Overview

When referring to the power industry, grid is a term used for an electricity network, which may support all or some of the following four distinct operations:

• Electric generation
• Electric power transmission
• Electricity distribution: smart grid is a form of electricity network utilizing digital technology. A smart grid delivers electricity from suppliers to consumers by means of two-way digital communications, which provides for the control of appliances at consumers' homes; this capacity saves energy, reduces costs and increases reliability and transparency.

A smart grid is made possible by applying sensing, measurement and control devices with two-way communications to electricity production, transmission, distribution and consumption parts of the power grid that communicate information about grid condition to system users, operators and automated devices, making it possible to dynamically respond to changes in the grid condition.
A smart grid includes an intelligent monitoring system that keeps track of all electricity flowing in the system. It also has the capability of integrating renewable electricity such as solar and wind. When power is least expensive, the user can allow the smart grid to turn on selected home appliances such as washing machines or factory processes that can run at arbitrary hours. At peak times, it could turn off selected appliances to reduce demand.

Smart energy demand is a broad concept. It includes energy-user's actions like:

• Enhancing reliability
• Seducing peak demand
• Shifting usage to off-peak hours
• Lowering total energy consumption
• Actively managing electric vehicle charging
• Actively manage other usages to respond to solar, wind, and other renewable resources
• Buying more efficient appliances and equipment over time based on a better understanding of how energy is used by each appliance or item of equipment

To address the above special requirements of Smart Grid, IEC TC57 has created a family of international standards. These standards include IEC61850 and IEEE 1613, which was devised for substation automation.
The Challenges

• Reliable and secure Power Grid network
• Improving efficiency of the Power grid network
• Real time control on power demand and supply
• Support TDM and packet services in single unified network
• Reducing the CAPEX to allow metering/sense/control on every site
• Smart Grid Protocols are on early stages, products must be future proof for protocol and Software changes
• Zero admin and minimal need for technical support on the field (maintenance free)
