Battery energy storage technology will ensure the stability of renewable energy generation

In recent years, the share of renewable energy generation has gradually increased, and renewable energy is not only regarded as solving environmental problems, but may be one of
the most important solutions to human energy needs in the long term.
China is facing severe environmental pressures and is therefore placing greater emphasis on the development of
renewable energy generation.
China has the world's largest demand for electricity and the largest renewable energy generator, so China is important
to the global development of renewable energy.

It is understood that the biggest problem in the development of renewable energy power generation is the intermittency and unpredictability of renewable energy power generation
.
On the one hand, there is an inconsistency between the concentrated time period of renewable energy generation and the time period of electricity consumption, on the other hand, with the change of seasons and weather, the curve of renewable energy generation and electricity consumption will change
accordingly.
In the longer term, battery storage may be the most effective economic solution
for the instability of renewable energy generation.

The advantages of battery energy storage are that it can be large or small, easy to combine with renewable energy power generation of various scales, fast charging and discharging, direct electricity and electricity conversion, and high
conversion efficiency.
The biggest limiting factor is economy, as well as the cost-related charge and discharge efficiency, safety, and life
.
Conventional wisdom holds that battery energy storage is expensive and difficult to operate
commercially.
