This newspaper first gives a short idea about Usage of Solar & other Alternate Energy Resources for smart grid. This paper first gives a concept behind grid & smart grid. It also includes characteristics of smart grid, history of smart grid, smart grid function & types of technology used for smart grid. In addition, it includes idea about smart energy meters, furthermore it also shows about governmental procedures regarding smart meter. This newspaper also gives a quick idea regarding future scope of smart grid in India. Which shows why India needs smart grid? It also includes goal, opportunity & advantages of smart grid over normal grid.
An energy grid that uses advance digital technologies, that will improve the energy consistency, save energy and cost, and will allow increased consumer participation. The grid changes from its present centralized model to decentralized model in which consumer can be energy recipient, supplier, and maker. Smart Grid is an umbrella term, which can be used for mixture of technologies, solutions, and processes. Matching to Division of Energy (DOE), USA, the grid will have following characteristics: -
"Informed, engaged, and active consumers - demand response and sent out energy resources. "
"Many allocated energy resources with plug-and-play convenience give attention to renewable"
"Mature, well-integrated inexpensive markets, expansion of new electricity marketplaces for consumers"
"Electricity quality is important with a number of quality/price options - fast resolution of issues"
"Greatly widened data acquisition of grid variables - focus on prevention, lessening impact to consumers"
"Automatically picks up and responds to problems - focus on prevention, reducing impact to consumer"
"Resilient to attack and natural disasters with rapid restoration capacities".
Before examining particular technology, a proposal can be understood in terms of what it is being necessary to do. The governments and utilities financing development of grid modernization have identified the functions necessary for smart grids.
Motivate consumers to positively participate in operations of the grid
Provide higher quality power that helps you to save money lost from outages
Accommodate all era and storage options
Enable electricity market segments to flourish
Run more efficiently
Existing and prepared implementations of smart grids provide a variety of features to perform the required functions.
The total insert connected to the energy grid can vary significantly as time passes. Although the total weight is the total of many individual choices of the clients, the overall fill is not a stable, gradual varying, average power consumption. Visualize the increment of the load if a popular television program starts and millions of televisions will get current instantly. Typically, to respond to a rapid upsurge in power ingestion, faster than the start-up time of a big generator, some extra generators are put on a dissipative standby setting. A good grid may alert all individual television packages, or another greater customer, to lessen the load briefly (to allow time to get started on up a more substantial generator) or continually (in the case of limited resources). Using numerical prediction algorithms it is possible to predict how many standby generators need to be used, to attain a certain inability rate. In the original grid, the failure rate can only be reduced at the expense of more standby generators. In a smart grid, the strain decrease by even a small portion of the customers may get rid of the problem.
Demand response support allows generators and tons to interact in an automated fashion instantly, coordinating demand to flatten spikes. Getting rid of the fraction of demand that occurs in these spikes eliminates the cost of adding reserve generators, slices wear & rip and extends the life span of equipment, and allows users to slice their energy expenses by informing low priority devices to utilize energy only when it is cheapest.
Although multiple routes are touted as an attribute of the smart grid, the old grid also presented multiple routes. Primary electricity lines in the grid were built utilizing a radial model, later connectivity was assured via multiple routes, referred to as a network framework. However, this created a fresh problem: if the existing move or related results over the network exceed the limits of any particular network factor, it could fail, and the existing would be shunted to other network elements, which eventually may are unsuccessful also, leading to a domino effect.
Another factor of problem tolerance of smart grids is decentralized electric power generation. Distributed era allows specific consumers to generate power onsite, using whatever technology method they find appropriate. This allows individual lots to tailor their era right to their fill, making them indie from grid electricity failures. Common grids were made for one-way move of electricity, but if an area sub-network creates more power than it is eating, the reverse stream can raise security and trustworthiness issues. A good grid can deal with these circumstances.
off-peak time the purchase price is reduced significantly, mainly for heating safe-keeping radiators or warmth pumps with a high thermal mass, also for domestic appliances. This idea will be further explored in a good grid, where in fact the price could be changing in moments and electric equipment is given methods to react on that. Also, personal
In many countries, including Belgium, holland and the united kingdom, the electric utilities have installed double electricity meter in many homes to encourage people to use their electric power during night time or weekends, when the overall demand from industry is very low. During tastes of customers, for example to only use green energy, can be contained in that vitality grid.
