JAMMU, Mar 23: For vitalizing the power distribution system with technical advancements for reliable smart grids in smart cities, the Powergrid Corporation of India suggested some measures.
The government of India initiated awareness programmes to ensure energy supply reaches every house hold. Significant technological changes ensued, in the India network sub transmission involves a ring main system but far ends only have radical connections leading to low voltage and increased transmission losses. In the current scenario with about 100 Cities declared as Smart Cities, a high quality electric power supply is crucial for maintaining smart grid systems and ensuring security monitoring.
To meet the requirements of a smart city in supporting a sustainable high-quality lifestyle for people, there is a need of a lot of smart technologies & a smart city needs a smart grid.
Smart grid is an integration of electrical and digital technologies, information and communication. It delivers electrical power to the customers using two-way digital technologies and also monitors the supply to the customers and measurements.
Existing grid has the limited delivery system and a high cost of a power outage and power quality interruption and the communications of the grid are too slow.
The smart cities of today will require a network which can enhance the system reliability by adapting new technologies. It also provide end to end efficient power management. This includes high level utility strategic planning functions. The existing power network is outdated and needs better systems to achieve improved, reliable and economical power delivery information flow and secure integrated communication.
The Smart Grid with digital communications help to keep an eye on the network whether it is working properly or not, if in case any fault is detected in the network it is capable of sorting it and removing it and again restoring it to maintain the continuity of the system. This action is called as the self healing action.
A Smart Grid is an electrical network that in integration of digital and other technologies to monitor the transfer of electricity from various generating stations to fulfill the demand for the users. It uses smart appliances like smart meters for monitoring, smart energy storing devices, regulating devices for power quality monitoring etc.
The smart grid has advantages for all the consumers whether domestic, industrial or commercial. It simply provides two way channel for energy transfer as it can communicate with both the conventional grids and non conventional grids.
Smart city schemes to be approved along with deployment of VAR compensators to avoid fluctuation and disturbances etc.
Compensators need to be installed at sub transmission level. Smart Grid strongly require such controllers for smooth functioning.
While approving schemes system requirement need to be reviewed from all angles.
To achieve improvement in supply at tail end there is need for deployment of ETOS, Use of capacitors at Load Point and using HTL conductors in Sub transmission suggest Powergrid.
