"The experimental platform fully reflects the demand for new energy development in China to achieve the goal of 'dual carbon', the first phase of the design of 161 kinds of photovoltaic and energy storage technology solutions and empirical experiments, rich in content, necessity and practicability, reaching the international leading level." At the recent national photovoltaic and energy storage empirical experimental Platform (Daqing Base) empirical experimental consultation and discussion meeting, the expert group composed of experts and scholars in the domestic photovoltaic and energy storage industry fully affirmed the construction management and data analysis of the first phase of the experimental platform, and unanimously agreed that the data collection, testing and analysis program of the experimental platform is reasonable, and the data is real-time, accurate and practical. It can guarantee the scientificity and impartiality of the experimental platform.

The proposal of the "3060" dual carbon target has ushered in a historical opportunity period for the large-scale development of new energy sources such as photovoltaic, wind power and energy storage in China. The laboratory research level of photovoltaic modules, inverters, energy storage and other key equipment in the industry continues to improve, but the systematic research on the actual operation of outdoor is very lack, resulting in the actual operation performance of many new energy stations that have been built cannot be scientifically and effectively evaluated.

"As the first domestic 'national brand' outdoor empirical experimental platform approved by the National Energy Administration, it will provide measured data for the global photovoltaic industry design, construction, equipment manufacturing, research and development, specification preparation, investment benefit analysis and so on, based on the rich application and experimental scenarios in Daqing." Xiong Minfeng, a member of the Standing Committee of the Daqing Municipal Committee and vice mayor, said that the multi-scene field inspection of the application effect of photovoltaic, energy storage new technologies, new products and new solutions will provide a scientific basis for the large-scale and high-proportion development and utilization of new energy and the national formulation of industrial policies and technical standards.

Pang Xiulan, deputy general manager of the National Power Investment photovoltaic Industry Innovation Center, said that through the monitoring and analysis of environmental factors, power generation, components, brackets, inverter operating characteristics and other data, determine the actual effect of various products and system integration technology in the outdoor, so as to enhance the application of the entire photovoltaic energy storage power station in the power system. Support the construction of a new power system with new energy as the main body. Taking photovoltaic modules as an example, through the measured power generation data of the first year, it can be obtained whether the actual first-year power generation attenuation rate of the module meets the promised value of the manufacturer. If the standard is not reached, the specific reasons can be found by comparing the outdoor measured data and the secondary testing analysis of the laboratory, and ultimately help the manufacturer to improve product performance, improve manufacturing quality and ability.

"The base has installed 657 sets of 20 kinds of online test data equipment in 7 categories such as resources, environment, electrical performance and mechanical performance, and more than 20 sets of offline test devices such as portable IV, infrared test and fault tester. Through real-time data collection and built-in algorithm to analysis software, real-time online analysis and automatic generation of analysis reports are realized to avoid human interference. Ensure fair data analysis." Wang Yang, executive director of Daqing Company of State Power Investment Yellow River Company, said that at present, the experimental platform has developed more than 40 sets of data analysis models, forming more than 150 real-time data analysis reports.

Since 2022, the experimental platform will be based on empirical test results, and simultaneously carry out mechanism analysis of some influencing factors of power generation. In addition to quarterly analysis, empirical data such as components, inverters, brackets, energy storage industry, energy storage system, and energy storage matching and comparison area will be added. Organize white paper conferences on a quarterly and annual basis to publicize the power generation empirical results of various technical products. It is understood that the experimental platform is also equipped with the domestic first-class digital, information, intelligent monitoring system, both centralized control center and data center functions, to achieve the demonstration of real-time data interconnection, real scene interconnection, information interconnection.

During the "14th Five-Year Plan" period, the platform construction management unit - National Power Investment Group Yellow River Upstream Hydropower Development Co., Ltd. will invest about 6 billion yuan to set up four product empirical experimental areas such as photovoltaic modules, inverters, supports, energy storage products, energy storage systems, equipment matching two system empirical experimental areas, planning and layout of about 640 kinds of empirical experimental schemes. In December 2020, the national photovoltaic and energy storage empirical experimental platform was approved by the National Energy Administration; In April 2021, the construction of the platform began; In November 2021, the first phase of the project was completed and put into operation, with 161 layout schemes. In the future, the empirical experiments of various new technologies, new products and new solutions will be added every year to create positive highlights of the industry, and contribute Chinese wisdom, Chinese solutions and Chinese standards to the development of global new energy.
