analysis of demand side management in tneb
This paper introduces the concepts of Demand Side Management(DSM) and various areas it involves. The interest and necessary of DSM in TNEB is explained in the context of a number of much wider developments in power sector. It present a framework for DSM Techniques and factors to reducing T&D losses in TNEB. This explains various methods adopted for Energy Conservation in various sectors and helps to prevent global warming.
Demand Side management is the process through which a power utility manages the demand for power among all its Customers to meet its current or future needs..
DSM is an effective tools for improving energy efficiency and promoting energy conservation. The problems of the Indian power sector including TNEB traced to three root issues.
1.High T & D Losses.
2.Large commercial losses (Metering, Billing, Collection)
3.Low end - used efficiency of energy use.
In TNEB it facing peak Power capacity shortages as well as the energy shortages.
NOW A DAYS IN TNEB
The chronic power shortages have resulted in involuntary load shedding and interruptions.
CONCEPT OF DSM
DSM comprises all planning implementing, and monitoring activities and measures designed to improve efficient useto energy and encourage consumers to modify their level and pattern of energy use.
Using existing energy more efficiently.
Reduction ofTotal quantity of energy consumed by uses through better load managements.
← Adoption of Energy conservation techniques.
Minimising losses in the Distribution network.
Shift demand from peak to off peak times.
Enhancing energy efficiency.
The TNEB have ample motivation to pursue demand management to the extent that it can.
❖ Improve service
❖ Increase revenue
❖ Decrease cost
BENEFITS OF DSM
Lower bills due to lower tariff.
Capital freed for other projects.
Lower cost of service reduced cost of
The three concern of DSM Techniques are now a days adopted in TNEB
Load curve modification
Three shift operation and staggered off day.
LOAD CURVE MODIFICATION
System peak load reduction at specific
Building the load during off peak
Modification of the load shape through
Balance of load so that demand from
different users peaks at different times.
Shifting load from on peak to off peak periods
Installation of Time of day (TOD) Electronic meters would help in flattering the load curve by way of giving incentives / penalties to consumers during off peak / peak hours respectively. Now above 25 HP industrial services are provided TOD meters in TNEB.
Three shift operation and staggered off day
Encourage the industrial consumers for three shift operation and staggered off days to reduce the demands.
REDUCTION OF T & D LOSSES
Now the T & D losses in TENB is around 18% it should be reduced with in 10% of the standard.
The factors reducing T & D Losses are
Strengthening of Conductors.
Erection of Transformers at load center.
Improve joints and connections.
Laying Additional Linklines.
7. Increases HT : LT Ratio.
8. Proper Maintenance of Distribution Network.
DSM FOR CONSUMERS
DSM on the consumer side requires that a system of collection, analysis, and reporting on the consumer’s energy consumptions and cost be...
