Security Issues in IoT: Challenges and Countermeasures
Poor physical security 10. IoT application security and end point security are the biggest concerns. Poorly secured IoT devices and applications make IoT a potential target of cyberattacks. Application developers or manufacturers that create IoT products are not mature from a security standpoint.
Energy characteristics of a fixed-speed flywheel energy storage system with direct grid-connection …
Flywheel energy storage systems (FESSs) store kinetic energy in the form of Jω 2 ⁄2, where J is the moment of inertia and ω is the angular frequency. Although conventional FESSs vary ω to charge and discharge the stored energy, in this study a fixed-speed FESS, in which J is changed actively while maintaining ω, was demonstrated.
Grid-Connected Renewable Energy Systems
A grid-connected system allows you to power your home or small business with renewable energy during those periods (daily as well as seasonally) when the sun is shining, the water is running, or the wind is blowing. Any excess electricity you produce is fed back into the grid. When renewable resources are unavailable, electricity from the grid ...
