Research on New Energy Grid Adaptation Based on Grid Frequency Correction Strategy
Under the constraint of power balance,the proportion of new energy access continues to increase,the adjustment range of distribution network operation mode is expanding,and the risk of failure of conventional grid frequency correction strategy control is gradually increasing.Based on this,a typical new energy distribution network system was constructed,and a description method of the power grid operation scenario domain for studying frequency correction strategies was provided.The multi round adaptation of the frequency correction strategy control system to the power grid operation scenario domain was calculated,and the setting interval of the control quantity was used as the evaluation index for adaptation.The minimum setting interval was used to evaluate the adaptability of the frequency correction control system.Finally,a case study was conducted.Based on the actual parameters of the distribution network,an analysis model was constructed to calculate the maximum proportion of new energy access that the frequency correction control system meets under adaptive conditions.
