Abstract

The purpose of this research is to model and simulate 100 kW solar PV systems that are connected to the utility distribution system with and without Distribution Static Synchronous Compensator (D-STATCOM) and Dynamic Voltage Restorer (DVR) under normal and faults condition in MATLAB/ Simulink. The test systems consist of a PV array that is connected in series and parallel modules, a DC-DC Boost Converter, Maximum Power Point Tracking (MPPT) control, DC-AC inverter, inverter control, filter, three-phase load, distribution transformer, and grid equipment. The grid operates test systems at the nominal three-phase line to line voltage of 260 V, supplied from 100 kVA 25/0.26 kV distribution transformer. The simulation results showed that the installation of D-STATCOM and DVR in GCPV systems improved 80-90% of the output power from the PV systems. The implementation of D-FACTS devices in GCPV systems will be beneficial for future power system stability studies in the distribution system.

基于D-STATCOM的并网太阳能光伏(GCPV)系统建模提高系统稳定性

本研究的目的是在MATLAB/ Simulink中对100 kW的太阳能光伏系统在正常和故障情况下进行建模和仿真，该系统与公用事业配电系统连接，有和没有配电静态同步补偿器(D-STATCOM)和动态电压恢复器(DVR)。测试系统由串联和并联模块连接的光伏阵列、DC-DC升压变换器、最大功率点跟踪(MPPT)控制、DC-AC逆变器、逆变器控制、滤波器、三相负载、配电变压器和电网设备组成。电网运行测试系统的标称三相线对线电压为260 V，由100 kVA 25/0.26 kV配电变压器供电。仿真结果表明，在GCPV系统中安装D-STATCOM和DVR可使光伏系统输出功率提高80-90%。D-FACTS装置在GCPV系统中的应用将有利于今后配电系统稳定性的研究。
