Study on the maximum active power and the maximum distance of the transmission line for the renewable energy station

Reasonable determination of the maximum transmission active power and maximum transmission distance of the transmission line is essential for guiding the design and site selection for renewable energy stations. Based on the characteristics of changes of the operating conditions of renewable energy stations, this paper studies on the effects of static power angle stability, line voltage drop, capacity rise effect, and cable capacitor charging on the maximum transmission active power and maximum transmission distance of the output line. The method to calculate maximum transmission active power and maximum transmission distance for output line is developed. The maximum transmission active power of the output line and the maximum transmission distance are inversely related. By rationally adjusting the planned capacity or the transmission distance of the new energy power station, it can ensure that the electric energy of the new energy power station is effectively consumed.
