Description

technical field

[0001] The invention belongs to the technical field of electric power systems, and in particular relates to an energy storage device on the grid side. Background technique

[0002] Due to factors such as load growth, old equipment, and seasonal load changes, problems such as peak loads, transformers, and line equipment overloads have become increasingly prominent, seriously affecting the reliability, quality, and customer service of local power supply. With the development of electrification, especially during summer, winter, and holidays, line overload leads to switch tripping, low voltage in the station area, and three-phase load unbalance. and the assessment indicators of power companies. The adoption of technical overhaul and new construction measures often have a long cycle and large investment. For seasonal (migrant workers returning to their hometowns to engage in agricultural production) loads, the utilization rate of equipment is low, and the return...
