Power grid side energy storage device

Abstract

According to the technical scheme, power grid side energy storage equipment is characterized by comprising a monitoring system, a monitoring center, an energy conversion system, a battery management system and energy storage medium equipment, wherein the monitoring system is used for acquiring voltage information and current information of a load input end and feeding the information back to the monitoring center; and the monitoring center judges the operation state of the load according to the voltage information and the current information of the load input end. In order to overcome the defects in the background technology, the invention provides power grid side energy storage equipment, and solves the problems of transformer area distribution and transformation overload, line overload and transformer substation transformer overload.

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...

Problems solved by technology

[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 level 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. performance and assessment indicators of power companies

The adoption of technical renovation, overhaul, and new construction often takes a long period of time and requires a large investment. For seasonal loads (migrant workers return to their hometowns to engage in agricultural production), the utilization rate of equipment is low, and the return on investment is extremely low.

Restricted by many factors such as project demolition compensation and cost increase, it is becoming more and more difficult to transform and increase the capacity of the power grid system

The traditional method of relocating and changing lines requires a large number of equipment such as changing lines, poles, and switches on poles to solve the overload problem of rural power grids. The construction scope is large and the cycle is long, so it is not economical to solve the overload of branch lines in the area.
