Integration of renewable energy generators into rural distribution networks can cause significant problems with voltage rise at the point of connection during times of maximum generation. One such case is the Denmark Community Windfarm, where the rated power of the wind farm has been limited to 90% in order to keep network voltages within acceptable limits. Expansion of the wind farm is forecast by the wind farm operator due to the location’s good wind resource, and therefore overcoming this restriction is required.

A generation analysis has determined that the wind farm does not currently lose much annual production due to the imposed maximum power limit. However, the implementation of an additional wind turbine generator results in substantial impact on the wind farm’s annual production. A battery energy storage system can limit the amount of wasted generation from the expanded wind farm, but such systems are expensive for utility-scale utilisation and so are not yet economically feasible to implement.

Modern wind turbine generator technology can provide dynamic reactive power support to the distribution network. Application of such machines allows the wind farm to generate at its full potential whilst keeping network voltages within acceptable limits. This is confirmed through simulation of the Denmark distribution network.
