Embodiment Construction

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

[0048] Such as figure 1 , The present invention provides a load optimization configuration method based on network operation efficiency, and 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 predicted load of stationed users;

[0051] Step 3: Equipment selection for different combinations of stationed users, and calculation of wire load rate;

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

[0053] In the said step, the daily load of the sample users in the i-th type of industry is standardized with the maximum daily load of the user as the base value, and the standardized value is weighted average by the number of sample users selected in the i-th type of industry , Get the daily fitting load of the ...

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 power systems and their automation, and specifically relates to a load optimization configuration method based on the operation efficiency of the power grid. Background technique [0002] The distribution network is the part of the power network that is closest to the user. Scientific optimization planning for it can ensure the rationality of grid construction and transformation, the safety and economy of grid operation, and improve the quality of power supply of the distribution network. At present, academia has conducted a lot of research on urban medium and low voltage distribution networks, focusing on how to optimize the construction location and capacity of new substations and feeders to obtain a distribution network construction plan with low operating investment costs and high reliability. Among them, load forecasting is aimed at the deployment of aggregated load points. However, there is little resea...
