Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0042] like figure 1 As shown, a site selection method for an energy storage system includes the following steps:

[0043] Step 1, according to the distribution network model, analyze the node voltage distribution before the energy storage system is connected to the distribution network, and obtain the voltage drop model between adjacent nodes;

[0044] Step 2, according to the voltage drop model between adjacent nodes, obtain the relationship model between the node voltage square item, the substation bus voltage square item and the node access load power;

[0045] Step 3. According to the relationship model between the node voltage square item, the substation bus voltage square item and the n...

Abstract

The invention discloses an energy storage system site selection method and system and a storage medium, node voltage square term sensitivity is adopted to replace traditional node voltage sensitivity, evaluation indexes are calculated through the node voltage square term sensitivity, energy storage system site selection is carried out, compared with a traditional method, the calculation complexity is greatly reduced, and the energy storage system site selection efficiency is improved. And the site selection efficiency is enhanced.

Description

technical field [0001] The invention relates to an energy storage system site selection method, system and storage medium, belonging to the field of energy storage system optimization control. Background technique [0002] With the rapid development of the economy, the power consumption of power users is increasing, and the requirements for voltage quality are getting higher and higher. On the one hand, during the peak period of power consumption by users, active power with high demand flows through the lines, resulting in large line losses, serious voltage drops, and low voltage problems; on the other hand, due to the construction level of the power distribution system The power transmission system is outdated, leading to more prominent voltage quality problems in the distribution network. At present, among the voltage quality problems, low voltage, voltage fluctuation and power supply voltage deviation are the most common. In response to such problems, traditional soluti...
