T/JES 007-2025 The technical requirements for the time-series production simulation technology of the new power system

Scope

Main technical content: The standard specifies the basic requirements for simulated input data of sequential production in the new power system. It is necessary to accurately collect and process data such as load, new energy output, grid topology, and unit operation characteristics. The data must have high collection accuracy and timeliness, and be subject to correction and standardized processing to ensure data consistency and accuracy. The standard also defines the basic form of simulated modeling of sequential production in the new power system, including an objective function aimed at minimizing generation costs, as well as system-level constraints covering power and energy balance, power flow, transmission, and reserve, and unit-level constraints such as unit output, ramp-up/down time, and start/stop time. According to specific needs, special constraints such as frequency safety can also be added. To accelerate the solution of sequential production simulation problems, techniques such as integer relaxation, linear relaxation, clustering, and decomposition can be used, or combined with artificial intelligence to optimize the solution process. In addition, tools such as GridView, GOPT, and PLEXOS can be used for simulation. The simulation results can be evaluated through indicators such as power and energy balance, line transmission power, carbon emissions, and fuel consumption to measure the economic, reliability, and environmental impact of the power system.
