Smart power grid demands innovative design

Smart meters communicating with a smart network will allow the utility to implement a variety of control and incentive programs, such as real-time variable pricing. The consumer can be warned when a peak loading rate is being charged with features like in-home energy displays or eco-panels. They can then make an informed choice to switch off appliances such as dryers and postpone their use until a lower rate is available. The rescheduling of high consumption functions can be controlled directly by the utility through the smart meter with smart appliances or Demand Response Units (DRUs) controlling appliances in the home. The communication handling in smart meters must be both flexible and upgradable to accommodate differing regional and local requirements and standards. Security is also important to prevent unauthorized intrusion to consumer's data. The power supply must work efficiently over a wide dynamic range with fast response to changing demands when transmitting data or fulfilling other functions.
