Transfer path selection method and system based on big data analysis

Abstract

The invention discloses a method for selecting a transfer route based on big data analysis, which sets a transfer route selection set S and the number of historical transfer routes, and establishes a power system total energy model; obtains a real-time transfer route selection set S 0 , to find the real-time total energy e of the power system 0 , to obtain the total energy of the simulated power system after the power transfer is implemented according to the transfer route; according to the solution result, all the transfer routes in the transfer route selection set are reordered; according to the information of the power flow section, the transfer route that satisfies the conditions is output; When there is a demand for power transfer, power transfer is performed according to the output transfer path. By setting the real-time transfer path selection method, big data analysis is performed on the selection of the transfer circuit, and an optimized transfer selection scheme is formed so that the power transfer can be carried out in a timely manner. At the same time, based on the total energy function, the adopted transfer path It can satisfy the system's demand for stability to the greatest extent.

Description

technical field [0001] The invention relates to a method for selecting a transfer route based on big data analysis, in particular to a method for selecting a transfer route based on big data analysis and a big data analysis system that can ensure the stability and safety of the system after the transfer route is implemented. Background technique [0002] The power output and load in the power system are in the process of real-time changes, and power lines and equipment usually fail due to the external environment, such as wind, rain, thunder, electricity, and their own life. Therefore, power transfer is a power It is a method commonly used in the system to re-guarantee the power supply when there is a power imbalance, so that the power can reach a balanced state again. [0003] However, the existing transfer methods only set the selected transfer mode after a fault occurs, which is an obstacle to the development of smart grids with stricter real-time requirements. During th...

[0003] However, the existing transfer methods only set the selected transfer mode after a fault occurs, which is an obstacle to the development of smart grids with stricter real-time requirements. During this period of time to choose the power transfer method, the power may impact all corners of the smart grid, which will bring disaster to various smart devices

Moreover, the conventional transfer method does not consider the change of the total amount of electric energy before and after the transfer. If the change is large, it will cause system oscillation and induce more serious secondary faults.
