Although once considered the missing link for high levels of grid-tied renewable electricity, stationary energy storage is no longer seen as a barrier, but rather a real opportunity to identify the most cost-effective technologies for increasing grid reliability, resilience, and demand management.
And the pressure of RES' grid connection will also force the acceleration of wind-solar energy storage. It is predicted that with the continuous development of smart grid and RES' grid connection, energy storage demand during the "13th Five-Year" will further arise and reach to 50 billion yuan in year 2020 .
At present, China's power grid peak-shaving mainly depends on PSS . But PSS is subject to geographical conditions. Small peak-shaving system, like high-capacity energy storage battery, can realize multiple-point peak load regulation on the micro level and is unconstrained by geographical condition.
So to speak, energy storage is the precondition of large-scale integration and consumption of RES. However, China's energy storage industry is at the exploration stage and far from commercialization. This restricts the development of RES to certain extent. For this reason, this paper will concentrate on China's energy storage industry.
Judging from the present condition, cost problem is the main barrier. And the high performance and high security of the relative technology still need to be improved. Until 2020, energy storage industry in China may not be spread massively and the key point during this period is the technology research .
Grid-scale storage refers to technologies connected to the power grid that can store energy and then supply it back to the grid at a more advantageous time – for example, at night, when no solar power is available, or during a weather event that disrupts electricity generation. but they play a comparatively small role in current power
