Last week Pedro Parreira graduated from the MSc in Electrical Engineering at TU Delft. During his thesis, he has been working on “Distributed optimal power flow for low voltage DC grids” at DC Opportunities. For the past months, Pedro developed an optimization algorithm for low-voltage DC grids which eliminates the need of a central controller. By utilizing physiscal measurements of the grid, it is now possible to control local voltage and power with the goal of minimizing cost.
