Smart Grid and Power Line Communication (PLC)
CEVA's DSP Cores Support the Smart Grid Wired and Wireless Communication Requirements
The traditional electric infrastructure is very non-intelligent. Each house has a meter which records the use of electricity, requires periodical visits and does not support any communication with the utility’s central office. A new infrastructure known as the Smart Grid is currently under deployment. The Smart Grid not only automates meter reading; it can predict and intelligently respond to the behavior and actions of all electric power users connected to it - including suppliers and consumers. All of this involves a lot of data collection, communication, and processing. For example, each device on the network can be given sensors to gather data (power meters, voltage sensors, fault detectors, etc.), plus two-way digital communication between the device in the field and the utility’s network operations center. In addition, two-way communication will be established between the smart meter and smart home appliances allowing users to remotely control their appliances and their power bills.
A typical wired communication method in the Smart Grid is Power Line Communication (PLC), which refers to transmitting data on the same conductor that is used for electric power transmission. One problem with PLC is the amount of electrical noise that may be encountered, which therefore requires the use of sophisticated error detection and correction techniques.
In addition to wired communications using PLC, the smart grid may also employ wireless communications in the home (WiFi, ZigBee…) and between smart meters. Also, LTE and WiMAX for transferring data back to the utility backhaul. This market is very fragmented, thereby mandating a programmable solution that can address the unique requirements of diverse systems. Furthermore, elements in the smart grid cannot be replaced every few years; they need to be kept in service for decades with minimal maintenance. Once again this mandates a software programmable solution that facilitates remote upgrades to address evolving requirements.
