Technical Requirements for Power Flow Coordination Control of AC/DC Hybrid Systems - T/JES 003-2025

Scope

Main technical content: This standard specifies the basic technical requirements for intelligent coordinated control of power flow in AC-DC hybrid systems. Based on the multi-level architecture and operational characteristics of AC-DC hybrid systems, this standard formulates power flow coordinated control models and strategies suitable for different operational scenarios, covering all aspects of steady-state power flow distribution optimization, dynamic power flow adjustment, and global optimization control. The control models of AC-DC hybrid systems should comprehensively reflect the topological structure, electrical characteristics, and dynamic response capabilities of both the AC and DC sides, covering converter control models, grid load models, and new energy access characteristics. Optimized control should be based on multi-objective strategies, combined with wide-area coordinated algorithms and data-driven methods, to meet the operational needs of the system in both steady-state and dynamic conditions. Voltage and power control on both the AC and DC sides should take voltage stability, power balance, and network loss optimization as the core objectives, and control strategies should be formulated based on key parameters. Real-time data collection and processing provide decision support through intelligent sensors and big data analysis technologies, ensuring comprehensive perception and precise control of the system's operating status. The evaluation of power flow control effects should comprehensively consider network loss optimization, voltage stability, system response capability, and operational reliability. By setting key indicators such as network loss rate, voltage deviation, and control response time, the economic and practicality of the control strategy can be fully measured.
