摘要
对风光储互补的微电网发电系统进行研究,针对风光发电与负载功率不匹配问题,提出了一种基于新型变步长电导增量法的最大功率点追踪控制方法,利用基于Ziegler-Nichols法的改进自适应PID算法实现负载功率蓄电池充放电控制的协同控制策略.通过在MATLAB/Simulink中搭建仿真模型并进行验证,证明了所述方案的准确性以及可行性.
Abstract
This paper investigates a microgrid generation system with wind-solar complementarity.To address the mismatch be-tween wind-solar generation and load power,a novel variable step-size conductance increment method for maximum power point tracking control is proposed.Additionally,a collaborative control strategy for load power battery charge and discharge is imple-mented using an improved adaptive PID algorithm based on the Ziegler-Nichols method.The work is described in the past tense,detailing the research,and the conclusions are presented in the present tense.The accuracy and feasibility of the proposed ap-proach are demonstrated through the construction and validation of a simulation model in MATLAB/Simulink.
