基于参数识别的微电网二次频率自适应控制策略
An adaptive control strategy for microgrid secondary frequency based on parameter identification
摘要
Abstract
Complex microgrid structures and time-varying conditions,among other factors,cause problems in the mechanical modeling of microgrids,making model-based controller optimization difficult.Therefore,this study proposed a secondary frequency adaptive control strategy based on parameter identification,which uses an online parameter identification method to identify the parameters in the microgrid in real-time.The identified parameters are then used in the secondary frequency adaptive controller to optimize the real-time controller performance.The proposed method realizes adaptive optimization of the controller in the microgrid operation state and is applied to a microgrid with unknown parameters to adjust the controller parameters.Finally,a simulation experiment was conducted to verify the model accuracy and the frequency regulation effect of the proposed adaptive control strategy.关键词
