光伏系统中虚拟惯性与阻尼增益协调控制策略
Virtual inertia and damping gain coordinated control strategy in photovoltaic systems
摘要
Abstract
With the rapid penetration of new energy sources such as photovoltaic power generation,the power system has put forward higher requirements for its participation in primary frequency regulation,requiring it to support the power grid in a more flexible way.In order to achieve more comprehensive frequency regulation,the key indicators for evaluating frequency quality are first determined according to the relevant grid specifications.Then,with the help of the motion equation of synchronous generator rotor,the effects of the constant of inertia and damping gain on the frequency quality are analyzed.Based on these research results,a coordinated control strategy of virtual inertia and frequency damping is designed,aiming to achieve the optimal frequency support of photovoltaic system with a certain power reserve.Finally,the performance of the proposed control strategy is verified by simulation,and the advantages and effectiveness of PV system participating in primary frequency regulation are displayed.By coordinating between virtual inertial control and frequency damping control,photovoltaic systems can support the frequency stability of the grid in an efficient manner.关键词
