shenzhen news network, september 9, 2024 (shenzhen special zone daily reporter zou yuan) the "big watt" electric humanoid robot can chat and generate inspection reports; the industry's first liquid-cooled 10-meter-class mobile energy storage vehicle with the world's largest capacity is not only safe and reliable but can also be "stored" at any time... at the 2024 international digital energy exhibition which opened on september 8, global leaders in the field of energy and digital technology brought the latest green grid and digital grid technologies, intelligent power distribution and utilization terminal equipment, and energy storage products, fully demonstrating that the energy industry is moving towards a greener, more efficient, and smarter direction.

smarter electricity services move towards large models

at the opening ceremony of the exhibition, an electric robot that deeply integrated large-scale model technology attracted attention. this deeply integrated product launched by china southern power grid company using large-scale model and humanoid robot technology, through the innovative "self-developed brain model + customized embodiment" design, realizes smooth voice dialogue, free body interaction, flexible movement and walking, precise power operation and other functions, accurately adapting to the diversified needs of the power industry.

"a machine truly becomes productive when it can proactively identify and complete tasks as a whole, just like humans," said liang shouyu, senior strategic technical expert at china southern power grid. "big watt" is a series that uses a vast amount of world knowledge for training as well as a large amount of power industry knowledge, and possesses the capabilities and attributes of the power industry.

this robot has demonstrated new capabilities in key scenarios such as power marketing services, facility and equipment inspections, switching operations, and live operations, significantly reducing operation and maintenance costs and operational risks, and injecting new impetus into the intelligent transformation and efficient operation of the power industry.

more precise low-carbon regulation improves energy efficiency

at the exhibition, shenzhen virtual power plant was upgraded again, releasing the control and management cloud platform 3.0, and launching new low-carbon scheduling technologies, allowing electricity to follow "green" movement with one click.

cheng renli, general manager of shenzhen virtual power plant management center, said that through "electricity + computing power" means such as green electricity tracking technology and remote signaling technology, the 3.0 platform starts from the local power generation source and calculates and monitors the "carbon trajectory" of the power transmission process throughout the entire process. it also integrates the carbon emissions of the power system and the power supply and demand situation, and scientifically implements peak shaving and valley filling to maximize the reduction of carbon emissions.

the 3.0 platform has connected to 55,000 adjustable load resources in nine categories, including charging piles, building air conditioners, photovoltaics, etc., with a total capacity of more than 3.1 million kilowatts, which is 60 times larger than when the platform was launched in 2021. li jiangnan, manager of the shenzhen virtual power plant management center, said that with advanced communication collection technology, the platform's data processing capacity has jumped from 100,000 to 1 million at the beginning of its launch, and the overall perception timeliness has entered the millisecond level.

as of august this year, the shenzhen virtual power plant control and management cloud platform has carried out 71 load adjustments, reducing carbon dioxide emissions by 2,273 tons. the launch of the low-carbon dispatch function will achieve greater energy conservation and emission reduction. the platform is expected to reduce carbon dioxide emissions by 3,000 tons by the end of this year.

more convenient mobile energy storage vehicles to ensure power supply

a small truck with a body length of about 10 meters has a capacity of up to 2mwh. sunwoda has brought the industry's first liquid-cooled, 10-meter-class mobile energy storage vehicle with the world's largest capacity, equipped with a self-developed and self-produced 314ah battery cell with 12,000 cycles for energy storage, as well as an ultra-high-power 800kw energy storage inverter and two 120kw fast charging guns, with a maximum output of 240kw fast charging power.

the person in charge of the xinwangda booth told reporters that unlike the common separation of car and battery, this mobile energy storage vehicle adopts an integrated structure. while ensuring the high energy of 2mwh, the body of the vehicle is more than 3.4 meters shorter than the common mobile energy storage vehicle. the vehicle's driving flexibility is greatly improved, and it can adapt to communities, small roads, mountains and other places with smaller turning sizes, reducing the difficulty of driving operations and adapting to more application scenarios.

the person in charge said that mobile energy storage vehicles can provide integrated charging and storage solutions in five major sub-sectors, including power grid inspection and operation and maintenance, disaster relief, medical treatment, field exploration operations or oil and gas extraction construction, and power supply for large-scale events.
