A theft deterrent technique for expensive smart grid device is proposed herein. The devices are paired together at the time when the devices are installed in a smart grid. The device upon removal from its location does not function. The device continues to remain non-functional until the device is repaired in a new location in the smart grid.
The present invention relates generally to a smart grid, and more particularly to a technique that prevents theft of smart grid device.
A smart grid delivers electricity from suppliers to consumers using digital technology to save energy, reduce cost and increase reliability and transparency. Smart grid is a complex system which includes several devices, such as, energy storage device, processor, sensor, generators, smart appliances, among others. The smart grid is a large system which is used to control electricity present in almost every home, offices, factories and several other utilities. Further, smart grid is considered as an important infrastructure by a government as several other vital infrastructures, such as, banks, emergency services such as hospitals, telecommunications, computers, are dependent on electricity from smart grid. Subsequently, failure or destruction of smart grid has a debilitating effect on security, national economic security, public health or safety, or any combination thereof of a country.
Smart grids utilize electronic smart meters which introduces threat of a cyber attack or alteration. Unique characteristics of smart grid make it important to provide cyber security of the smart grid. The primary concerns revolve around the security protections for smart grid meters that are physically accessed. It is difficult for utility to physically secure all meters from individuals who are intent on theft.
A conventional technique utilizes a system incorporated in meters that safeguards meters and alerts uti...
