6 FAQs about [Ndrc grid-side energy storage]
What are NDRC & Nea's 'guiding opinions' on grid-side energy storage?
Regarding grid-side energy storage, in July 2021, NDRC and the National Energy Administration (NEA) issued the "Guiding Opinions on Accelerating the Development of New Energy Storage", wherein they advocated for the exploration of tariff mechanisms for grid-side independent energy storage capacity (NDRC and NEA, 2021).
What is a grid-side energy storage operator?
Regarding the operating model, the grid-side energy storage operator provides services to the grid, while the grid pays the energy storage plant operator for leasing the energy storage plant, which is the capacity tariff. The grid and energy storage operators often have conflicting interests as independent economic entities.
What is the capacity Tariff of grid-side energy storage?
Based on the capacity tariff calculation model of the Stackelberg game proposed in this paper, the capacity tariff of grid-side energy storage is 415.58 CNY/kW.
How does the grid-side energy storage choose to charge and discharge power?
Charge and discharge power and state of charge of the grid-side energy storage. According to Fig. 7, it can be seen that the grid-side energy storage chooses to charge at the time of low and flat electricity prices and discharge at the time of peak electricity prices.
Why do we need a grid-scale energy-storage system?
Under some conditions, excess renewable energy is produced and, without storage, is curtailed 2, 3; under others, demand is greater than generation from renewables. Grid-scale energy-storage (GSES) systems are therefore needed to store excess renewable energy to be released on demand, when power generation is insufficient 4.
Are battery energy-storage technologies necessary for grid-scale energy storage?
The rise in renewable energy utilization is increasing demand for battery energy-storage technologies (BESTs). BESTs based on lithium-ion batteries are being developed and deployed. However, this technology alone does not meet all the requirements for grid-scale energy storage.
