Research on Integrated Inertial Control of Clustered Wind Farm Considering the Wake Effect
In order to solve the problem of the uneven distribution of wind speed caused by wake effect,making it hard for the single-machine equivalent model of wind farm to perform a precise integrat-ed inertial control,an integrated inertial control strategy of wind farm clustering is proposed.This strategy proposes to take the similar frequency regulation capability as the principle of unit clustering,define the frequency regulation capability factor as the clustering index,and dynamically cluster the units by cluste-ring algorithm.The integrated inertial control loop establishes a fuzzy adaptive integrated inertial controller with system frequency deviation and system frequency change rate as inputs,inertial control proportional coefficient and inertial control differential coefficient as outputs so as to realize the integrated inertial con-trol of wind farm clustering.The simulation results show that the proposed clustering index is effective,the established multi-machine equivalent model of wind farm accurately reflects the frequency modulation a-bility of each unit cluster,and the established wind farm clustering integrated inertial control strategy can provide more reliable inertial support.
