Over the past two years, the technical committee responsible for IEEE 1547, Standard for Interconnecting Distributed Resources with Electric Power Systems, has added a section on power quality (PQ), including the parameters, indexes and limits on those for distributed energy resources (DERs) connect

Mobile applications, an increasingly fluid workforce and improvements in product integration are changing the landscape of mass notification systems (MNSs) and emergency communications. The technology is more responsive and better directed in messaging to the masses.
