Simulation of Peak and Frequency Modulation of Double-fed Wind Turbine Group Considering Multiple Uncertainty Risks
Under the combined effect of multiple uncertain risk factors,the peak shaving and frequency reg-ulation effect of wind turbine groups deviates significantly from the expected effect,increasing the difficulty of operation.To solve this problem,a simulation method for peak shaving and frequency modulation hybrid control of doubly fed wind turbine groups was proposed.Established a multi uncertainty risk model for a dou-bly fed wind turbine group,evaluated the output confidence of the wind turbine group under multiple uncer-tainty risks,established a mathematical model for the control of a doubly fed risk turbine group,and imple-mented a hybrid control strategy for peak shaving and frequency regulation.By analyzing and optimizing the correlation between global parameters and variables in the control process,the hybrid control effect of peak shaving and frequency modulation can be achieved.The test results indicate that the variance weight is al-ways less than or equal to 1.Prove that the method proposed in this article can effectively improve the accu-racy and stability of peak shaving and frequency regulation control of wind turbine groups under uncertainty risks,and has good application value.
