Banji Energy Storage Valley Project Planning Scheme

Which provinces have the largest energy storage capacity in 2035?

A multi-objective model for optimizing energy storage capacity and technology selection. Six energy storage technologies are considered for China's 31 provinces in seven scenarios. Accumulated energy storage capacity will reach 271.1 GW-409.7 GW in 2035. Inner Mongolia, Qinghai, and Xinjiang are the provinces with the largest capacity in 2035.

Can a non-linear multi-objective planning model support long-term energy storage capacity planning?

To support long-term energy storage capacity planning, this study proposes a non-linear multi-objective planning model for provincial energy storage capacity (ESC) and technology selection in China. The model aims to minimize the load peak-to-valley difference after peak-shaving and valley-filling.

Is pumped storage a viable energy storage technology?

However, pumped storage, an energy storage technology with water as the medium, is limited by water resources and mature technology; thus, it has limited cost reduction space and a relatively slow cumulative power capacity growth rate. By 2035, the cumulative power capacity will account for only 8.9% (pre-Ef) to 27.8% (pre-Co).

What is the energy storage technology selection and capacity allocation model?

The proposed model provides quantitative decision-making guidance for formulating a country's energy storage technology selection and capacity allocation schemes.

Which energy storage technologies reduce peak-to-Valley difference after peak-shaving and valley-filling?

The model aims to minimize the load peak-to-valley difference after peak-shaving and valley-filling. We consider six existing mainstream energy storage technologies: pumped hydro storage (PHS), compressed air energy storage (CAES), super-capacitors (SC), lithium-ion batteries, lead-acid batteries, and vanadium redox flow batteries (VRB).

What is the new energy storage capacity in 2035?

Under the BAU, H-B-Ma, H-S-Ma, L-S-Ma, and L-S-Mi scenarios, the new power capacity in 2035 will be the largest, ranging from 47.2 GW to 73.6 GW. Under the L-B-Mi and H-B-Mi scenarios, the maximum new energy storage power capacity obtained in 2034 was 33.9 GW and 55.1 GW, respectively.
