6 FAQs about [Source-side energy storage and grid-side energy storage]
Why is energy storage important?
Energy storage is an important link for the grid to efficiently accept new energy, which can significantly improve the consumption of new energy electricity such as wind and photovoltaics by the power grid, ensuring the safe and reliable operation of the grid system, but energy storage is a high-cost resource.
What is the difference between power grid and energy storage?
The power grid side connects the source and load ends to play the role of power transmission and distribution; The energy storage side obtains benefits by providing services such as peak cutting and valley filling, frequency, and amplitude modulation, etc.
What is the energy storage system?
The energy storage system includes 1×5 MW×2 h LiB, 1×2 MW×2 h VRFB. And the wind power of 99 MW had been put into operation in August 2012. The system is connected with the 35 kV bus. Through intelligent control, the system stores and releases power according to the coordinating with wind power.
What are source grid load storage coordination measures?
Source grid load storage coordination measures. When energy storage is involved in market operation, it has certain time and space rules.
How will res' grid connection affect energy storage demand?
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 .
How does energy storage work?
In this case, the energy storage side connects the source and load ends, which needs to fully meet the demand for output storage on the power side and provide enough electricity to the load side, so a large enough energy storage capacity configuration is a must.
