摘要
针对台区传统电压调控速度慢、效率低的现实难题,提出了以电压越限、波动与不平衡综合治理为目标的多时间尺度电压反馈校正控制及其优化策略。首先建立了基于电压灵敏度的台区可调资源优先级评价机制,对电抗器组、储能以及柔性互联装置的电压灵敏度进行推导分析,并考虑多维权重特征,对可调资源的调节优先级进行综合评价。在此基础上,面向台区关键节点,结合所提多场景设备调节方案,从数据输入、电压预测和指令输出三个模块分析了多时间尺度电压反馈校正控制策略。进一步考虑到测量误差及未知扰动的影响,基于最优预测窗口的设计,提出了相应优化策略。
This paper addresses the practical problems of slow speed and low efficiency in traditional voltage regula⁃tion in transformer areas,and proposes a multi⁃time⁃scale voltage feedback correction control and its optimization strategy aimed at the comprehensive management of voltage over⁃limit,fluctuation and imbalance.Firstly,a priori⁃ty evaluation mechanism for adjustable resources in transformer areas based on voltage sensitivity was established.The voltage sensitivity of reactor groups,energy storage,and flexible interconnection devices was derived and ana⁃lyzed.Considering multi⁃dimensional weight characteristics,a comprehensive evaluation of the regulation priority of adjustable resources was conducted.Based on this,for the key nodes of the transformer area,combined with the proposed multi⁃scenario equipment adjustment scheme,the multi⁃time⁃scale voltage feedback correction control strategy was analyzed from three modules:data input,voltage prediction and instruction output.Further considering the influence of measurement errors and unknown disturbances,based on the design of the optimal prediction win⁃dow,corresponding optimization strategies are proposed.
