Through intelligent adjusting of the (active and) reactive power exchange with the grid, the distributed, grid-connected power electronics in a LV power system may contribute to the (local) voltage regulation in the LV power grid. Even the contributions by the individual units are minor, the aggregated impact from a large number of units could be significant. But, as the contributions from the individual units are minor, the implementation of the contribution to the local voltage regulation from the individual unit has to be cheap.

One way to keep the implementation costs low is to avoid the need for (dedicated) external communication to the units. Autonomous contribution to the (local) voltage regulation may be based solely on the local voltage and frequency. The two main challenges related to this are: 1) to optimise (in terms of i) regulation of the voltage in the entire grid and ii) power losses in the grid) the contributions from the individual units; and 2) to make the regulation of the voltage in the grid smooth, stable and robust.

The Master Thesis is expected to develop and experimentally test strategies for optimised distributed autonomous contributions to a smooth, stable and robust voltage regulation in a LV grid with distributed solar power generation, by autonomous regulation of the reactive power from the individual PV inverters, solely based on the local voltages (and frequency). The experimental verification is expected to be made at the DTU experimental research power system facility SYSLAB, including three distributed PV installations.
