Photovoltaic power generation, the system has its own “charging treasure”; With AI “sensing wind”, the prediction accuracy of solar power generation is as high as 90%; Respond to power demand within 1 minute, accurately regulate the balance of supply and demand… In the Xiamen ABB Industrial Center, the “Green microgrid” project built and operated by Xiamen Torch New Source Power Technology Co., LTD. (hereinafter referred to as “Torch New Source”) continuously delivers clean energy to the park and contributes green power to the low-carbon development of Xiamen manufacturing field.

Recently, the “Green microgrid” project was successfully selected into the National Energy Administration’s “List of typical cases of Energy Green low-carbon transformation”, becoming the only project case in Fujian Province that won this “national brand” honor.

T9402 Photovoltaic roof like blue ocean variable large “charging treasure”

Overlooking ABB Xiamen Industrial Center from the air, the large area of solar photovoltaic panels on the roof looks like a blue ocean, and the distributed photovoltaic power generation system provides a steady stream of clean energy for the industrial center.

Jiang Ying, head of digital business at ABB Electric China, said that ABB has set a goal of achieving carbon neutrality in its own operations by 2030, which sets high standards and requirements for the clean power supply, energy management system and energy storage project construction in industrial centers.

At the end of 2020, the ABB team cooperated with Torch New Source to deploy distributed photovoltaic systems in the park, and configure energy storage systems and AC and DC charging pile systems. At the same time, the torch new source also constructs the optical storage direct and soft micro-network in the park, integrating photovoltaic power generation, efficient energy storage, charging and distribution into one, and storing excess electricity. When the external power is tight, the system switches the off-grid mode and turns into a large “charging treasure”, and the discharge guarantees the important load, which not only fully absorbs the photovoltaic power, but also ensures the safety and reliability of the power supply.

T9402 Weather warning, charging pile system, energy storage, virtual power plant… In the smart energy management platform of ABB Industrial Center, the large screen displays the clean energy consumption of the park.

“To achieve more clean energy consumption, it is inseparable from grid integration and coordinated regulation.” Torch New Source company project manager Xie Yinhai said that the project through the deployment of smart energy management platform, “North-South two-way” to achieve docking with a number of heterogeneous systems, can be “south” docking such as photovoltaic system, energy storage system and other information and data, but also “north” docking such as “virtual power plant” platform, power trading platform and other platforms.

The smart energy management platform also uses artificial intelligence and big data to forecast solar and wind power generation through the combination of weather forecasting systems and algorithms, with a prediction accuracy of more than 90%, and holds the “wind and cloud changes” in hand, so as to maximize the consumption and load utilization of clean power generation.

On this basis, the “green microgrid” also aims at the problem of local power supply and demand tension, highly coordinated with Xiamen Power Supply Company, connected to Xiamen’s “virtual power plant” platform, responded to power demand within 1 minute, supported the balance of power supply and demand, and strongly supported the construction of Xiamen’s new power system.

At present, the “green microgrid” can provide about 12.8 million degrees of clean energy for ABB park every year, equivalent to reducing 13,400 tons of carbon emissions, can replace about 50% of the power supply, provide up to 20% of the capacity of the load demand-side response, and become the torch new source to constantly promote energy enterprises to “green” and “low-carbon model”.
