Problems solved by technology

[0005] Because the traditional provincial dispatching system does not have a detailed load-pull model, in real-time control, when an emergency occurs in the system and the emergency recovery cannot be completed simply by adjusting the output of the generator, it cannot give accurate and reasonable load shedding measures. At the same time, there is also a lack of comprehensive and accurate analysis and calculation of active power adjustment strategies under anticipated faults

Embodiment Construction

[0061] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0062] The present invention is applied to the active power adjustment strategy analysis module of the provincial power grid dispatching automation. By adopting the active power adjustment strategy analysis method based on the load pull model, the function of accurately calculating the number of loads to be removed in the active power adjustment and predicting the risk of failure accidents is realized.

[0063] The working process of the provincial-level dispatching active power adjustment method considering the load-pull model provided by the present invention is as follows: figure 1 As shown, the method includes the following steps:

[0064] (1) Submit the route model information of the local survey to the provincial survey;

[0065] Use the transmission specification of the pull-road model between provincial and loca...

Abstract

The invention relates to a provincial dispatch active regulation method for a considering load switch-off model. The method comprises the steps as follows: (1) regional dispatch uploads regional dispatch switch-off model information to provincial dispatch; (2) a provincial dispatch switch-off model is constructed; (3) a provincial dispatch real-time active regulation policy is analyzed; and (4) a provincial expected failure active regulation policy is analyzed. The method provided by the invention improves accuracy and practicability of provincial dispatch real-time active control and the expected failure active regulation policy via acquiring load switch-off model information from a regional dispatch system in an online manner and combining an active optimization analysis technology.

Description

technical field [0001] The invention relates to the field of electric power system calculation, in particular to a method for adjusting active power in provincial dispatching taking into account a load-pull model. Background technique [0002] In recent years, with the continuous development of my country's electric power construction, the degree of interconnection of power grids has become increasingly close, and the structure has become increasingly complex. While improving cross-network transmission capacity and optimizing resource allocation, the potential threat of cascading failures in the power system and causing large-scale power outages in the power grid has also greatly increased. Especially in recent years, the load in some areas has increased rapidly, and it is easy to cause some equipment to be overloaded or exceed the limit, which makes the safe operation of the system face greater risks. [0003] Under the current operation mode of pulling and limiting electr...
