The invention relates to the technical field of power distribution, in particular to an active power distribution network power quality evaluation method and device, a terminal and a storage medium, and the method comprises the steps: obtaining a node index, finding a sample index through the index, associating the sample index with an active power distribution network node, transmitting the sample index to a trained evaluation model, and outputting a score. Through the mode of obtaining the index, the transmission amount of the data can be reduced, and through the mode of the comparison table, the calculation amount of the data can be reduced. The sample index obtained by indexing is obtained according to the class center, and the class center is approximate to the sampling data, so that more data details are reserved, and the problem of loss of details during data processing is reduced.
Description
technical field [0001] The invention relates to the field of power distribution technology, in particular to a method, device, terminal and storage medium for evaluating the power quality of an active distribution network. Background technique [0002] Electric energy is an indispensable and important energy in human society, and power quality is one of the three major goals of power grid operation, but there is no relatively perfect method to quantitatively and qualitatively evaluate the power quality. As a commodity, electric energy has strict requirements on quality. [0003] With the rapid development of new energy power generation technologies such as solar energy, wind energy, and biomass energy in recent years, the stability of the main power grid will be affected to a certain extent after being connected to the grid due to its characteristics of volatility, randomness, intermittency, and unschedulability. At the same time, with the development of microelectronics te...
