MULTI-BUILDING CONTROL FOR DEMAND RESPONSE POWER USAGE CONTROL

摘要

An energy usage coordinator controls the energy usage of individual buildingsof a group (or portfolio) of buildingsin one or more load zones These buildings have all contracted with an energycompany which controls (directly or indirectly) theenergy usage coordinator By agreeing to lower energy usage during times ofpeak usage (when the energy company may otherwisehave to pay very high pnces on the spot or short term market), the owners ormanagers of the buildings receive a preferential energyrate from the energy company The preferential rate may be a fixed orva.pi.able rate reduction Alternatively, the energy company maydetermine that energy is currently selling for twice what its buildingportfolio has contracted to pay, so it requests some portion ofthe portfolio to reduce usage so it can sell the excess/saved energy in themarket.