Above diagram shows the working difference between Normal Grid and Smart Grid.
The bulk of smart grid technology are already used in other applications such as
Manufacturing and Telecommunications and are being modified for use in grid functions. Generally, smart grid technology can be grouped into five key areas:
Some communications are up to date, but are not uniform because they have been developed in an incremental fashion rather than fully integrated. In most cases, data has been accumulated via modem somewhat than immediate network interconnection. Areas for improvement include: substation automation, demand response, circulation automation, supervisory control and data acquisition. energy management systems, wireless mesh sites and other systems, power-line carrier communications, and fiber-optics. Integrated communications permits real-time control, information and data exchange to optimise system reliability, asset utilization, and security.
Core tasks are evaluating congestion and grid balance, monitoring equipment health, energy fraud prevention, and control strategies support. Technology include: advanced microprocessor meters (smart meter) and meter reading equipment, wide-area monitoring systems, vibrant line rating (typically predicated on online readings by allocated temperature sensing coupled with real time thermal rating systems), electromagnetic personal dimension/analysis, time-of-use and real-time prices tools, advanced switches and wires, backscatter radio technology, and digital relays.
A smart grid replaces analog mechanical meters with digital meters that record
Usage in real time. Smart meters act like advanced meters and provide a communication path extending from technology plants to electric outlet stores and other smart grid-enabled devices. By customer option, such devices can turn off during times of peak demand.
High speed sensors called PMUs distributed throughout their network can be used to monitor
Power quality and in some instances reply automatically to them. Phasors are representations of the waveforms of alternating electric current, which preferably in real-time, are identical just about everywhere on the network and comply with the most desirable shape.
With such great deficiencies in basic infrastructure, why would India want to consider buying smart grid technology? In the long run for India to continue along its route of aggressive economical growth, it requires to build a modern, intelligent grid. It is only with a reliable, fiscally secure Smart Grid that India can offer a stable environment for investments in electric infrastructure, a prerequisite to mending the fundamental issues with the grid. Without this, India will not be in a position to keep tempo with the growing electricity needs of its cornerstone sectors, and will fail to create an environment for development of its hi-tech and telecommunications areas.
The Indian National Government, in cooperation with the State Energy Board, put forward a street to improvement when it released the new Electricity Function of 2003, aimed at reforming electricity laws and bringing back overseas investment. The act had several important measures:
Unbundling their state Electricity Board's property into different entities for technology, transmission, and distribution, with the objective of eventual privatization
Adding capacity in support of a projected energy use expansion rate of 12%, coinciding with a GDP progress rate of around 8%
· enhancing metering efficiency
· auditing to build transparency and accountability at their state level
· Advanced billing and collection
· Mandating minimum amount amounts of electricity from renewable
· requiring preferential tariff rates for renewable
· End use efficiency to lessen the price tag on electricity
There has been a recent force in India to start labeling home appliances with energy use to help consumers determine working costs. There has also been significant effort to improve energy efficiency, for example to improve the average energy efficiency of ability plants up from 30% to 40%, and moving major industries to lessen energy ingestion.
. This neglect has accumulated in a number of system failures:
· poorly prepared distribution networks
· overloading of system components
India's grid is looking for major improvements
· Lack of reactive power support and rules services
· Low metering efficiency and expenses collection
· Power robbery while the national government's ambitious "Electric power for all those" plan demands the addition of over 1 TW of additional capacity by 2012, it encounters the task of overcoming a history of poor ability quality, capacity shortfalls and regular blackouts.
From these method discussed, it is high need for any country to visit for green electric power like Solar; Blowing wind Etc. Smart Grid is the right solution for reaching the go up of electricity demand.
