Abstract

The invention discloses a multi-transmission-section cooperative control assistant decision early warning control method and system, and the method comprises the steps: obtaining a preset parameter, and determining a power transmission section set needing to be controlled and a control target of each power transmission section according to the preset parameter; according to the preset parameters,determining the range of adjusting equipment and the priority of the adjusting equipment; according to the preset parameters, the range of the adjusting equipment, the priority of the adjusting equipment and a cooperative control model, determining a multi-transmission-section cooperative control auxiliary decision scheme; according to the multi-transmission-section cooperative control auxiliary decision scheme and a preset threshold value, early warning control is carried out on a power grid; by calculating the control performance index and comprehensively considering the effectiveness and the adjustment priority of the adjustment measures, the cooperative control auxiliary decision scheme is generated for the multiple power transmission sections in the large power grid, the problem of cooperative control of the multiple power transmission sections is solved, control decision suggestions are provided for dispatchers, and safety early warning control of the large power grid is achieved.

Description

technical field [0001] The invention relates to the field of online security and stability calculation and analysis of electric power systems, and more specifically, relates to a multi-transmission section cooperative 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 the large power grid is an important guarantee for the safe and stable operation of the power grid. With the rapid development of my country's regional power grid interconnection and the steady advancement 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 large power grid, develop advanced safety and stability control technology for l...
