Problems solved by technology

[0006] The traditional reactive power optimization method has strict data limitations, and it is difficult to fully utilize the advantages of big data. However, the application of big data technology in the field of distribution network is used for the global optimization of the power grid based on theoretical analysis based on data modeling, which breaks through the previous Random factor assumptions and simplifications

Embodiment Construction

[0044] The technical solution provided by the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] The DG output and load data in the reactive power optimization of distribution network have the characteristics of randomness and uncertainty. Different from the traditional single numerical representation method, big data tends to be described in the way of interval or probability density function. Provide more systematic and comprehensive data support. Distributed power generation and load forecasting in distribution network are special, and the statistical characteristics of the data are complex, so it is difficult to directly fit the probability density function. The invention aims to process the DG output and load data of the distribution network, convert them into a data format represented by a probability density function, and establish data support for reactive power optimization of the distribution network.

Description

technical field [0001] The invention relates to a data processing method in the field of distribution network, in particular to a data processing method for reactive power optimization of a distribution network. Background technique [0002] The distribution of reactive power flow in a power system not only directly affects the safety and stability of the power system, but is also closely related to economic benefits. Insufficient reactive power flow leads to system voltage reduction, and in severe cases, voltage collapse accidents are caused; while excessive reactive power flow leads to deterioration of system voltage quality, endangering the safety of the system and equipment, and too much reactive power reserve will waste unnecessary investment. Reasonable allocation of reactive power input and withdrawal can effectively reduce network loss, ensure voltage quality, prevent accidents, and prevent accidents from expanding, thereby improving the economy, safety and stability...
