Technology and Science, Gwalior.
RE
Based Smart Energy Management System utilises 2 of the most popular Renewable
energy sources that are Wind energy and Solar energy for renewable electricity
production. This system is focussed to make users learn about different ways of
electricity production using renewable energy sources. Renewable energy systems
can be categorised into three different categories.
1. Standalone systems:
A
standalone renewable energy system is capable of generating electricity by
itself and does not depend on any external source of electricity. The advantage
of these systems are they can be remotely installed where no other source of
electricity is available. With this big advantage there also comes a
disadvantage that if the system is not in use and the loads are unable to
consume the electricity produced by standalone systems, the power produced is
wasted.
2. Grid Connected Systems
To
resolve the disadvantage of standalone systems Grid connected systems are
developed which transfers the extra unutilised power produced by the system to
national grid. But as the name suggests these systems are grid depended systems
and if due to any reason electrical grid fails, these systems are unable to
produce electricity.
Other Systems
b)
Weather Station
Weather
Station unit includes a pyranometer to measure solar irradiation, a humidity
and temperature sensor to measure ambient humidity and temperature and a Wind
speed and wind direction sensor to measure speed and direction of wind. This
weather station gives an accurate ambient weather data of installed location. A
user will be able to see and program the upper and lower limits of weather data
to ensure safety of the renewable sources and power evacuation units.
c)
Power evacuation units (includes Standalone, Grid connected and Hybrid Systems)
As
explained above these systems are used to extract the generated power using any
of the three systems. A user can select to operate the systems using any of the
method and evaluate the most efficient system for his/her location.
d)
Central Control Unit
The
central control unit allows a user to connect/disconnect any of the power
evacuation mode and control the overall functioning of the system. The central
control unit comes with a software setup to control the system manually or remotely
whichever way is preferred by user.
e)
Load Unit (includes Smart Homes and Load Analysis Kit)
Load
units include Smart homes and Load Analysis kit.
Our Smart House
is a miniaturized model of a Smart home which operates on conventional AC power
supply. It has a relay-based operation which can be operated using c-RIO
connected with PC. There are two AC supplies given with the smart home which
get activated when relay of that particular Smart House is activated from
c-RIO. User can plug in any kind of load to those supplies or user can plug
Load analysis kit there. A multifunction touch screen panel meter is connected
to each of the Smart Houses which measures all the electrical parameters of the
connected load and also displays current and voltage waveforms. All these data
can also be viewed in the provided software using RS485 protocol.
f)Load Analysis Kit:
Generally,
in any home loads are connected in parallel to the AC Mains because in parallel
circuit voltage remains same and current is different as drawn by the load but
in contradiction to that if loads are connected in series, same current will
flow throughout the circuit and every load will have different voltage.
This
load analysis kit demonstrates the same.
Utility of System
This system can be utilized by the user to
perform the following experiments:
1. Setup a solar pv standalone system and calculate
power in different branches of the system
a) calculate efficiency of charge controller
and inverter
b) calculate charge controller efficiency at
different loading conditions
c) calculate inverter efficiency at different
loading condition of inverter.
2. Setup a solar pv grid connected system and
calculate power in different branches of the system
3. Setup a solar pv power plant with the help
of hybrid inverter.
4. Setup a wind energy standalone system and
calculate power in different branches of the system
5. Setup solar pv-wind hybrid standalone system
and calculate power in different branches of the system.
6. Comparing the different types of grid
connected systems and analyzing their waveforms with the help of nonlinear
loads
7. Utilizing smart house as a load and
analyzing load waveforms.
8. Utilizing load analysis kit and
understanding series and parallel circuits.
Masters Training Conducted
Ecosense also conducted a masters training program at MITS. This Masters training program was focused on educating and training the professors, scholars and technicians in Renewable Energy Technology who will further train thousands of students and professionals to start their career or business in this very field.
Program Outcomes
The faculty members and students really enjoyed our two-day training programme
and loved to work on our lab equipment. Professors will conduct experiments on
the system to understand it more deeply and incorporate this lab set up as part
of their regular curriculum.
