First steps in DC home- grid power management

A demonstration setup of the Tesla Powerwall has been installed by Eneco at the department of DCE&S at the TU Delft. This setup is used to investigate the functionalities of the Tesla Powerwall. As research is being done about transforming AC homegrids towards DC homegrids, it would be interesting to investigate how the Tesla Powerwall would function in these surroundings. A lot of research has already been done about DC-microgrids, however a design containing the Tesla Powerwall is missing. In this thesis the first steps for the design of a DC homegrid model containing loads, generation and storage have been made. A configuration of buck and boost converters are made for transformations between the different voltage levels. Simulations in Simulink have shown that the chosen topology produce the desired voltage levels. The model can be used for further analysis of the DC homegrid. M.L. Gravemaker 4117352 S.
