多虚拟同步发电机独立微网的多目标分布式二次控制方法
Multi-objective Distributed Secondary Control Method for Multi-VSG Independent Microgrid
摘要
Abstract
When a power grid composed of multiple virtual synchronous generators(abbr.VSGs)experiences external dis-turbances,traditional VSG control can lead to issues such as frequency and voltage deviations,low accuracy in reactive power sharing,and active power oscillations,which can easily cause system overload and instability.To address these prob-lems,firstly,the droop characteristics and reasons for power os-cillations of VSGs were analyzed.Secondly,a multi-objective coordinated secondary control strategy was proposed.In this strategy,the consistency frequency restoration control strategy for active power was used to adaptively adjust the reference value of active power to achieve frequency restoration and ac-curate proportional sharing of active power,the consistency and average voltage restoration control strategy for reactive power was used to adaptively compensate for voltage to achieve voltage restoration and accurate proportional sharing of react-ive power.Finally,the effectiveness and robustness of this con-trol strategy are verified through simulation.关键词
