Baowu Clean Energy has applied for a patent for a photovoltaic system control method designed for isolated energy stations in high-altitude regions, enhancing the stability and reliability of power grids. On May 12, 2025, the National Intellectual Property Administration of China published information regarding the application. The patent, titled “Control Method and Device for Photovoltaic System in High-Altitude Isolated Energy Station”, was submitted on January 2025, with the publication number CN119965957A.
The patent abstract reveals that the invention pertains to a control method and device for photovoltaic systems in high-altitude isolated energy stations. These stations comprise a dispatch master station and a photovoltaic system, which is equipped with a photovoltaic fast-response device. This device is responsible for real-time data collection of the photovoltaic system, allowing for power control and regulation based on target data and control commands issued by the dispatch master station.
The dispatch master station is tasked with configuring the control strategy for the photovoltaic system, receiving and processing data uploaded by the fast-response device, and sending control commands back to it. The control method includes several key steps: initializing and configuring the system, activating the photovoltaic fast-response device to perform active power control and voltage control of the photovoltaic station, and operating the dispatch master station’s control strategy according to a preset control mode during the photovoltaic grid-following operating condition.
This close cooperation between the dispatch master station and the photovoltaic fast-response device enables real-time monitoring and precise control of the photovoltaic system, thereby improving the stability and reliability of the power grid.
According to Tianyancha, Baowu Clean Energy Co., Ltd., established in 2019 and based in Shanghai, primarily engages in the manufacturing of chemical raw materials and products. The company has a registered capital of 961,334,492.9 RMB.
