Technology of Cross System User Access Control in New Generation Power Grid Dispatching and Control System
This article analyzes the changes of the new generation power grid dispatching control system in system architecture, clarifies the requirements of cross system user access control, elaborates authorization strategy based on dual subject of user and dispatching agency, token-based cross system access control strategy, cross identity authentication center token verification and caching strategy. Finally verified the feasibility of the solution based on the environment of the new generation power grid dispatching control system at dispatching agency of East China, Jiangsu and Shanghai.
