AI Technical Summary

Technical Problem

Traditional single-stage planning methods cannot meet the load requirements of regional integrated energy systems under future extreme climate conditions, resulting in equipment capacity redundancy, affecting the system's economy and security, and ignoring changes in demand and energy prices.

Method used

A multi-stage planning approach is adopted, combining future extreme weather forecast data and building load calculations, taking into account carbon capture equipment and power-to-gas conversion equipment, to establish objective functions and constraints, optimize equipment capacity and operating strategies, and improve system flexibility and economy.

Benefits of technology

Through multi-stage planning, we can optimize equipment configuration and operation, reduce carbon emissions, improve the economy and safety of the system, meet load demands, and enhance the system's flexibility and adaptability.
