摘　　要：针对虚拟同步发电机VSG(virtual synchronous generator)自适应控制大范围调节参数导致需要较大储能容量配置的问题,设计ln基底型自适应控制策略以优化储能容量配置。通过对基于速度反馈控制的虚拟同步发电机VF-VSG(velocity feedback control based VSG)进行数学建模,建立VSG在输入功率扰动时与所需储能容量之间的关系,据此分析速度反馈系数、VSG转动惯量和阻尼系数对储能容量的影响,以此设计ln基底型自适应控制策略,避免参数大范围调节,优化储能容量配置。通过仿真实验可知:所提控制策略在暂态性能优良的前提下,降低了9.8%储能容量的配置,验证了所提策略的有效性。To address the problem that the adaptive control of a virtual synchronous generator(VSG)requires a large energy storage capacity configuration due to a wide range of adjustment parameters,a natural-log-type adaptive control strategy is designed to optimize the energy storage capacity configuration.Through the mathematical modeling of VSG based on the velocity feedback control(VF-VSG),the relationship between the VSG and the required energy storage capacity under input power disturbance is established,and the effects of velocity feedback coefficient,VSG rotational inertia and damping coefficient on the energy storage capacity are analyzed accordingly.On this basis,the natural-logtype adaptive control strategy is designed,under which the wide range of parameter adjustment is avoided and the ener⁃gy storage capacity configuration is optimized.Through simulation experiments,it can be seen that the proposed control strategy can reduce the configuration of energy storage capacity by 9.8%with an excellent transient performance,which verifies the effectiveness of the novel strategy.
