        "summary": "Huawei has unveiled its LUTERRA Smart String Grid-Forming ESS Platform, integrating breakthroughs in electrochemistry and power electronics to achieve industry-leading efficiency. The platform features a patented Through-Busbar architecture for simplified installation and reduced costs, alongside proven grid-forming technology that provides inertia and stability for renewable-heavy grids. This solution aims to enhance energy throughput and optimise integration with solar plants, building on Huawei's experience with the world's largest 100% renewable microgrid in Saudi Arabia.",
        "content": "<p>Huawei launched LUTERRA at the Intersolar Europe event in Germany\nlast month. According to Steve Zheng, President of Smart ESS Business at\nHuawei Digital Power, the company has delivered a battery energy storage\nsolution that is easy to install, boasts industry-leading efficiency,\nand supports grid-forming (GFM) applications at the power plant level.\nHuawei\u2019s grid-forming technology has been proven through various field\nimplementations, including the world\u2019s largest 100% renewable energy\nmicrogrid located in The Red Sea tourist area in Saudi Arabia. Having\noperated stably for more than two years, this project demonstrates that\nthe coordination of grid-forming energy resources across multiple sites\ncan be applied at the gigawatt-hour scale. Although few projects match\nthe scale of The Red Sea facility\u2014which features a 400 MW solar power\nplant and a 1.3 GWh Battery Energy Storage System (BESS)\u2014Huawei\u2019s\ntechnology still helps customers increase revenue, throughput, and\nachieve more optimal integration with solar plants. According to Zheng,\nadvantages such as industry-leading round-trip efficiency (RTE),\nhigh-precision state of charge (SOC) control, and cell-to-pack\noptimisation are achieved through a combination of disciplines, ranging\nfrom electrochemistry, electrical engineering, and electronics to\nthermodynamics, control technology, and predictive technology. \u201cHuawei\ncontrols all aspects of the solution comprehensively, enabling it to\nachieve 91.3% efficiency on the low-voltage side of the PCS at an\nambient temperature of 25\u00b0C. Furthermore, SOC accuracy reaches 2.5% at\nboth ends of the operational range and 3% in the plateau area,\u201d Zheng\nstated. The integrated design encompasses comprehensive thermal\nmanagement from the cell level to the battery pack, a liquid cooling\nsystem, and a high-voltage silicon carbide (SiC) switching architecture.\nThis combination provides a distinct advantage for Long-Duration Energy\nStorage (LDES) applications compared to other products available on the\nmarket. \u201cWe maintain the string architecture and apply an optimizer to\neach battery pack and a controller to each rack. This detailed and\neffective approach can overcome electrochemical inconsistencies,\nincluding characteristic differences that emerge throughout the battery\nlife cycle,\u201d Zheng explained. He added, \u201cHuawei\u2019s latest generation\nsolution increases the AC voltage to 1000V AC for the first time by\nutilising SiC components. This step also reduces energy loss and\nimproves system efficiency. The intelligent distributed cooling\ntechnology increases the heat dissipation area. On the other hand, the\ncombination of RTE, consistency, SOC level, and high system availability\ncan improve throughput by more than 10% compared to conventional\nsolutions.\u201d Despite incorporating complex technology, Huawei designed\nthe installation and logistics process to remain simple. In a 1 GWh BESS\nproject example, the LUTERRA Smart String Grid-Forming ESS Platform can\ncut delivery time by at least 30%, lower balance of plant (BOP) costs by\na minimum of 20%, and reduce land requirements by one square metre for\neach megawatt-hour of installed capacity compared to conventional\nsolutions. According to Zheng, this achievement is supported by Huawei\u2019s\npatented Through-Busbar architecture. This technology supports a more\nflexible installation process, easier capacity expansion, and C-rate\nadjustments for the charging and discharging process throughout the\nproject\u2019s life cycle. Grid-forming technology is playing an increasingly\nimportant role in maintaining power system stability in various\ncountries, especially with the growing utilisation of renewable energy.\nHistorically, the frequency and voltage of the power system were largely\nformed by the rotation of thermal power plant turbines. However, as\nfossil fuel-based generation begins to be replaced or becomes less\ndominant compared to Variable Renewable Energy (VRE) sources, new\nchallenges arise in maintaining system stability. Inverters with\ngrid-forming capabilities can provide similar functions, including\ninertia, short-circuit ratio (SCR), and black start features. Therefore,\nGFM technology is considered highly suitable for application in BESS.\nCountries such as the United Kingdom, Australia, and China are also\nbeginning to develop grid-forming-based resources. In Europe, four\nGerman transmission system operators (TSOs) launched a long-term inertia\nservices market earlier this year that can be participated in by\nGFM-based BESS assets. Meanwhile, ENTSO-E, representing transmission\nsystem operators from 36 European countries, has drafted technical\nguidelines on grid-forming standards. \u201cGrid-forming technology is key to\nmaintaining the stability of power grids integrating a large share of\nrenewable energy. This technology has evolved from the individual\nequipment level to array systems and up to power plants,\u201d said Zheng.\nHuawei defines six main features of grid-forming: inertia, short-circuit\nlevel, primary frequency regulation, power oscillation damping, black\nstart, and on\/off-grid switching in virtual synchronous generator (VSG)\nmode. \u201cWe believe that the technological breakthrough of grid-forming at\nthe power plant level is a very important factor,\u201d he continued. In a\n100 MW BESS installation, for instance, thousands of power electronic\ndevices must operate in GFM mode simultaneously, ensuring all these\ndevices can work in harmony.<\/p>",
