Recently in the Hexi Corridor, a wind turbine blade rotates against the wind, and rows of photovoltaic panels are neatly arranged. Continuous green electricity flows into the power grid. In the wind-solar-storage grid-connected operation and empirical experimentation room of the State Grid Gansu Electric Power Research Institute in Lanzhou, Gansu Province, the institute's technicians use the "Grid-Connected Performance Detection and Analysis Platform Based on Artificial Intelligence for New Energy Base in Desert, Gobi and Desert Areas" to assess the grid-connected performance of wind power and photovoltaic power generation projects. The real-time updated various calculation and analysis data on the display screen reflect the entire process of the grid-connected performance test analysis of the new energy station.

作为全国重要的新能源生产基地与“西电东送”战略通道，甘肃沙漠戈壁荒漠地区新能源项目连片开发，新能源场站密集并网，新能源发电装机规模占电源总装机规模的比例超64%，新能源已成为甘肃电网第一大电源。如何让具有波动性、间歇性特点的绿电并得稳、送得出、用得好，成为新型电力系统建设的核心课题。

As an important national base for new energy production and a strategic channel for "power transmission from the west to the east", the new energy projects in the desert, gobi and arid areas of Gansu Province have been developed in contiguous blocks. New energy power stations are densely connected to the grid, and the installed capacity of new energy power generation accounts for over 64% of the total installed capacity of power sources. New energy has become the largest power source in the Gansu power grid. How to ensure the stability, transmission and optimal utilization of green electricity with its fluctuating and intermittent characteristics has become a core issue in the construction of the new power system.

规避人工错判风险

Avoid the risk of human error in judgment

新能源场站大规模接入电网后，保障电网安全稳定运行是重中之重。以往，新能源场站并网前主要依靠第三方机构出具纸面测试报告，审核测试报告环节需开展大量的数据对比分析。传统人工审核模式下，审核人员可能难以发现数据修改、结论美化等较为隐蔽的不合规行为，降低审核准确性。为杜绝新能源场站“带病入网”，2025年2月起，国网甘肃电科院针对沙戈荒新能源基地开始研发并网性能检测分析平台。

After large-scale integration of new energy power stations into the power grid, ensuring the safe and stable operation of the power grid has become the top priority. In the past, before new energy power stations were connected to the grid, they mainly relied on paper-based test reports issued by third-party institutions. The review of these test reports required a lot of data comparison and analysis. Under the traditional manual review mode, reviewers might have difficulty detecting more concealed non-compliant behaviors such as data modification and conclusion embellishment, thereby reducing the accuracy of the review. To prevent new energy power stations from "entering the grid with diseases", starting from February 2025, the Gansu Electric Power Research Institute of State Grid began to develop a grid connection performance detection and analysis platform for the Shagaoquan New Energy Base.

研发团队直接从底层测试环节入手，抽取硬件级数据，第一时间抓取新能源场站最原始的涉网测试表现数据并加密回传。并网性能检测分析平台基于底层数据开展真值报告重构，计算生成反映新能源场站实际运行情况的检测报告。审核人员利用该平台生成的报告与第三方机构提供的报告进行交叉比对，能够准确迅速发现隐患。

The R&D team started from the bottom-level testing stage, extracted hardware-level data, and immediately captured the most original grid-connected test performance data of the new energy power station and encrypted it for real-time transmission. The grid connection performance detection and analysis platform based on the underlying data re-constructed the true value report, and calculated and generated detection reports reflecting the actual operation status of the new energy power station. The reviewers used the reports generated by this platform and compared them with the reports provided by third-party institutions to accurately and quickly identify potential risks.

“以前人工审核检测报告比较费时。现在用了并网性能检测分析平台，核查速度快多了。它能帮我发现一些容易被漏掉的问题，规避了人工漏判、错判风险。”国网甘肃电科院新能源技术研究所技术人员张睿骁介绍。该平台通过云边协同实现数据轻量化处理，将数据体量压缩至原始大小的10%—20%，解决了海量高频数据传输难题，全面提升新能源场站并网监管水平。

"Previously, manual review of test reports was quite time-consuming. Now, with the grid performance detection and analysis platform, the verification process has become much faster. It helps me identify some issues that might otherwise be overlooked, avoiding the risks of human misjudgment or error. " Zhang Ruixiao, a technician from the New Energy Technology Research Institute of Gansu Electric Power Research Institute, explained. This platform achieves lightweight data processing through cloud-edge collaboration, reducing the data volume to 10% - 20% of its original size. It has solved the problem of transmitting massive and frequent data, significantly improving the grid connection supervision level of new energy power stations."

3月，“基于人工智能的沙戈荒新能源基地并网性能检测分析平台”项目入选由金砖国家工业创新大赛组委会编制的《2025金砖国家工业创新大赛优秀项目集》，为全国沙戈荒新能源基地安全并网提供可复制、可推广的方案。

In March, the "AI-based Performance Detection and Analysis Platform for Grid Connection of Shagaoqiao New Energy Base" project was selected for inclusion in the "2025 BRICS Industrial Innovation Competition Outstanding Project Collection" compiled by the BRICS Industrial Innovation Competition Organizing Committee. This provides a replicable and scalable solution for the safe grid connection of all sandbar and desert wind and solar energy bases across the country.

精准分析宽频振荡成因

Precisely analyze the causes of wideband oscillation

新能源电力发得出，更要稳得住。大规模接入电网后，风电机组、光伏发电逆变器等电力电子设备易导致电网发生宽频振荡。在国网甘肃省电力公司新型电力系统仿真中心，技术人员操作电力系统全数字实时仿真新能源阻抗分析平台，对风电机组开展多工况扫频仿真。该平台可在不同发电负荷、电网电压、运行模式等情况下，全面扫描风电机组的电气阻抗特性，精准找到风电机组与电网易发生共振的危险频率点，再通过参数优化、控制策略调整等方式，避开或消除危险点，从根本上避免宽频振荡发生。

Renewable energy power generation is possible, but it must also be stable. After large-scale integration into the power grid, power electronic devices such as wind turbine generators and photovoltaic inverter systems are prone to cause wide-band oscillations in the power grid. At the new power system simulation center of the State Grid Gansu Electric Power Company, technicians operate the full-digital real-time simulation platform for the power system and the new energy impedance analysis, conducting multi-condition swept-frequency simulations on wind turbine generators. This platform can comprehensively scan the electrical impedance characteristics of wind turbine generators under different power generation loads, grid voltages, operation modes, etc., accurately identifying the dangerous frequency points where wind turbine generators are prone to resonance with the grid. Then, through parameter optimization and control strategy adjustments, these dangerous points can be avoided or eliminated, fundamentally preventing the occurrence of wide-band oscillations.

“我们依托电力系统全数字实时仿真新能源阻抗分析平台，创新验证了多参数协调优化的阻抗重塑振荡抑制方法。”国网甘肃电科院电力系统研究所技术人员张旭军说，“这种方式解决了新能源场站并网后导致的宽频振荡原因分析难的问题。”

"We relied on the fully digital real-time simulation platform for the power system and the new energy impedance analysis to innovatively verify the impedance reshaping and oscillation suppression method that coordinates multiple parameters for optimization," said Zhang Xujun, a technician from the Power System Research Institute of Gansu Electric Power Research Institute of State Grid. "This approach has solved the problem of difficult analysis of wide-band oscillations caused by the grid connection of new energy power stations."
