    Abstract Distributed generators (D.G.'s) enable us to generate, supply and be self-reliant on power while also allows us to supply power to meet the demand through virtual power plants. The virtual power plants also help us analyse, control, optimise, and help bridge the gap of demand and supply in these vast energy requirements. With this also comes challenges associated with securing physical systems, data protection and information privacy. Recent technological advancements have aided cybercriminals to disrupt operations by carrying out deliberate attacks on the energy sector. Though security researchers have tried to mitigate the risks, vulnerabilities, and it remains a challenge. This paper aims to present a comprehensive Edge-based security architecture to help reduce the risks and help secure the physical systems and ensure privacy and data protection.

    Abstract The declaration of COVID 19 as pandemic has impacted the society at large. In what started with 17 cases in Wuhan spread its tentacles and has now over 4 million cases across the globe. In this rapidly changing environment, it is extremely difficult to quantify the impacts that the virus has on many aspects of society. The paper highlights the various challenges and the impact on society, economy and general health. These are only initial levels impacts, and it goes on with greater implications on growth depends on many factors, including the social distancing norms and shutdown rules laid by countries. Nonetheless, it is clear that the virus is here to stay and is likely to impact growth, health and society substantially.

    Abstract Worldwide significant efforts are ongoing to develop devices that store solar energy as fuels. In one such approach, solar energy is absorbed by semiconductors and utilized directly by catalysts at their surfaces to split water into H2 and O2. To protect the semiconductors in these photo-electrochemical cells (PEC) from corrosion, frequently thin TiO2 interlayers are applied. Employing a well-performing photoanode comprised of 1-D n-Si microwires (MWs) covered with a mesoporous (mp) TiO2 interlayer fabricated by solution processing and functionalized with α-Fe2O3 nanorods, we studied here the function of this TiO2 interlayer by high-energy resolution fluorescence detected X-ray absorption near edge structure (HERFD-XANES) spectroscopy, along with X-ray emission spectroscopy (XES) and standard characterization techniques. Our data reveal that the TiO2 interlayer not only protects the n-Si MW surface from corrosion, but that it also acts as a template for the hydrothermal growth of α-Fe2O3 nanorods and improves the photocatalytic efficiency. We show that the latter effect correlates with the presence of stable oxygen vacancies at the interface between mp-TiO2 and α-Fe2O3, which act as electron traps and thereby substantially reduce the charge recombination rate at the hematite surface.

    Abstract Improving interfacial contact between each component in the proton exchange membrane fuel cell (PEMFC) can lead to a significant increase in power density and Pt utilization. In this work, the junction between the catalyst layer and gas diffusion layer (GDL) is greatly enhanced through direct attachment of helical carbon nanofibers, giving rise to a hierarchical structure within the electrical interconnections. The alternative novel GDL is produced by spraying a thin layer of Pd

    Abstract The growth of renewable energy technologies as an alternative source of power is a great boon to the rural masses where energy is predominantly a challenge. This paper focuses on studying the microeconomic benefits of the virtual power plant as a solution to the rural masses who either have no access to energy or has limited access. The model here uses HOMER as a tool for modelling the design. The simulation results discuss the profitability of the virtual power plant as a solution not only to the virtual power plant operator but also to the rural households while ensuring a sustainable income source with the use of solar power PV as a generator.
