Smart Grid & Demand / Response
What is the Smart Grid?
Use of digital information and controls to improve reliability, security and efficiency of the grid.
Use of smart automation systems that optimize the operation of buildings and homes.
Installation of smart meters to enable real time pricing
Deployment of demand / response
The Problem Energy Demand Coal Hydro Renewables Diesel Peaker Gas Turbine Spot Market $.04 $.06 $.10 $.25 $.30 $2.00 Energy Cost
Efficiency Original load Building power consumption - kw With energy efficiency 250 kW reduction
Demand / Response Original load Building power consumption - kw With energy efficiency With demand response
Auto Demand Response Demand Response - a utility requests energy curtailment during an anticipated peak period where demand exceeds supply. Utility options are: Purchase power on the spot market Start up old generation plants Build new power plants (very costly) Rolling blackouts Demand / Response Auto DR is an automated way to achieve demand reduction.
