Robust Primary Frequency Reserve Optimization for Renewable Energy Power Systems

During the operation of the power system, the uncertainty of the natural resources conditions will cause the deviation of the actual frequency support capacity of renewable power generation deviates from the expected value, which will affect the post-disturbance frequency stability. This paper studies the robust setting of primary frequency modulation backup of renewable energy power systems considering the uncertainty of wind and solar power generation. Considering the influence of the uncertainty of wind and solar power generation on the frequency regulation backup, a robust tuning model of the primary frequency regulation frequency backup of the renewable energy power system is established. In the sufficiency verification stage, the sufficiency of the primary frequency modulation reserve in extreme wind and solar power generation scenarios is analyzed, and the column and constraint generation algorithm is used to solve the problem. Finally, the validity of the model is verified in the improved IEEE 39-bus system.
