Embodiment Construction

[0031] The present invention described in detail below realizes the construction of a prediction model for changes in the state of the distribution network, which aims to enable better regulation of the distribution network. More specifically, the method according to the present invention implements a learning method that aims to detect changes in the state of the distribution network so that it can be dynamically adjusted.

[0032] figure 1 The power distribution network 1 is shown. The distribution network 1 is connected to the power supply network 6 from its main node N via a transformer station 7 including a transformer 8 (for example, an MV / LV transformer).

[0033] At node N (or transformer station 7), a number of power distribution lines 3 feeds that supply current to a load 2 (the term "load" 2 is understood as a component that consumes power) can be counted. For example, the power distribution network 1 may be an LV network connected to an MV network (power supply network...

Abstract

A method for constructing a predictive model of a change of state of an electrical distribution network, the electrical distribution network including a node supplying power to loads connected by wayof a distribution line, the method including: a. a step of measuring the variation, during a first time period, of a physical quantity A at the main node, and of a physical quantity B at measuring points of the network; and b. a step of correlating the quantity A and the quantity B measured in step a., so that knowledge of the physical quantity A at the main node allows the value of the physical quantity B at the plurality of measuring points of the network to be predicted.

Description

Technical field [0001] The invention relates to a method for forming a prediction model of characteristic quantities of a distribution network. The invention also relates to the realization of a predictive model of characteristic quantities to ensure the stability of the distribution network, especially the low-voltage network. Background technique [0002] Generally, the low-voltage (LV) distribution network (low voltage means that the power supply voltage is less than 1000 volts) is provided at the main node. The low-voltage (LV) distribution network passes through the transformer station called MV / LV station, and passes through the main node. Voltage (MV) network (medium voltage refers to the power supply voltage higher than or equal to 1000 volts) connected. The LV network also includes multiple LV distribution lines that transmit current from the main node to users, such as household users connected to the LV network. [0003] The entire net is designed to assure consumers a...
