频率时空差异下考虑功率波动的新能源主动调频优化方法
An optimization method for active frequency regulation of renewable energy account-ing for power fluctuations under spatiotemporal differences
摘要
Abstract
The power fluctuations of renewable energy sources(RES)adversely affect their frequency regulation per-formance when participating in active frequency response(AFR),while current assessment methods for RES fre-quency regulation capability remain inadequate.To address these challenges,this paper proposes an optimized AFR approach for RES based on distributed model predictive control(DMPC).The proposed method employs Tube-based model predictive control(MPC)for RES units within fault-affected areas,while utilizing robust control bar-rier functions(RCBF)to constrain the control parameters of RES in non-fault zones.This integrated approach estab-lishes an improved distributed MPC framework that ensures both conventional units and RES units can effectively perform AFR amidst renewable power fluctuations.Furthermore,the method determines the optimal load-shedding rate for RES to maintain sufficient power reserve and frequency regulation capacity,thereby formulating an execut-able AFR strategy.This approach enables practical implementation of RES-based AFR control.Simulation studies on an interconnected power system with high renewable penetration demonstrate that the proposed method signifi-cantly enhances the AFR capability of renewable energy sources.关键词
