Demand Side Management

analysis of demand side management in tneb ABSTRACT This typography introduces the concepts of posit 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 losings in TNEB. This explains various methods adopted for Energy Conservation in various sectors and helps to foresee 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 efficacious tools for improving qualification efficiency and promoting susceptibility 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. directly A DAYS IN TNEB The Demand-11000mw Available-9000 mw Shortage-2000 mw The chronic power shortages wipe out resulted in involuntary load shedding and interruptions. CONCEPT OF DSMDSM comprises all planning implementing, and supervise activities and measures knowing to improve efficient useto energy and encourage consumers to modify their level and pattern of energy use. DSM involves ?Using existing energy more efficiently. ?Reduction ofTotal quantity of energy consumed by uses through better load managements. ?Minimising losses in the Distribution network. ?Technology substitution. ?Shift demand from peak to dispatch peak times. ?Enhancing energy efficiency. The TNEB build ample motivation to pursue demand management to the extent that it can. ? emend service Increase revenue ? Decrease cost BENEFITS OF DSM Customer Lower bills collect to lower tariff. SocietyCapital freed for other projects. UtilityLower cost of s ervice reduced cost of power. DSM TECHNIQUES The three concern of DSM Techniques are now a days adopted in TNEB ?Load curve modification ?TOD meters. ?Three shift act and staggered off day. LOAD CURVE MODIFICATION 1. treetop 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 consumers energy habits and cost be established.Sector wise electricity ingestions in Tamilnadu efficiency CONSERVATION IN DOMESTIC ?Use only energy efficient (star rating) Appliances. ?Use only wires and appliances that have I. S. I. mark. ?Wiring must be carried out only by the licensed electricians. ?Do not use flexible wires for long distance. ?Maintain meetly the galvanizing appliances and wiring. ?Use compact fluorescent lamps (CFL) instead of ordinary bulbs . It gives greater light and reduced the consumptions 5 times. ?Economy in the use of water will reduces the consumption of electricity. Provide Electronic ballasts to the tube lights. ?Provide Electronic regulators to the fans. ?Use micro wave ovens heater for cooking purpose. ?Avoid open the refrigerator door frequently. gaint put hot things in to the refrigerator. ?Use voltage stabilizers for the electrical equipments. ?Dont use the power loads during peak hours. ?Switch off the lights & fans while leaving the room or house. ?Avoid using decorative lamps. ?Avoid switching on the water heater in the previous dark for the requirement of hot water in the next early morning. ?Utilise sun-lights for the maximum extend.A well planned house with number of windows and good ventilation system reduces the energy consumption. ENERGY CONSERVATION IN INDUSTRIES Dont use motors of higher capacity than required. Use required I. S. I shut connectors separately for apiece motors to maintain power factors. Maintain the machines and appliances properly and regularly. Change the worn-out bearings and avoid wearing out due to friction. Ensure that the motor belts are in proper tight. Use different motors using instead of single high horse power motor for different purposes. Use high efficiency pumps and blowers. If monthly consumption exceeds 10,000 units energy audit is necessary. Periodically modernize the appliances is essential. ENERGY CONSERVATION IN AGRICULTURE ?Replacement of inefficient agricultural pumps by newly Developed energy efficient pump set. ?Adopt water conservation principles. ?Provide shunt capacitors to the motors. ?Avoid unnecessary additional loads. ?Use P. V. C. pipes instead of steel pipes. ?Avoid flex and leaks in the pipes. ?Dont operate the motors in two phase. ?Dont use the low power factor rewound motors. ENERGY AUDITIt is verification, monitoring and analysis of use of energy including submission of a technical reports containing recommen dations for improving energy efficiency with cost benefit reduce energy consumption. CONCEPT OF ENERGY AUDIT ?Determine how and where energy is being used or converted in to one form to another. ?Identify opportunities to reduce energy usage and prevent energy losses. Energy Auditing involves ?Identifying energy losses. ?Segregating the losses into technical and commercial losses. ?Estimating the energy conservation potential of a system. Save Energy Save Nation
