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。

This paper investigates a microgrid generation system with wind-solar complementarity.To address the mismatch between 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 implemented 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 approach are demonstrated through the construction and validation of a simulation model in MATLAB/Simulink.
