In the rapidly evolving energy landscape, the integration of large-scale wind power into existing grids presents both opportunities and challenges. A recent study published in ‘Dianli jianshe’ (Electric Power Construction) by a team led by JIN Chu from the Grid Planning Research Center, Guangdong Power Grid Co., Ltd., and LI Zuohong from the State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology, sheds light on a critical aspect of this integration: ensuring frequency safety and optimizing wind energy transfer.
The research, co-authored by LIN Yong, LIU Ruoping, and WEI Fanrong, focuses on the development of a collaborative planning and operation method for wind farms. This method is designed to enhance the frequency security and economic efficiency of large-scale power grid operations. The study introduces an innovative approach that considers the correlation between the outputs of different wind farms, a factor often overlooked in traditional planning methods.
“By constructing an inter-field wind energy transfer model, we can better predict and manage the variability of wind power output,” explains JIN Chu. “This not only improves the utilization rate of wind energy but also ensures the stability of the power grid.”
The study also delves into the system frequency response model of wind turbines, incorporating integrated inertia control and load shedding operation strategies. This ensures that the maximum deviation of system frequency remains within safe limits, a crucial aspect for maintaining grid stability.
The implications of this research are far-reaching. As the energy sector continues to shift towards renewable sources, the ability to efficiently integrate wind power into existing grids becomes paramount. The proposed method could significantly enhance the reliability and efficiency of wind farm operations, making them more commercially viable and attractive to investors.
“Our findings suggest that by carefully planning and operating wind farms with a focus on frequency safety and inter-field wind energy transfer, we can achieve a more stable and efficient power grid,” says LI Zuohong. “This could revolutionize the way we approach wind farm planning and operation, leading to a more sustainable and resilient energy future.”
The study’s application in the IEEE30 node system example demonstrates the practicality and effectiveness of the proposed method. As the energy sector continues to evolve, research like this will be instrumental in shaping future developments, ensuring that wind power can be harnessed to its fullest potential while maintaining the integrity of the power grid.
