The rapid shift toward renewable energy resources (RERs) has placed significant demands on traditional power systems. To address these challenges, modern energy infrastructure is evolving into smart grids, leveraging advanced technologies like Virtual Power Plants (VPPs) to enhance grid flexibility, reliability, and efficiency. A VPP is a collection of distributed energy resources (DERs), such as renewable energy sources, battery storage, controllable loads, and electric vehicles (EVs), that operate as a unified power plant through intelligent control and communication networks. By integrating VPPs with smart grids, the energy sector can better coordinate energy generation, storage, and consumption, facilitating a more resilient...

A personal fall protection arrest system (PFAS) is comprised of three vital components: an anchorage, body wear (full-body harnesses), and a connecting device (a shock-absorbing lanyard or self-retracting lifeline). The safety of at-height workers depends on these three components, and each one must be in place and used properly to provide maximum worker protection.
When discussing fall protection, anchorage connectors and full body harnesses receive a lot of attention. We don’t always stop to think about connecting devices like self-retracting lifelines or shock-absorbing lanyards, and yet these are the two components that bear the greatest forces during a fall.
Before...
