Characteristic Evaluation of Wind Power Distributed Generation Sizing in Distribution System

Energy consumption and environmental issues have become major drivers of increasing renewable energy penetration levels. The electricity generated from sources is decentralized throughout distributed generation (DG), which located at the distribution level. However, presence DG can change system characteristics affect protection systems. Thus, this study aims to investigate impact in term its sizing placement on systems under both normal fault conditions. In addition, effects voltage improvement conditions current are also considered. case was modelled after an actual section a 22 kV line Provincial Electricity Authority Thailand using PSCAD software. For DG, wind turbine selected as source. simulation results demonstrated that has significant These impacts caused by operation conventional systems, require further analysis preventive measures order ensure good reliability.
