Problems solved by technology

Most of these studies lack the consideration of the characteristics of high communication delay, heterogeneous data and computing resources in the distributed computing environment in the wide area network environment, and have not established a decomposition that can uniformly handle the power flow balance and unbalanced power distribution of the entire network. Coordination calculation model, thus insufficient application ability in real power system

Embodiment Construction

[0076] The specific embodiments of the present invention will be described below in conjunction with the drawings:

[0077] Please refer to Figure 2, which is a schematic diagram of the basic process of distributed integrated power flow analysis;

[0078] It is an iterative algorithm with the help of Jaobian-free Newton GMRES(m), under the premise of preserving the independence of each dispatch center, only need to exchange boundary node status and regional power grid active loss information to complete the coordinated solution of the whole network power flow Methods. It can complete network-wide integrated power flow calculation that meets the following basic requirements:

[0079] a. All nodes in the entire network meet power balance;

[0080] b. The active power loss of the whole network is reasonably distributed among the regional power grids, that is, the active power loss of the whole network shared by each regional power grid according to a certain proportion;

[0081] c. I...

Abstract

The invention discloses a method of completing the distributed tide analysis by exchanging the border node state and the network damage information, which comprises: establishing a distributed tide analyzing system according to the actual scheduling management manner of the electric power system; based on the topology connection relations of the electric power system and the operation situations of the practical system, dividing the interconnected electric network by the dividing method with border area, and clarifying the counting objects and the data sources of the counting server and the coordinating counting server; a domain tide counting server and the superior coordinating counting server are initialized by counting data and parameters, while the coordinating counting server calls the domain tide counting server to together complete the network integrative tide decomposition coordinating solve; besides, the servers call the processes, the domain tide counting server feeds back the result to the coordinating counting server so as to make the coordinating counting server obtain the convergent network integrative tide result.

Description

Technical field [0001] The invention relates to a method for completing distributed power flow analysis, in particular to a method for completing distributed power flow analysis by exchanging boundary node status and network loss information, and belongs to the technical field of power system distributed simulation. Background technique [0002] With the continuous strengthening of power system interconnection, the composition of the power grid has become more complex, and the difficulty of operation has greatly increased. When a local failure occurs, if it is not handled properly, it will develop into a major accident that endangers the entire system. In order to improve the safety and stability of the interconnected power system, it is more and more necessary to perform an integrated simulation analysis of the entire power grid without simplification. [0003] my country's power grid is coordinated and managed by a multi-level dispatch center, and adopts a management system of ...
