Comparison between the two equivalent methods of collector system for wind farms

Aggregation modelling of wind farm includes equivalence of wind turbines and simplification of the collector system. Collector network is a significant part of the wind farm. Equivalent method of collector system is very important to the quality and the effectiveness of equivalent model for wind farms. As such, two different equivalent methods of collector system are studied. They are voltage-based method and power consumption-based method. Two equivalent models are built using the above methods. A comparative analysis of the two methods is carried out by comparing with detailed model of wind farm. The simulation results show that voltage-based method is better than power consumption-based method.
