Smart Grid Technology

A smart grid is an umbrella term that covers modernization of both the transmission and distribution grids.The concept of a smart grid is that of a “digital upgrade” of distribution and long distance transmission grids to both optimize current operations by reducing the losses,as well as open up new markets for alternative energy production India has a power grid that is ripe for renovation and transformation. More than a third of the nation’s grid electricity is lost to power theft and inefficiencies, and that doesn’t include the half of the population that has no grid electricity at all.

For those who do, daily blackouts are a common occurrence, and major system-wide failures, like last year’s blackout that left 600 million people in the dark, point to long-term challenges in matching power supply with booming demand. All of these problems spell opportunity for the smart grid industry. After years of stalled-out attempts to drive investment into grid transformation, India’s central government is now in the midst of its Restructured Accelerated Power Development and Reform Programme, or R-APDRP, which is directing roughly $10 billion over the coming years to grid modernization.

But India’s smart grid efforts likely won’t play out like those we’ve seen in Europe and North America. Specifically, the failures of India’s previous grid renovation projects have driven today’s R-APDRP program to start with systems to diagnose distribution grid losses in cities and towns across the country, along with proven progress in lowering those losses, before bigger investments can go forward. In other words, big deployments of smart meters, distribution automation systems and other smart grid gear won’t get funding until that critical benchmarking and diagnosis framework is in place.

That means that India could see a much bigger upfront role for the kind of system integration and data analysis work that many U.S. and European utilities are just now starting to add to their multi-million-dollar AMI and DA deployments Those projects are already underway. In January, India’s Ministry of Power named fourteen smart grid projects, combining smart meter deployments and implementation of outage management and peak load management (i.e. demand response), as being eligible for $100 million in funding. Earlier this month, one of these projects, a 1,400-meter deployment in the state of Puducherry, was giventhe go-ahead to expand to 87,000 meters.

OVERVIEW OF SMART GRID TECHNOLOGY* Detect and address emerging problems before they impact service; * Respond to local and system wide inputs and know much more without broader system problems * Incorporate extensive measurements,rapid communications and feedback controls that quickly return the system to a stable state after interruptions or disturbances;

* Automatically adapt protective systems to accommodate changing system conditions; * Reroute power flows,change load patterns,improve voltage profiles and take other corrective steps within seconds of detecting a problem; * Enable loads and distributed resources to participate in operations;

* Be a grid that is self–healing and adaptive,interact healing and adaptive,interactive with consumers and markets, more secure from attacks, accommodate all generation and storage options,accommodate bidirectional energy flow for net metering and predictive rather than just reacting to emergencies.

IMPLEMENTATION OF SMART GRID TECHNOLOGYThe smart grid has a lot to do with decentralization i.e distributed generation and storage,distribution system automation and optimization,customer involvement and interaction,plug in hybrid electric vehicles (PHEV) and even micro grids.That means that it will be necessary to have more intelligence and control beyond generation and transmission throughout the distribution grid and all the way to the retail consumer’s side of the meter.

This will involve few fixed devices like : Supervisory control and data acquisition (SCADA) devices and distribution automation (DA) devices; Automatic meter reading (AMR) devices and smart meters; Retail premises monitoring and control systems and energy management systems (EMS) and Emerging technologies for monitoring and control,both for electric utilities and for consumers. The Uttar GujratVij Company Ltd (UGVCL) will roll out India’s first modernized electrical grid, or the smart grid, in Naroda and Deesa in north Gujarat by April 2014. The process of inviting tenders for the project will begin on December 17 and after a month of evaluation the companies will be selected.
