Dynamic analysis of wind power integration into the Northern Interconnected Power System of Chile

Energy policy of Chile establishes that by 2025, at least 20% of the annually generated energy must come from renewable energy sources. In this context, many projects of solar and wind farms have been presented for connection in ten Chilean electrical systems. The aim of this study is to evaluate the transient behavior of the Northern Interconnected System (SING) regarding the high levels of integration of wind generation. The behavior of the most important wind farms under construction and / or approved for construction is analyzed. A comparative study of the technologies of fixed speed, doubly fed and full converter is carried out in two points of the system employing software for electrical system analysis, DigSILENT. The main results show that technologies of fixed speed and doubly fed have a better response in the voltage and reactive power variables, meanwhile the angle and reactive power performs better in a full converter technology.
