The technical scheme provided by the invention fully considers the factors of equipment commissioning, equipment decommissioning, equipment power-cut plan, call wire equivalence and the like, thereby ensuring the completeness and accuracy of the futuristic power grid model; and a topological logic relationship is used for carrying out equipment connection, thereby ensuring the rapidity for constructing the power grid model.

Description

technical field [0001] The invention relates to the technical field of electric power system dispatching planning, in particular to a method and device for constructing a model of a future power grid. Background technique [0002] At present, the day-ahead power generation planning method with safety-constrained dispatch as the core technology has been widely used in various power grids and provincial power dispatching control centers. With the advancement of the power market and bilateral transactions, the feasible space for power generation plans in power grids is getting tighter year by year. On the one hand, It is required to formulate mid- and long-term plans more reasonably on the basis of fully considering various practical constraints, so as to ensure that the power generation plan has better implementability, and create favorable conditions for realizing the annual pre-control target and meeting the needs of subsequent power grid operation; On the other hand, it is ...

AI Technical Summary

Problems solved by technology

Among the existing analysis methods, one is short-term simulation, which only considers the current power grid model and equipment maintenance plan, and does not consider new equipment; the other is long-term simulation, which only considers main network equipment, and performs maximum and minimum There is no time-based detailed model, which cannot meet the needs of future multi-time power grid mid- and long-term dispatching plans
