Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] Such as figure 1 , the present invention provides a load optimization configuration method based on network operation efficiency, the method includes the following steps:

[0049] Step 1: Calculate the daily fitting load of sample users in the corresponding industry;

[0050] Step 2: Calculate the forecasted load of the stationed users;

[0051] Step 3: Select equipment for different combinations of stationed users, and calculate the wire load rate;

[0052] Step 4: Realize load optimal configuration by establishing load optimal configuration model.

[0053] In the step, the daily load of the sample users in the i-th type of industry is unitized with the maximum daily load of the user as the base value, and the value after the unitization is weighted average by the number of sample users selected in the i-th type of industry , to get the daily fitt...

Abstract

The invention provides a load optimal configuration method based on power grid operation efficiency. The load optimal configuration method comprises the following steps: calculating the daily fitting load of a corresponding industry sample user; calculating the prediction load of an entering user; carrying out equipment model selection to different entering user combinations, and calculating a conductor load rate; and realizing load optimal configuration by establishing a load optimal configuration model. The load carried by each distribution line in an industrial estate is optimized, so that network operation efficiency is improved, and a theoretical basis is laid for the planning of a power distribution network.

Description

technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof, and in particular relates to a load optimization configuration method based on power grid operation efficiency. Background technique [0002] The distribution network is the part closest to the user in the power network. Scientific optimization planning for it can ensure the rationality of power grid construction and transformation, the safety and economy of power grid operation, and improve the power supply quality of the distribution network. At present, there are many studies on urban medium and low-voltage distribution networks in the academic circles, focusing on discussing how to optimize the construction site and capacity of new substations and feeders to obtain a distribution network construction plan with low operating investment and high reliability. Among them, load forecasting is aimed at the expansion of aggregated load points. However, there ar...
