| Sumario: | It is evident that the world will soon run out of fossil fuels and renewable energy sources
such as solar power and wind power are getting utilised more and more in hopes to replace
fossil fuels. With the help of DC microgrids, it is very possible to provide supply to
consumers’ demand with renewable energy sources. In a DC microgrid, one of the most
important feature it has is the battery and the purpose of having a battery is to help with
the supply and demand of the whole microgrid. To help integrate the battery into a DC
microgrid, a DC/DC converter is needed. In this Final Year Project, the author would be
developing a DC/DC converter for a Vanadium Redox Battery (VRB) that is commonly
used in a DC microgrid. A DC/DC boost converter is built and by introducing control
methods such as proportional-integral (PI) control, better control of the converter can be
exercised to improve the efficiency of the converter. Implementations are also introduced
during the project to further the author’s understanding on DC microgrid. Super-capacitor
is another type of energy storage system that has characteristics as compared to a battery.
Hence, droop control is introduced to ensure that the energy storage systems can be
integrated properly so that maximum efficiency can be achieved.
