Abstract

The invention discloses an interconnected electric network distributed current calculating method which is based on alternation and iteration of current module. The method comprises that initiation is carried out to current calculating module data of an inner net and an outer net firstly; alternation and iteration of the inner net current calculating module and the outer net current calculating module are carried out in a current calculating task computer of the inner net dispatching and controlling centre so as to present linkage of electric relationships of the inner and outer nets, therebyconverging two independent currents into a uniform target current solution. The method employs an integrated calculating mode, so as to avoid complex work of prototype model splicing and computation module splicing; the method has precise calculation result and strong integrity and is free of special requirements to current calculating module and algorithm. Therefore, the method can be widely applicable to various application areas of power network analysis, such as EMS, DTS, offline power network operation analysis and calculation and so on. Therefore, the method has relatively strong popularization and application value.

Description

technical field

[0001] The present invention relates to a distributed power flow calculation method for interconnected power grids, in particular to a power flow calculation problem for multiple dispatching control centers with electrical connections in the power grids under their jurisdiction, and a distributed power flow calculation for interconnected power grids based on alternating iterations of power flow modules The method belongs to the technical field of power grid dispatching automation. Background technique

[0002] The power system is a complex large system composed of power plants, substations, transmission and distribution networks and users, which are dispatched and operated in a unified manner. In the power system, since most of the power points and load centers are located in different regions, and the electric energy cannot be stored in large quantities, the balance between electric energy production and consumption must be maintained at all times. The powe...
