Energy storage power correction During peaking, ES will continuously absorb or release a large amount of electric energy. The impact of the ESED on the determination of ES capacity is more obvious. Based on this feature, we established the ES peaking power correction model with the objective of minimizing the ESED and OCGR.
Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.
The unique advantages of energy storage (ES) (e.g., power transfer characteristics, fast ramp-up capability, non-pollution, etc.) make it an effective means of handling system uncertainty and enhancing system regulation [, , ].
Due to the limitations of the maximum power of conventional units, the system needs a larger discharge power provided by ES to participate in peak shaving when the power of RE is small (e.g. Fig. 7 (Typical day 2 12:00 to 20:00 p.m.)).

As the core link in the energy storage industry chain, energy storage system integration (ESS) connects upstream equipment providers and downstream energy storage system owners, becoming a battleground for energy storage manufacturers.
Value chain depth and concentration of the battery industry vary by country (Exhibit 16). While China has many mature segments, cell suppliers are increasingly announcing capacity expansion in Europe, the United States, and other major markets, to be closer to car manufacturers.
Players in the battery value chain who want to localize the supply chain could mitigate these risks through vertical integration, localized upstream value chain, strategic partnerships, and stringent planning of manufacturing ramp-ups. The battery value chain is facing both significant opportunities and challenges due to its unprecedented growth.
In many respects, the current battery industry still acts as a linear value chain in which products are disposed of after use. Circularity, which focuses on reusing or recycling materials, or both, can reduce GHG intensity while creating additional economic value (Exhibit 14).
A resilient battery value chain is one that is regionalized and diversified. We envision that each region will cover over 90 percent of local cell demand, over 80 percent of local active material demand, and over 60 percent of refined materials demand.
