Recently, the Wuhu independent energy storage power station project located in Wuhu City, Anhui Province was officially connected to the grid. SPRIXIN provided primary frequency modulation system services for it, and continued to follow up and debug the application performance to assist the energy storage power station in dynamically ensuring the power grid's active power balance. Improve the stability of grid-connected operation of energy storage power stations.
Primary frequency regulation refers to the service provided by conventional units through the automatic response of the speed regulation system, and by grid-connected entities such as new energy and energy storage through rapid frequency response, when the power system frequency deviates from the industrial frequency, the active power output is adjusted to reduce the frequency deviation.
As the proportion of new energy installed capacity increases, the requirements for "primary frequency regulation" for wind power and photovoltaic power plants are also increasing. In order to alleviate the frequency regulation pressure, domestically, from the five northwest provinces (Shaanxi, Gansu, Qinghai, Ningxia, Xinjiang) to the five provinces under the jurisdiction of the Southern Power Grid (Yunnan, Guizhou, Hainan, Guangdong, Guangxi), including Hubei and Hunan, many places, Relevant policy documents have been issued, requiring existing wind farms and photovoltaic power stations to undergo primary frequency regulation transformation, and new power stations put into operation must have primary frequency regulation functions.
The importance of primary frequency regulation for energy storage power stations and new energy stations cannot be ignored. In the power system, primary frequency regulation technology not only ensures the safe and stable operation of energy storage power stations and new energy stations, but also provides strong support for the reliable operation of the power system. For energy storage power stations, it can use stored electrical energy to adjust the frequency of the power grid to achieve stable support for the power system. Especially when faced with frequent fluctuations in the power grid or sudden load surges and falls, energy storage power stations can respond quickly and store or release electric energy quickly, thereby reducing the burden on the power system. Similarly, when new energy stations face the volatility and uncontrollability of new energy power generation, they also need to adjust the power generation to coordinate the power balance of the power grid and protect the power grid from being affected by new energy power.
At present, SPRIXIN has passed product function and safety test tests in Yunnan, Jiangsu, Zhejiang, Shandong, Hunan, and other regions, including China Electric Power Research Institute and State Grid Electric Power Research Institute, and various performance tests have shown strong stability sex. SPRIXIN's primary frequency modulation technology products have also been successfully applied in many provinces and cities across the country. It can provide primary frequency modulation technology services for booster stations, wind power/wind storage, wind and solar complementary/wind and solar storage, photovoltaic/solar storage, energy storage, and other scenarios.
