Web-based online real time reliability information system for composite power systems including wind turbine generators

This paper proposes a new methodology for evaluating the probabilistic reliability of a grid constrained composite power system including wind turbine generators (WTG). The proposed model can consider capacity limitations and transmission line unavailability. The importance of renewable energy sources has been growing at a rapid rate due to environmental concerns. In particular, wind energy is one of the most successfully utilized such source to produce electrical energy. The random nature of wind speed can be incorporated in the evaluation by representing the WTG by multi-state models. A web based online real-time reliability integrated information system (WORRIS) has been developed using the methodology proposed in this paper. This paper describes the architecture of the WORRIS Version 1.0 system developed preliminarily in this study. It is intended to extend the initial version to create one day ahead of reliability information system.
