What is the leasing model for energy storage projects?

Another such model is the leasing model for front-of-the-meter energy storage projects adopted by Hunan province in 2018, and the subsequent 2020 upgraded version of the leasing model which applied to energy storage paired with renewable generation and designed to split investment risks between each entity.

Which energy storage technologies have been made a breakthrough?

Breakthroughs have been made in a variety of energy storage technologies. Lithium-ion battery development trends continued toward greater capacities and longer lifespans. CATL developed new LiFePO batteries which offer ultra long life capabilities, while BYD launched "blade" batteries to further improve battery cell capacities.

What is the control system of the energy storage station?

The control system of the energy storage station adopts the IEC-61850 standard specification, achieving fast power control function through a unified hardware and software platform consisting of a coordinated control system and converter group. Primary frequency control and voltage control response speed is less than 30ms.

Why are energy storage technologies undergoing advancement?

Energy storage technologies are undergoing advancement due to significant investments in R&D and commercial applications. For example, work performed for Pacific Northwest National Laboratory provides cost and performance characteristics for several different battery energy storage (BES) technologies (Mongird et al. 2019).
