A method for real-time maintenance of central model of power grid regulation model

Abstract

The invention discloses a model real-time maintaining method of a power grid regulation and control model center. The method includes the steps of classifying models on the levels of model objects andmodel object properties, establishing a model maintaining authority management method with a plant station as the granularity, completing the maintaining authority judgment through model service of the model center to realize distributed source end maintaining of the models within the jurisdiction range of the model center, establishing the consistency commit mechanism between the model center and an access subsystem, and coordinating the public model commit state between the model center and the access subsystem to realize the real-time maintaining of the models of the model center and the access subsystem. The distributed type source end maintaining requirements of the subsystem models are met, the maintaining complexity of the model center models is reduced, the updating timelines andexpandability of the model center models are improved, the strong consistency of power grid models of an all-stage access model center system is ensured, and bottom level model data support is provided for various subsequent online and offline applications at the model center.

Description

technical field [0001] The invention relates to a real-time maintenance method for a grid control model central model, belonging to the technical field of smart grids. Background technique [0002] With the deepening of the construction of the large-scale operation system of the State Grid, the current model assessment of various provinces, cities and sub-centers by the State Research Institute is becoming more and more stringent, and dispatching centers at all levels have carried out research work on related model management. Within the scope of the State Grid, dispatch centers at all levels have basically realized the sharing of public models through CIM / E-based model splicing technology. With the development of the smart grid model sharing technology, a new model sharing mode, the power grid model center mode, has emerged. The model center includes the model center system and the access subsystem (ie, the access grid dispatching control system). Compared with the traditi...

AI Technical Summary

Problems solved by technology

Compared with the traditional model sharing based on model splicing technology, this new model sharing method needs to meet the distributed source maintenance requirements of each access subsystem model, reduce the complexity of model-centric model maintenance, and improve the model-centric model. The timeliness and expansibility of the update require ensuring the strong consistency of the power grid models connected to the model center system at all levels, and there is no method that meets the above requirements at the same time
