Power distribution network operation efficiency evaluation method and system based on big data mining

Abstract

The invention discloses a power distribution network operation efficiency evaluation method and system based on big data mining, and relates to the field of the power distribution network monitoring and control. The method comprises the following steps: collecting a power distribution network operation efficiency evaluation parameter, and establishing a power distribution network operation efficiency evaluation parameter database; constructing at least a multiple linear regression model, an exponential smoothing model, a first-order/second-order self-adaptive combination model and a neural network parameter optimization model; and evaluating and/or predicting the power distribution network operation efficiency by using the multiple linear regression model, the exponential smoothing model,the first-order/second-order self-adaptive combination model and the neural network parameter optimization model. By mining the relativity big data of the power distribution network, the distributionnetwork equipment and system operation efficiency, the coordination and the equipment equilibrium degree, the public power grid capital, and the user dedicated capital efficiency are analyzed according to different power supply regions and function zone types, and the influence factors with low efficiency are mined, thereby forming an efficient tool for distribution network efficiency monitoring,and a certain tendency pre-judgment and estimation function is provided.

Description

technical field [0001] The invention relates to the field of distribution network monitoring and control, in particular to a method and system for evaluating the operating efficiency of a distribution network based on big data mining. Background technique [0002] As one of the six major links of the power grid, the distribution network directly facing users is the key link to ensure the quality of power supply, improve the efficiency of power grid operation, and innovate user services. Therefore, the construction of the distribution network is related to the stability of the entire power grid and the power quality of users. Especially after the country vigorously develops the smart grid, the construction of the distribution network is particularly important. How to ensure that the distribution network provides high-quality power supply for the regional economic and social development and the improvement of people's living standards is the main problem faced by the distribut...

AI Technical Summary

Problems solved by technology

However, due to the limitations of historical conditions, my country's power grid has not been planned uniformly, and the economic benefits of power grid operation are low, especially in the economic operation of the distribution network, and there are many deficiencies in line loss calculation and analysis.

Although the economic efficiency of distribution network operation has been greatly improved after the construction and transformation of the power grid, there are still problems such as large power loss, low voltage, unreasonable layout of substations, and too long power supply radius.

In addition, with the change of electricity load, the originally planned power grid may not necessarily adapt to the current load development
