New Generation Power Grid Dispatching Technology

• A new generation of power grid dispatching technology support system construction plan is proposed in response to the "double carbon" strategy and the need to build a new power system.
• It focuses on constructing a new generation system for power system operation control, strengthening the platform and data foundation, and creating an open application ecosystem.
• The goal is to support regional power grid security, power supply, and clean energy consumption.
• The plan promotes transformation of dispatching from "equipment dispatching" to "power grid dispatching", from "fuzzy dispatching" to "transparent dispatching", and from "experience dispatching" to "intelligent dispatching".
• The aim is to aid the construction of a new type of power system regional power grid dispatching system.

Construction Principles

• The plan follows a scientific, systematic, and forward-looking approach.
• It is guided by the demands of new power system construction and power grid operation control.
• An approach of "inheritance + integration + innovation" is embraced.
• Mature technologies and construction results of the D5000 system are inherited
• Advanced ICT is combined, to integrate dispatching control domain technology innovation achievements and pilot experiences; to ensure the system is safe, coordinated, practical, open, and forward-looking

Overall Architecture

• The system architecture is divided into a platform layer, a data layer, and an application layer.
• The platform layer consists of operation control and dispatching cloud dual platforms.
• The data layer aggregates model data, real-time data from various business links, different time states, and various levels of dispatching.
• The application layer creates seven categories of business applications, forming four major functional centers: model management center, real-time monitoring center, analysis decision center, and intelligent application center.
• The regional new-generation system adopts a combination of on-site deployment and cloud deployment.
• The operation control platform and related applications are deployed on-site.
• The dispatching cloud platform and related applications are deployed on the cloud.
• Independently deployed human-machine cloud terminals can flexibly access the primary and backup systems, supporting the primary and backup dispatching business.

Security Protection

• The system follows the general policy of "safe zoning, dedicated network, horizontal isolation, and vertical authentication".
• Security protection is conducted from aspects such as structural security, entity security, application security, data security, security services, security monitoring, response and disposal, and security management.
• Security zones are rationally divided based on the characteristics of each business application, the importance of functional modules, and the functional differences of each node.
• The focus is on protecting the core businesses of the production control system.

Software Composition

• The software architecture is mainly divided into three parts: basic software, platform software, and application software.
• Basic software includes operating systems, relational databases, etc.
• Platform software includes operation control and dispatching cloud dual platforms, covering platform management, communication bus, model management, basic services, data services, human-computer interaction services, and other functional modules.
• Application software mainly includes real-time monitoring, automatic control, analysis and check, planning and forecasting, training simulation, dispatching management, big data, and artificial intelligence.

Hardware Composition

• Hardware architecture consists of servers, workstations, disk arrays, network security equipment, etc., deployed separately in the production control zone and management information zone.
• Redundant core switches are configured in the production control zone as the core aggregation nodes of the business processing network.
• The business aggregation switches are connected to the core switches through a network to realize the interconnection between various businesses in the production control zone.
• High-quality storage resources, application computing resources, and network security resources are provided for applications such as real-time monitoring, automatic control, analysis and check, and planning and forecasting.
• Hardware equipment in the management information zone achieves interconnection with the provincial dispatch through a comprehensive data network, providing hardware resource services for applications such as analysis and check, training simulation, and dispatching management.
• According to security protection requirements, network boundaries will be secured through vertical encryption devices and firewalls.
• Positive and negative isolation devices will be used between the production control zone and the management information zone for security isolation.
