Abstract

The invention discloses a power grid model sharing method applicable to distributed computation of a power system. The method comprises: constructing a power grid physical model applicable to multi-stage scheduling integrated distributed computation; performing local and global verification on a distributed integrated power grid model sequentially; performing distributed storage and redundancy backup on the power grid model that passes the verification; enabling the power grid physical model that passes the verification; and integrating a large power grid distributed network topology analysis function and a distributed state estimation function to a model management center, and accessing to the power grid physical model and a computation model according to different demands of applications. According to the method, existing storage resources of distributed deployment of each scheduling center are fully used, and physical distributed storage and logic centralized management are performed on the power grid physical model and the computation model by using a distributed data deployment policy, so that the power grid model is constructed. Based on a distributed database technology and a distributed file system technology, full-network instant sharing of the power grid physical model and the computation model is implemented.

Description

technical field [0001] The invention relates to a maintenance sharing method, in particular to an instant sharing method of a power grid model suitable for online distributed computing of a power system. Background technique [0002] With the construction of my country's UHV interconnected large power grid and the access of large-scale distributed power sources, in order to support the power system dispatching business, it is objectively required that the power grid modeling range of the large power grid dispatching control system is larger and the accuracy is higher. The voltage level of the power grid has been developed up to 1000kV UHV power grid, and down to the fine modeling of distributed power grid access, and the scale of the power grid is rapidly expanding. In order to meet the needs of large-scale interconnected grid cross-regional, cross-voltage level cooperative computing and ultra-large-scale power grid computing, the new generation of smart grid dispatching con...
