Stability enhancement of a power system with wind generation & STATCOM

Recent trends of opening electricity markets to competition worldwide and introducing new forms of generations, especially from renewable resources, are putting increasing amounts of stresses on the existing systems. The general objective of this research is to study the impact of Distributed Generation (DG) on the stability of a power system. The DG to be considered is Wind Energy Conversion System (WECS). Proposed solutions in order to minimize the impact of WECS presence within an electrical power system are investigated. Some of them include the utilization of STATCOM in order to regulate induction generator´s terminal voltage and Power System Stabilizers (PSS) for damping of synchronous generators oscillations. The design of PSS and STATCOM parameters are considered as an optimization problem and Genetic Algorithms (GA) are used for searching the optimized parameters. The results show the effectiveness of the proposed design approach.
