| Abstract |
Technological development in the wind power field is an important challenge for its evolution. Therefore, the development of systems to improve voltage stability,
frequency stability and power quality is an important line of research in the wind power field. In order to promote the integration of wind farms into the electrical network, Flexible AC Transmission Systems, FACTS, are widely used. The FACTS STATCOM system is one of them. Numerous studies have shown that transient and steady state stability can be improved by controlling the voltage of the connection point of the wind farm to the network. The STATCOM system stimulates voltage stability by reactive power regulation. STATCOM provides or absorbs reactive power to or from the grid to compensate voltage variations in the connection point of the wind farm with the grid. In this paper we show various control
strategies for reactive power delivered by a wind farm, which has a STATCOM system. This is considered a 9-bus model network, a wind farm model consists of DFIG generators and a model of STATCOM. Numerous dynamic simulations are showed. |
