Technical Field

Background

With the global energy supply shortage, global climate change and environmental pollution in recent years, more and more countries recognize the importance of new energy, and are in vigorous development of new energy power generation, especially wind power generation, photovoltaic power generation and the like. The solar power generation and the wind power generation have received great attention due to the advantages of little environmental pollution and inexhaustibility in development and utilization of clean energy power generation such as solar power generation and wind power generation. However, wind energy and solar energy are greatly influenced by weather conditions and geographical environments, so that a lot of defects are brought when the grid is connected on a large scale. The power output of renewable energy power generation has the characteristics of fluctuation and randomness, and serious threats are brought to the stability and the safety of a power system. Along with the large-scale power generation grid connection of solar energy and wind energy, the pressure of frequency modulation and peak shaving is increased for the power dispatching department, and meanwhile, the power quality of a power grid is reduced due to the fluctuation of power and frequency. In addition, the renewable energy sources such as wind energy, solar energy and the like are unevenly distributed, and most of the renewable energy sources are in remote western regions and coastal areas, so that the running cost of long-distance power transmission is increased.

With the continuous development of distributed power generation technology and the increase of the power generation scale of new energy, in order to improve the output characteristic of an electric field, power enterprises often configure an energy storage system in a power distribution network for improving the grid-connected capacity of the new energy such as wind power and photovoltaic power generation. The energy storage system can play a role in peak clipping and valley filling, namely the energy storage system absorbs redundant electric energy in the system for storage when the load is low in the valley, and releases the stored electric energy to supply to the system load when the load is high in the valley, so that the peak-valley difference value at night in the day is eliminated, the reliability of power supply and the stability of operation are ensured, and good voltage quality is ensured.

The energy storage mode can be divided into mechanical energy storage, electromagnetic energy storage and chemical energy storage according to the difference of working principles. The chemical energy storage mainly refers to storage battery energy storage, and a storage battery energy storage system is the most widely applied energy storage system at present. The energy storage converter is used as key control equipment in the storage battery energy storage system, so that the charging and discharging control problem can be better solved, the control precision of the system is improved, and the service life of the system is prolonged. However, most energy storage converters in the prior art have poor heat dissipation conditions, so that the problems of low integration level of all parts, large equipment size, troublesome installation, high failure rate and the like are caused.
