2023年第3期23摘要:光伏发电技术的快速发展,带来光伏系统仿真研究的需求。针对目前光伏系统缺乏构网型与跟网型控制的综合仿真研究,及对储能系统功率补偿的依赖程度较高的问题,建立了单相双级型光伏构网与跟网逆变器的仿真模型,设计了无储能的光伏系统控制方法,并在结构一致性的基础上优化光伏系统控制结构。通过在MATLAB/Simulink软件中对所设计的光伏构网与跟网系统进行模拟仿真,验证了控制方法的有效性。关键词:单相双级型光伏系统构网控制跟网控制逆变器设计中图分类号:TM359文献标志码:ADOI编码:10.3969/j.issn.1006-2807.2023.03.006Abstract:Therapiddevelopmentofphotovoltaic(PV)powergenerationtechnologybringsthedemandinthefieldofPVsystemsimulationresearch.Inviewofthelackofcomprehensivesimulationresearchongrid-constructing&grid-followingcontrolofPVsystemaswellastheproblemofhighdependenceonpowercompensationofenergystor-agesystem,thesimulationmodelofsingle-phasetwo-stagePVgrid-constructingandgrid-followinginverterisestab-lished,thecontrolmethodofPVsystemwithoutenergystorageisdesignedandthecontrolstructureofPVsystemisoptimizedonthebasisofstructuralconsistency.Theeffec-tivenessofthecontrolmethodisverifiedbysimulatingthedesignedPVgrid-constructingandgrid-followingsystembymeansoftheMATLAB/Simulinksoftware.Keywords:single-phasetwo-stagephotovoltaicsystemgrid-constructingcontrolgrid-followingcontrolinverterdesign单相双级型光伏构网与跟网逆变器仿真设计冯文波1范铮2伊比益1朱凯翔1郑太英21.浙江华云电力工程设计咨询有限公司(310016)2.浙江大学(310027)SimulationDesignofSingle-phaseTwo-stagePhotovoltaicGrid-constructingandGrid-followingInverterFENGWenbo1FANZheng2YIBiyi1ZHUKaixiang1ZHENGTaiying21.ZhejiangHuayunElectricPowerEngineeringDesign&ConsultationCo.,Ltd.(310016)2.ZhejiangUniversity(310027)随着光伏、风电等新能源发电技术的快速发展,新能源电站的数量和容量均有所提升,电力系统中的新能源渗透率增加,使系统结构与控制性能均出现重大变革。光伏系统引入传统电网将带来稳定性下降、调频惯量丢失、逆变器等效电源形式冲突和保护设定等诸多问题,亟须通过数学方法、仿真建模以及实物实验等方式予以解决。其中,仿真建模研究既能...
