fast technology reported on september 9th,according to media reports, the 2024 international digital energy exhibition was officially held, and yang yougui, senior vice president of huawei and president of huawei digital energy global marketing service system, was invited to attend the exhibition.he also delivered a keynote speech at the opening ceremony and main forum titled "grid forming: building the world's largest microgrid - red sea, lighting up every 'electricity island' in the world".

yang yougui said that the middle east is currently actively seeking energy transformation."red sea new city" is the world's first green city that relies entirely on 100% photovoltaic and energy storage for power supply. it covers nearly 28,000 square kilometers and is expected to receive one million tourists each year.

the project not only has an international airport, 50 hotels and more than 8,000 luxury rooms, but also includes urban infrastructure such as desalination, sewage treatment and refrigeration. this project is a key part of saudi arabia's "vision 2030" plan.

looking back over the past three years, huawei has worked with industry partners to build the world's largest photovoltaic and energy storage microgrid power station. with a powerful combination of 400mw photovoltaic installed capacity and 1.3gwh energy storage capacity, it spans a grid layout of hundreds of kilometers and continuously supplies green electricity to the "red sea new city", demonstrating huawei's deep strength and outstanding contributions in the field of energy transformation.

as early as ten years ago, huawei's digital energy business proactively laid out the research and development of "grid-forming" technology, bringing together more than 30 top scientists and doctors, deeply integrating digital technology, power electronics technology and innovative grid forming technology, and successfully creating a world-leading grid-forming technology system, laying a solid foundation for the intelligent transformation of the energy industry.

since september 2023, the red sea 100% new energy microgrid system has been operating stably for a full year, contributing more than 1 billion kwh of green electricity, which has not only significantly reduced energy costs, but also achieved an excellent result of less than 10 cents per kwh.it is only about one-third of the cost of traditional diesel power generation, providing saudi customers with a highly competitive lcoe (levelized cost of electricity) solution.

it is particularly worth mentioning that as the world's first gw-level demonstration project using grid-connected energy storage technology, this project marks that smart string-type grid-connected energy storage technology has officially entered a new stage of large-scale commercial application, setting a new benchmark for the green transformation of the global energy structure.
