Voltage control on the transmission grid using wind power at other voltage levels

In a power system there is a need to keep a good voltage. This is often done by using the synchronous generators in the power plants connected to the transmission system. With large amounts of solar and wind power enters the system, then the amount of these centrally power plants will decrease. The question is then how to keep the voltage.
The volatile project is to use wind power stations on other voltage levels to keep the volt-age on the transmission level. Methods concerning controller design, communication and parameter setting will be combined with impact studies on real networks in order to estimate the possibility to implement this option.

The project results consist of OPF algorithm of power systems with hybrid AC/DC grids and wind power, coordinated voltage control of wind power plant with HVDC connection, and evaluation of coordinated var/volt control of the Kriegers Flak project.
