Definition of Smart-Grid The term smart grid defines a self healing network equipped with dynamic optimization technique that use real time measurements to minimize network losses maintain voltage levels increase reliability and minimize network losses, maintain voltage levels, increase reliability and improve asset management. The operational data collected by the smart grid and its subsystems will allow system operators to rapidly identify the best strategy to secure against attacks, vulnerability and so on, caused by best strategy to secure against attacks, vulnerability and so on, caused by various contingencies. 4 Source : Fundamentals of Design & Analysis ( James Momoh ) IEEE

Smart Grid Project to Come Up in Puducherry PUDUCHERRY, MARCH. 2,2012: India's first smart grid project recommended by the Power Ministry's India Smart Grid Task force will come up on a pilot basis in the union territory, an official release said today. The project involves an investment of Rs 77 crore, of which Rs 25 crore would be borne by the Ministry and the balance will be borne by PGCIL & Partners, it said. A Memorandum of Understanding to introduce the innovative project here signed in g p j g the presence of the Chief Minister, Mr. N. Rangasamy, here today between the Department of Electricity and Power Grid Corporation of India Ltd (PGCIL). In Puducherry, the entire share of Rs 52 crore would be borne by PGCIL, a collaborator in the implementation of the project here. The Ministry proposed to set up such smart grid p p j y p p p g projects in twenty one cities across India and that Puducherry is the first to implement it on an experimental basis, the official statement said. 7 Source: The Hindu
