analysis of demand side management in tneb

ABSTRACT

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.

DSM

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 Demand-11000mw

Available-9000 mw

Shortage-2000 mw

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.

DSM involves

ΦUsing existing energy more efficiently.

ΦReduction ofTotal quantity of energy consumed by uses through better load managements.

← Adoption of Energy conservation techniques.

ΦMinimising losses in the Distribution network.

ΦTechnology substitution.

ΦShift demand from peak to off peak times.

ΦEnhancing 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

Customer : Lower bills due to lower tariff.

Society:Capital freed for other projects.

Utility:Lower cost of service reduced cost of
power.

DSM TECHNIQUES

The three concern of DSM Techniques are now a days adopted in TNEB

ωLoad curve modification

ωTOD meters.

ωThree shift operation and staggered off day.

LOAD CURVE MODIFICATION

1.Peak clipping-System peak load reduction at specific
periods.

2.Valley filling-Building the load during off peak
hours.

3.Conservation-Modification of the load shape through
conservation.

4.Load building-Balance of load so that demand from
different users peaks at different times.

5.Load shifting-Shifting load from on peak to off peak periods

TOD METERS

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

1.Network Reconfiguration.

2.Strengthening of Conductors.

3.Erection of Transformers at load center.

4.Load Balancing.

5.Improve joints and connections.

6.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...
