Abstract:This study analyzes the changes of the new generation power grid dispatching and control system in architecture, human-computer interaction modes, business organization modes, etc. It sorts out the new business-oriented requirements for authority management and proposes the business-oriented authority management solution with regard to this new system. The key technologies in this system are discussed, such as path-based global controlled resource identification and definition, metadata-based controlled resource management, multi-factor access control based on a rule engine, and cross-domain access control based on upper and lower organizational relationships. This solution is verified in a prototype system and provides a multi-dimensional secure access control method of controlled resources for business scenarios in the new generation power grid dispatching and control system.
