Control development and modelling for flexible DC grids in Modelica

Electrical power consumption is ever increasing and production by local renewable sources is also increasing. In practice, this means that power distribution networks needs to be able to handle more power flux scenarios than before. Such flexible power grids, “Smart grids”, have several units coupled together and need to be intelligently controlled to keep desired voltage level. The control is performed by converters, both AC and DC, which are fast enough to provide controllability.
