IIT Dharwad is one of the new IIT’s putting a
great effort towards research in the field of Microgrids and Energy Storage.
Ecosense installed a "Grid Connected
Battery Energy Storage System" at the Indian Institute of Technology (IIT)
Dharwad in Karnataka to support experiments and research in sustainable energy
systems.
The system has been designed to store excess
power generated by any of the sources and store it in the battery bank which
can be used later when needed by the grid or the load connected at the point of
common coupling. This is purely research-based system which can be customised
by the client as per his/her research requirements.
In this system a Lithium-ion battery bank is
connected with a bidirectional converter which further connects to a common DC
Link. The DC Link is further connected with a three-phase grid connected
inverter. The system is software controlled and client is provided with open-source
software to edit any of the control algorithm.
The program allows a
user to charge battery bank from grid as well as discharge into the grid. The
system can also be operated in standalone mode with load connected at the
three-phase output.
The open-ended DC
Link terminal allows user to connect any of the sources via a DC-DC converter
of compatible ratings which gives an extra edge to the research scholars as
they can explore the system using various sources and conduct their research.
• Ability to control DC link voltage using bidirectional converter in
stand-alone mode
• Research
on Microgrid possible as the DC link can accommodate other renewable sources
such as PV
• Power
flow and quality supplied to the grid can be controlled and analysed
• Further
exploration of control techniques for smart grid implementation possible
•
Continuous sensing of grid side voltage and currents provide opportunity to
implement advanced control algorithms to control the behaviour as per grid
conditions
• Maintaining
minimum reactive power at inverter output to achieve unity power factor and
maximize the usable power generation
Ecosense’s BESS enables user to do research in the field of Microgrid management, load side management, priority allocation to renewable sources etc. Ecosense’s BESS is an open-source system where a user can reprogram, rewire, and revise the system to carry out their research goals. All the sources are independent of each other and research can also be carried out on each of the sources independently. Ecosense provides source file based on LabVIEW platform which can be easily modified as per the user’s liking. Ecosense appreciates and also provide an active support to users carrying out their research.
