IIi.features Of A Smart Grid

III .FEATURES OF A SMART GRID Reliability The smart grid uses technology to self locate faults so their rectification is fast and sound. This self healing property of smart grid makes it more reliable than the conventional grid. Main technology used here is state estimation. Multiple routes are used in a smart grid which were used in the old grid as well. But mostly they were radial in nature so that any failure can cause total failure of the system and the current would be shunted to other elements. Flexibility in network topology Next generation grid technology would be far more flexible in transferring two way energy by allowing for distributed generation from solar cells, fuel cells , electric vehicles, wind turbines . Classic one way distribution is not that flexible to cater to problems when load is higher than the generating end . By using smarter grid this is possible. Efficiency Numerous contributions to overall improvement of the efficiency of energy infrastructure are anticipated from the deployment of smart grid technology, in particular including demand-side management, for example turning off air conditioners during short-term spikes in electricity price, reducing the voltage when possible on distribution lines through Voltage/VAR Optimization (VVO), eliminating truck-rolls for meter reading, and reducing truck-rolls by improved outage management using data from Advanced Metering Infrastructure systems. The overall effect is less redundancy in transmission
