-Power system risk assessment methodologies and case studies to introduce a new can be used for power system planning, design, operation and maintenance of the field of risk assessment approach. The approach emphasizes engineering applications to explore the practical problems of the power system. According to the different requirements of the planning, operation, maintenance and asset management, development of specific concepts, and the targeted approach and implementation steps, such as component aging failure model, the outage model and a new concept common cause outage separation models and components group . Instance of the power system expansion planning of Canadian cities shows how the reliability of the probability of a specific project assessment, in order to achieve the optimal allocation of resources, so that the system risk is maintained at the target level.
