Explore how a virtual power plant integrates gas turbines to regulate power and voltage for wind farms, enhancing grid stability and enabling increased wind power integration, regardless of their physical locations. A model using dq axis reference frame ensures accurate simulation, with fault conditions maintaining wind farm connectivity.
E N D
'Virtual' Power Plant • Gas turbine used regulate power and voltage at point J. • Voltage support allows wind farm to remain connected during a fault. • Regulated voltage and power could allow increased penetration of wind power into grid. • Gas turbine and wind farm do not have to be located in same place. -could offer support to offshore wind farms.
Model • Model uses dq axis reference frame. • Wind farm model stastistically scaled version of validated single wind turbine model. • 3-phase line to earth fault modeled between point J and the grid. Results Normal operating conditions - Voltage regulated to ± 2.5% - Real power regulated to ± 5% Fault conditions - Wind farm remains connected.
