularly the feed forward back propagation neural network (FFBPNN), enhance the consistency and precision of reliability parameters. The learning process of FFBPNN adjusts neural weights, improving parameter values. Utilizing the MATLAB algorithm, this study iterated until achieving accuracy close to 0.0001. The proposed system's real-time operations can be effectively managed by analyzing operational costs and system sensitivity to different parameters.

“…The necessity of appending storage systems to the generated wind energy has also been affirmed by these papers, but with the emphasis limited to large amounts of energy without concern for flexibility. The authors in [15] have also derived indices such as LOLE, expected energy not supplied (EENS) and energy index of reliability (EIR) to evaluate the probabilistic reliability of off-grid hybrid solar PV-wind power system for the rural electrification in Nepal. This is also concerned with large amount of energy that is uneconomical for deployment in vehicular networks environments.…”
