SNEC 2021: Huawei Digital Power Pushes for Carbon Neutrality through Convergence of Energy and Information Flow

By Huawei

With the theme of “Leading power digitalization for a zero-carbon and smart society”, Huawei Digital Power presented its zero-carbon, all-scenario solution at SNEC 2021. As a leader in the global PV industry, Huawei is contributing towards solar becoming the main energy source in creating a greener world.

One of the most eye-catching parts of the SNEC exhibition was the company’s FusionSolar all-scenario PV & storage solution. It covers “4+1” scenarios: Smart  PV Generator FusionSolar 8.0, Green Residential Power 2.0, Green C&I Power 1.0, and Off-grid (fuel removal) Power Supply Solutions + Energy Cloud, aiming to accelerate the shift to zero-carbon generation and bridge the energy divide.

  • FusionSolar 8.0: Create a Future-proof Smart PV Generator

Disrupting the traditional structure, Huawei launched the future-proof smart PV generator, called FusionSolar 8.0. It offers customers two benefits: First, the smart PV generator promises improved grid stability; second, the world’s first “Gemini” ±1500V design can help to support larger sub-arrays and higher voltages, thus reducing LCOE by 7%.

Specifically, with the ±1500V bipolar string + smart string energy storage solution, the Smart PV Generator features industry-leading DC-coupled architecture and adopts Grid Forming 1.0, an intelligent PV + storage collaborative control algorithm, to enable PV power generation to be grid-connected synchronously and to allow solar power to be stored and controllable. It supports standalone PV systems and enhances power grids. Leveraging the convergence of energy and information flow, the efficient, intelligent and stable Smart PV generator will push PV to become the main renewable energy source.

The world’s first 1500V “bipolar“ string pushes technology boundaries to double system voltage. It supports larger sub-arrays and reduces cable losses, lowering LCOE by 7%.

In addition, Huawei showcased its all-scenario smart string energy storage solution. In traditional energy storage solutions, the difference in battery modules triggers mismatches, resulting in battery capacity degradation, fast attenuation, difficult O&M and high risks. With the integration of digital information, power electronics and energy storage technologies, Huawei leverages the controllability of power electronics to solve the inconsistency of lithium batteries, bringing down LCOS by 20%.

  • Green Residential Power 2.0: Start a New Life in a Zero-carbon Home

The upgraded Green Residential Power 2.0 solution highlights the innovative “1+3+X”structure. With the Smart Energy Controller at its core, it is equipped with three key components— the optimizer, the smart string ESS and the Green Power Cloud to build the intelligent power ecosystem. The Green Residential Power 2.0 solution, focusing on smart power generation, storage and smart power consumption with multiple active safety features, can lower your energy bills and allow you to start a new zero-carbon life.

In terms of smart power consumption, Huawei also released a brand new digital feature – PV, Storage & Consumption AI Synergy. Based on big data learning on weather and user electricity consumption habits, AI can accurately predict future PV power generation and household electricity consumption. Accordingly, it can optimally control the charging and discharging of energy storage under three different scenarios: sunny days, cloudy and rainy days, and smart homes mode. With such technology, it can help to maximize green electricity revenue in each scenario and effectively increase the ratio of self-consumed green electricity. Compared with the 60% pure solar and 85% PV with storage scenarios, the Green Residential Power 2.0 combined with the PV, Storage & Consumption AI Synergy function can now further increase the self-consumption ratio of green power to more than 95%.

  • Green C&I Power 1.0: Let Green Power Empower All Industries

Huawei launched its new C&I solution this year, which fits four different application scenarios: solar only, storage only, solar + storage + charging and off-grid. With the application of optimizers and the smart string energy storage system, the solution can improve energy yield by 30% and energy storage power by up to 15%. Huawei inverters support intelligent AFCI arc protection and automatically shut down within 0.5s, ensuring the active safety of systems.

  • Off-grid (fuel removal) Comprehensive Power Supply Solutions: Green and Inclusive Power Supply to Bridge the Energy Divide

Currently, nearly 900 million people across the globe have no access to grid power or live in areas with an unstable power supply. Diesel generators (DGs) are highly polluting, costly, difficult to maintain and noisy, which seriously affects the normal life of residents and restricts local economic development. Peng Jianhua, President of Huawei’s Site Power Facility Domain, released the series of off-grid (fuel removal) comprehensive power supply solutions, called iPowerCube, which include a full series of M\S\P and can be applied to industrial production and livelihood scenarios. iPowerCube can reduce power generation costs by over 60% and help to promote green development, bridge the energy divide and build a low-carbon society.

  • Energy Cloud: Set up an All-intelligent, Secure and Open Cloud Platform to Break New Ground in the Digital Energy Sector

Benefiting from the Energy Cloud, customers will have access to all-scenario PV and storage power plants. Adhering to the concept of all-scenario refined management, Huawei enables module-level monitoring on the PV side, while allowing pack-level 3D visual management on the storage side. At the same time, the combination of big data analysis and AI intelligent applications (such as intelligent IV diagnosis, SDS intelligent DC power generation system and PV, Storage & Consumption AI Synergy) will allow PV and storage power plants to perform automatically. Huawei is also committed to building a safe and credible digital platform to open data interfaces to a wide range of partners in an effort to break new ground in energy services and achieve win-win cooperation.

  • Huawei’s Digital Power Zero-carbon All-scenario Solution: Leading Power Digitalization for a Zero-carbon and smart society

In addition to zero-carbon power generation, Huawei also displayed its digital power zero-carbon all-scenario solution for the first time at SNEC. In the era of carbon neutrality, Huawei‘s Digital Power business unit gives full play to its strengths in digital technology and power electronics and integrates watt, thermal, energy storage, cloud and AI technology to accelerate the digitization of the energy industry and contribute to a zero-carbon smart society.

Zero-carbon Data Center: Simplified DC allows reshaping architecture through fully prefabricated and modular construction, shortening TTM from 20 months to 6 months. 

Zero-carbon Sites: Huawei provides simplified sites and server rooms and uses all-scenario PV stacking to help 5G operators avoid increased energy-related OPEX, resulting in zero-carbon sites.

Zero-carbon Travel: Focusing on smart electric and smart charging networks, we consistently improve the driving and charging experience, solve safety problems, help EV manufacturers build great cars and help charging station operators build high-quality charging networks to accelerate the electrification of the auto industry.

Charging Networks: The intelligent charging network facilitates the charging of EVs by communicating information among humans, vehicles and charging stations. 

The HiCharger charging module helps charging facility operators improve the operational efficiency of the entire station, reduce annual failure rate, improve charging efficiency and save electricity costs.

Modular Power: The integrated modular power supply fuels industrial upgrading and helps global partners achieve commercial success. 

During the unfolding energy transition, renewables represented by solar PV will inevitably become the primary source of energy, and building a new power system with renewable energy as the main source is the key to achieving carbon neutrality. With enormous expertise in the integration of digital technology and power electronics, Huawei works with customers and partners to promote the energy transition and build a zero-carbon and smart society.
