identify is a system which makes use of

identify and analyse the possible energy saving
options in an allotted time frame. A detailed information about the energy
consumption patterns and wasted energy in the facility was obtained from this
energy audit. With the help this data produced, many options available for
energy conservation and cost optimization were identified.

Energy Management System (EMS) is
a system which makes use of computer-assisted tools/software for monitoring,
controlling and optimizing the performance of the generation, transmission and
load system. The computer technology used is also known as EMS/SCADA. EMS
mainly improves the efficient use of electricity, contributes towards
conservation of energy resources and indirectly reduces the emission of
greenhouse gases14.

 

Demand-side load management with
the help of digital information communication systems and smart meters results
in optimization of Energy consumed. Energy Management System subsists of
monitoring, measurement, load forecasting, planning, implementing and
verification of electrical energy demand which are intended for consumers to be
aware of the electricity usage and dynamic pricing is achieved. The energy
management system will also include the capability of monitoring theft circuits
in each room to ensure that appliances such as televisions aren’t
disconnected9. Devices such as fans and lights are subjected to continuous
load operations, which results in drastic shortening of efficiency. The energy
management system should be capable of monitoring and be controlling these
devices in aggregation with cooling appliances. Air conditioners often operate
at reduced efficiency due to ice build-ups which inhibit their heat transfer
capability. The capability of periodically cycling air conditioners to prevent
reductions in efficiency due to ice build-ups would be a desirable capability
of the energy management system. Energy costs are higher during peak load
periods than normal load periods. In order to exuviate the load during peak
load periods a load stabilizing technique is incorporated into the system,
which limits the overall energy demand. This model ensures that the available
energy is shared among all the devices based on their priority, especially
during the peak-load situation.

 

The presented model in this paper
can be erected via wired communication and also wireless communication. Wired
communication requires various specially-designed cables for interconnecting
the smart meters, plugs and various other monitoring devices16. But Wireless
communication model is cost effective and requires no cables. Load forecast,
weather forecast, load measurements and indoor temperature measurements are
also taken into account for efficient optimization5.

The power charges in common
areas are automatically calculated and distributed between the consumers based
on per floor area. The data entry consists of No. of slabs, Slab rates
