A smart city is defined as a city equipped with intelligent infrastructure which provides improved quality of life with sustainable environment through smart built solutions. Smart cities demand for a reliable, energy efficient and quality power and thus smart grid becomes imperative.<\/p>\n

The smart grid technologies which are deployed in smart cites include
\n– Distributed Generation
\n– Distribution system Automation
\n– Smart Homes
\n– Advanced metering infrastructure
\n– Energy Storage and grid integration
\n– Electric Vehicles and grid integration<\/p>\n

Distributed Generation<\/strong>: Distributed generation sources include solar, wind, biomass and fuel cells which are closer to the end users. Distributed generation being close to the end users, it reduces the cost of transmission and distribution. Other benefits include modularity & flexibility, energy efficiency and emission reduction. In a smart city it will be possible that consumers having their own renewable generation source to sell the excess generation back to the utility. This will help utilities to manage the peak demand and reduce the need for building new high-voltage transmission lines.<\/p>\n

Distribution System Automation<\/strong> enables real time monitoring and control of entire distribution system to maintain stability in the grid through centralised Master control centre. Distribution automation system (DAS) includes substation automation system, feeder level automation and customer level automation. Some of the DAS applications relevant to smart cities are outage time management system, voltage regulation, fault isolation and sectionalisation, load management, demand side management.,etc.<\/p>\n

Smart Home<\/strong> – Smart home is equipped with smart and intelligent appliances which can communicate with each other such that day to day household activities are automated without much manual intervention. They also enable remote control and monitoring of the appliances from anywhere using mobile phone or any other internet connected device.
\nSome of the features of a smart home are
\nLighting: Automatic light control based on a time cycle or based on occupancy sensor, brightness control, remote control of lights through Wifi or internet.<\/p>\n

HVAC: Remote control of the building’s heating and air conditioning systems through Internet-controlled thermostat.<\/p>\n

Audio Visual: Selection of audio\/video to every\/any room as per user\u2019s choice, remote control through mobile phone, music linked with lighting to provide mood setting. etc<\/p>\n

Security system integrated with home automation system provides remote surveillance of
\nsecurity cameras, central locking of all perimeter doors and windows, detection of
\nunauthorized movement through motion sensors and notification alert to the users via cell
\nphone.<\/p>\n

A typical smart home system features is illustrated in the diagram below.<\/p>\n

Advanced metering infrastructure<\/strong> (AMI) enables two way communication between utilities
\nand consumers through integration of smart meters and communication networks. Accurate
\nmeasurement, automatic identification of unmetered connections, instant alarm in case of
\nmeter tamper detection, reduced line losses due to reduced maximum demand are some of
\nthe features of AMI in smart cities.<\/p>\n

Energy Storage<\/strong>: Renewable energy coupled with energy storage can provide reliable and
\nquality power to smart city. The surplus energy that is generated from renewable sources,
\nsuch as solar or wind is stored and used later when the demand is high thus reducing the
\nmaximum demand of the smart city…Battery energy storage is well proven and would be the
\nmost suitable technology for smart cities due to its easy integration. Some of the applications
\nrelevant to Smart cities are peak shaving, renewable energy time shift, grid regulation and
\nmicro grid.<\/p>\n

Electric Vehicle<\/strong> – Electric Vehicle (EV) derives all or part of the energy required from
\nelectric grid with electrical energy stored in battery for propulsion. Some of key merits of
\nEVs are simple construction, low maintenance, no emission and thus protects environment,
\nlow noise and more efficient.
\nGovernment of India\u2019s goal is to achieve 30% EV by 2030. In Smart cities, smart
\ntransportation with reduced emission is one of the key objectives to be met. Thus
\nelectrification of personal vehicles, fleet and public transport is essential and many initiatives
\nare in progress such as conversion of public transportation to electric vehicles, building
\ncharging infrastructure, deploying E auto-rikshaws, etc<\/p>\n

TCE is executing a number of smart city projects offering various services including
\npreparation of feasibility study and DPR, basic engineering, detailed engineering,
\nspecification preparation, support services for tendering and contract award, review
\nengineering , project management & coordination, inspection & expediting, construction
\nsupervision and commissioning support.<\/p>\n","protected":false},"excerpt":{"rendered":"
