    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 growth of the renewable energy sector with solar energy resources playing a pivotal role, the proliferation of waste generated from the industry is a cause for concern. Globally the installed solar capacity is over 500 GW and is expected to rise further to 5000 GW by 2050. This phenomenal growth is expected to generate huge solar waste of up to 15% given the anticipated life span of 25 years. While the recent trends in solar research are aimed at improving little efficiency importance​ is given to waste disposal of dismantled solar power panels. Though recycling is an option, few companies are capable of handling recycling efficiently. To address this problem while ensuring environmental conservation and resource availability & recycling, the technologies adopted in the field are discussed and reviewed in this article. By 2050 60 million tons of solar waste will be there if it is not recycled properly. There view provides an in-depth assessment and the various technical aspects of the solar panel waste recycling and recovery, environmental protection, waste management. The economics of solar power recycling, impact on health and environmental and policies are discussed to ensure feasible and non-toxic technology for further development.

    Abstract The growing energy demand places its focus on renewable energy resources as a sustainable energy resource. Wind Power is one of the important sources of renewable energy. However, it exhibits challenges in the form of stability and control when integrating with the conventional grid. Though the connection of wind power plants does not require any major redesign, it is, however, necessary to ensure that issues are taken care of through control and compensative devices, to enable the grid to recover from grid faults and system disturbances. One such proposal is discussed here. This paper analyses the design and implementation of Proportional-Integral (PI) controlled Static Synchronous Compensator (STATCOM) controllers and is compared with Fuzzy Logic Controlled(FLC) STATCOM controllers. These controllers are primarily used to stabilize the voltage in wind power plants by preventing tripping of Wind Generators (WG) in the event of a grid side disturbance or fault and can recover from the fault by injecting reactive power in the grid. This paper applies STATCOM for restoring the voltage levels at the terminals of the wind power plants and simulated using MATLAB Simulink. It is observed from the simulation results, that STATCOM with fuzzy logic controls tends to reduce the voltage fluctuation and ensure the stability of the system as compared to STATCOM with PI.
