It consolidates traditionally separate business applications—such as dispatching, centralized control, distribution, relay protection, and security automation—into a single system. Concurrently, it facilitates vertical connection across dispatching control centers at all levels as well as plants and substations, enabling the sharing and coordination of information for planning, data management, analysis, and control in dispatching operations. It serves as a comprehensive solution for power dispatching and control centers of all types and levels to realize smart grid operation control and optimized management.
The Elastic Dispatching and Control Support Platform is based on the advanced "Cloud-Native" design philosophy. It reconstructs traditional platform architecture using technologies such as containers, container orchestration, microservices, and service mesh to establish a data processing model and application support framework compatible with cloud computing. The platform breaks away from the centralized or grouped active/standby processing models of traditional monitoring software, implementing a cluster-based parallel processing model. This provides application systems with dynamic scalability for data acquisition, processing, and business services. Resource Layer: Provides the physical or virtual resources required for system operation, corresponding to conventional deployment and cloud computing deployment modes, respectively. In the cloud computing deployment mode, virtual resources are uniformly scheduled and managed through a cloud operating system.
The Real-time Power Balance and Optimized Dispatching Control System is a support system for real-time generation dispatching operations under electricity spot market conditions.

It features dispatch plan modification management and proactive power balance dispatching functions adapted to electricity spot market operations. Key functions include dispatch plan modification management, security checks for plan modifications, plan review, basic data management and monitoring, real-time power balance, unified grid-provincial peak shaving, and information aggregation and dissemination.
When the 110kV busbar of a 220kV plant or substation is de-energized, the smart restoration system uses real-time collected information to calculate a restoration path for the de-energized busbar. It fully considers factors such as main transformer current, 220kV busbar voltage, 110kV busbar voltage, station-level automatic transfer switches, line current margins, and data anomalies. The system generates a sequence of switch operations for open-loop or closed-loop control to quickly restore power to the busbar. If the restoration path indicates a current limit violation, it activates the interconnected overload shedding function, considering load priorities, load current magnitudes, and the amount of load that needs to be shed.
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.
