Ideas / Definitions of Smart Grid

“Auto-balancing, self-monitoring power grid that accepts any source of fuel(coal, sun, wind) and transforms it into a consumer’s end use (heat, light, warm water) with minimal human intervention.”

“A system that will allow society to optimize the use of renewable energy sources and minimize our collective environmental footprint.”

“It is a grid that has the ability to sense when a part of its system is overloadedand reroute power to reduce that overload and prevent a potential outage situation.”

“A grid that enables real-time communication between the consumer and the utility, allowing the consumer to optimize energy usage based on environmental and/or price preferences.”

Why Condition Monitoring?

Loss of expertise

Condition monitoring:1. enables effective prediction and, thus, failure avoidance2. offers a possibility for safe use of assets at higher loads and, therefore,

supports both asset management and operation

Cutbacks on expenditureRetirementsDownsizing
