Abstract [en]

This report describes the need for aggregation of wind farms due to the recent penetration of wind power generation in the power system and the methodology to simplify a distribution network consisting of a number of wind turbines equipped with induction or synchronous generators and MV lines. This methodology leads to an equivalent network which consists of an approximate equivalent wind turbine or groups of wind turbines and an approximate equivalent line or lines. The aim of the methodology is to reduce the complexity of the system and also the simulation time. Simulations are performed using a simulation software package PowerFactory supplied by DIgSilent, which is a tool for short term and long term dynamic analysis. The validation of the methodology and models used are examined by applying different layouts and considerations. The response of both detailed and aggregated models, under the same contingencies are compared. The influence of wind conditions such as wind speed and wind direction, is also considered. The project consists of two main parts. The scope of the first part is to validate an aggregation methodology with DIgSilent PowerFactory Software. The second part aims to verify a wind park aggregation considering the wake effect. In both cases the simulation time improvement is shown.
