TOD meters
Installation of time of day (TOD) electronic meters and introduction of TOD tariff is a significant DSM technique. This would help in flattening the load curve through way of giving incentive/disincentive to consumers during off peak/peak hours, respectively.
Three-shift Operation and Staggered Off Day
Demand from an industrial customer might be very steady if the company is running a three-shift operation or if the off days could be staggered. We should discuss some DSM measures for industrial customers in the next unit.
Further, energy audit of the power system is undertaken as a part of DSM to pinpoint excessive loss prone areas. Reduction of T&D losses in LT distribution system can be done through installation of amorphous core distribution transformers (AMDTS), and installation of LT switched capacitors for improvement in voltage level and power sector. Table reveals the advantages of using high efficiency distribution transformers over conventional transformers, by the initial costs might be higher.
