The country's first low-carbon virtual power plant precision response was successfully implemented in Lingang New Area
"We responded twice in the morning and evening, reducing carbon emissions by 1.047 tons. Although the amount of carbon reduction is not large, it has truly achieved the full consumption of local clean energy and precise carbon emission reduction in electricity. This is a brand-new innovation in the construction process of our new power system. Explore and practice," said Xie Bangpeng, chief data engineer of State Grid Shanghai Pudong Power Supply Company.
On June 6, the country’s first low-carbon virtual power plant precise response was successfully implemented in the Lingang New Area. This response aims to maximize the consumption of local clean energy by monitoring the dynamic changes in power carbon emission factors in real time. It guides users to use less high-carbon electricity when clean energy power generation is low, and guides users to use more low-carbon electricity when clean energy power generation peaks. electricity and promote regional green, low-carbon and high-quality development.
At 8:15 on June 6, the Pudong New Area Electric Load Management Center system showed that the dynamic power carbon emission factor change in the Lingang area was 0.3944 tons/MWh, which was at a high level. As a result, the staff sent out "peak reduction" invitations to 60 users to respond to the invitation. In the final assembly workshop of SAIC Motor Passenger Car Company's Lingang base, on-site staff performed production line adjustments through the digital factory system, and the two production lines slowly stopped operating. "We received an invitation to a virtual power plant yesterday and hope to reduce the load this morning when the output of new energy sources is low." Huang Songwei, head of energy management at the plant, said, "This is in line with our active promotion of carbon reduction throughout the product life cycle and the creation of a zero-emission power plant. The goals of the Carbon Automotive Industrial Park coincide with each other.”
At 21:30 that night, wind power generation in the Lingang area increased significantly, and the power carbon emission factor also dropped to 0.3165 tons/MWh. 46 users responded to the "valley filling" invitation. In the central control room of the "wind, solar, storage and charging" integrated microgrid on the Lingang campus of Shanghai Electric Power University, staff conducted inspections on a set of 340 kW/680 kWh new energy storage devices through the smart energy management and control system according to the virtual power plant control instructions. Charging operation stores "low-carbon electricity" for use the next day.
A virtual power plant is not a physical power plant, but an integrated system that aggregates, coordinates and optimizes distributed energy resources scattered throughout the country through advanced information communication technology and software systems. The virtual power plant manages these resources in a unified manner to form a dispatchable and controllable energy aggregation. The power carbon emission factor refers to the carbon content per kilowatt-hour of electricity, which can directly reflect the power generation of clean energy such as solar energy and wind energy. The higher the value, the higher the carbon content per kilowatt-hour of electricity, which means the greater the amount of clean energy power generation. few.
"This time the precise response of the virtual power plant driven by low-carbon electricity consumption is a concrete realization of technological innovation driving production practice, which is of great significance." Li Qifen, director of the Scientific Research Office of Shanghai Electric Power University, said: "In the preliminary work, we and The government and the power grid worked closely together to carry out Lingang local new energy output forecast based on the operation of the Lingang regional power grid, which provided scientific certification for the implementation of the precise response of this low-carbon virtual power plant. At the same time, our Shanghai Electric Power University also featured energy and power. It will be implemented locally in Lingang, and the new energy storage, charging piles and other adjustable loads on the campus will be actively used to participate in this response and contribute to the smart, low-carbon and resilient development of the Lingang New Area.”
"We are actively leveraging the role of Lingang New Area as a 'growth pole', 'test field' and 'accelerator' to explore diversified innovative applications of virtual power plants and use this to promote strategic emerging industries such as energy storage, hydrogen energy and new energy vehicles. development," said Xi Xiaobin, deputy director of the Development and Reform Department of the Lingang New Area Management Committee.
"This response is also a 'wartime' drill for the peak of summer. Our load management centers at the city and district levels have linked up and worked closely together to successfully realize the first district-level 'unified organization at the municipal level and customized application at the regional level' in the city. The flexible scheduling of virtual power plants has taken a solid step forward in new scenarios, new applications, and new models of virtual power plants," said Zheng Qingrong, director of the Demand Side Management Center of the State Grid Shanghai Electric Power Company's Operation Service Center.
Based on previous cooperation with Tsinghua University, Shanghai Electric Power University and other universities, State Grid Shanghai Pudong Power Supply Company planned and implemented this low-carbon virtual power plant to accurately respond to dynamic changes in power carbon emission factors. After the accurate response of this virtual power plant is completed, Pudong Power Supply Company will also carry out the first domestic carbon reduction benefit assessment of regional virtual power plants based on dynamic power carbon emission accounting.
