A multi-transmission section collaborative control auxiliary decision-making early warning control method and system

Abstract

The invention discloses a multi-transmission section collaborative control auxiliary decision-making early warning control method and system. The method includes acquiring preset parameters, and determining a set of transmission sections to be controlled and a control target of each transmission section according to the preset parameters; The preset parameters determine the scope of the adjustment equipment and the priority of the adjustment equipment; according to the preset parameters, the scope of the adjustment equipment, the priority of the adjustment equipment and the cooperative control model, determine the multi-transmission section The cooperative control auxiliary decision-making scheme; according to the multi-transmission section cooperative control auxiliary decision-making scheme and the preset threshold, early warning control is performed on the power grid; the present invention comprehensively considers the effectiveness of the adjustment measures and the adjustment priority by calculating the control performance index, and aims at large The multi-transmission section in the power grid generates a collaborative control auxiliary decision-making scheme, which solves the problem of collaborative control of multiple transmission sections, provides control decision-making suggestions for dispatchers, and realizes large-scale power grid security early warning control.

Description

technical field [0001] The invention relates to the field of on-line security and stability calculation and analysis of power systems, and more particularly, to a multi-transmission section collaborative control auxiliary decision-making early-warning control method and system. Background technique [0002] Power grid security is related to national security, and the security and stability control of large power grids is an important guarantee for the safe and stable operation of power grids. With the rapid development of power grid interconnection in my country and the steady progress of UHV power grid construction, the technical level and complexity of power grid operation are getting higher and higher, and the difficulty of power grid operation control is becoming more and more difficult. In this context, it is urgent to fully grasp the operation rules of such a super-large power grid, develop advanced large-scale power grid security and stability control technology, and ...
