The Power Grid Operation Cockpit (POC) is the top-level application and user portal for the power grid dispatching and control system. Centered on Key Performance Indicators (KPIs) of grid operation, it provides users with KPI monitoring, early warning, information mining, decision analysis, and control functions by aggregating and extracting various grid operation information, invoking relevant calculation and analysis services, and centralizing various operational and control functions. It offers operators a comprehensive, intuitive, and closed-loop environment for managing the power grid.
