This study presents an experimental investigation of the proposed waterless photovoltaic (PV) cleaning mechanism in a semi-desert environment. The goal of this research is to improve the efficiency of the solar photovoltaic systems while reducing cleaning costs and avoiding the use of water, ensuring effectiveness and adaptability. In this paper, t...

Due to shading conditions, solar photovoltaic (PV) arrays deliver less power compared to ideal operating conditions. Moving clouds, nearby telecom towers, and trees, among other things, are the basic causes that come under partial shading conditions (PSCs). Furthermore, PV array characterization carries multiple maximum power points (MPP) on the P-...

Solar photovoltaic (PV) technology can be considered a suitable option for fossil fuels because of its free availability and ease of use. The deprivation of power generation from PV systems due to environmental factors shows a major flaw in solar PV systems. As a result, they are unreliable in deserts or remote locations. The accumulation of dust i...

This study describes the designing steps of the proposed self-cleaning system for the photovoltaic (PV) system and experimentally investigates the effectiveness of the proposed self-cleaning PV sliding system for solar power plants under all Indian climate conditions. To investigate the performance of the proposed self-cleaning PV sliding system, w...

Electricity theft is one of the biggest concerns in the present energy sector. Controlling such a phenomenon is very challenging. It is a prime constituent of AT&C losses in the system. It is a very big concern from the energy perspective, especially the distribution companies. It affects the quantity and quality of energy used in the load. In this...

The electrical distribution grid is unremittingly vulnerable to natural disasters. Many researchers propose strategies mainly based on grid-side solutions to improve critical load's survivability during the targeted emergency period. However, the main agenda of resilience enhancement is to improve the overall system resilience. Therefore, this pape...

The performance degradation due to environmental factors represents a major shortcoming to the solar PV system making them untrustworthy for dessert or remote plants. Real-Time monitoring systems are extensively required in the remote PV system for gathering all parameters for estimating system performance and optimization purposes. Many existing s...

Among the various alternatives to fossil fuels, hydrogen and fuel cells have turned out to be the most consistent and promising. In this chapter, a review has been presented in terms of two major areas for fuel cell technologies to gain dominance in the energy markets: infrastructure and cost. An initial assessment of the existing technologies, bot...

In recent days, aiming for power generation with less carbon emission, led to the high penetration of renewable energy into the distribution grid. To improve the intermittency caused by renewables and to increase the grid flexibility, grid integrated Energy Storage Units (ESUs) are proposed as the promising solution in the literature. However, cons...

In the recent decade, a significant increase in the penetration level of renewable energy sources (RESs) into the distribution grid is evident due to the world's shift towards clean energy and to increase the reliability or inboard manner resiliency of electrical distribution system. RES based microgrids are most favorable option available, especia...

The power sector has been facing the problems of the continuous increase in demand and lack of sufficient generation of electric energy using fossil fuels. The environmental problems (pollution and global warming), the continuously increasing cost of fossil fuels and the shortage of fossil fuels are mainly concerned to harvest energy from sustainab...
