Modelling and Control of Single-Phase Bidirectional AC/DC Converter Used in Microgrid Energy Systems

Öz:
In this study, bidirectional single-phase PWM AC/DC converter that is used in microgrid systems at connection point to the grid, is modelled and controlled. PWM signals of the converter is generated with hysteresis current control technique. The mathematical model is developed in Matlab/Simulink. The converter with 5 kW active power capability is examined in rectifier and inverter mode for steady-state and transient response. Two operation modes of the converter is existed by changing power of the DC load and source. The converter transfers the energy from grid to DC bus in rectifier mode while the energy in the DC bus is transferred to grid in inverter mode. The grid current THD% values meet IEEE 1547 and IEEE 519 standards in both modes with 1.52%. The reactive power support of the converter with phase angle control of the grid current is presented. In both modes, reactive power of 500-900 VAr are provided. The obtained results show the availability of the modelling and control of the converter for active and reactive power generating.

Mikroşebeke Enerji Sistemlerinde Kullanılan Tek Fazlı İki Yönlü AC/DC Dönüştürücünün Modellenmesi ve Kontrolü

Öz:
Bu çalışmada mikroşebeke enerji sistemlerinde şebeke bağlantı noktasında kullanılan iki yönlü tek fazlı PWM AC/DC dönüştürücünün modellemesi ve kontrolü yapılmıştır.Matlab/Simulink ortamında matematiksel model geliştirilmiştir. Dönüştürücü inverter ve doğrultucu modunda 5 kW aktif güç kapasitesinde kararlı hal ve geçici durum cevabı incelenmiştir. Dönüştürücü doğrultucu modunda enerjiyi şebekeden DC baraya doğru gönderirken inverter modunda ise DC baradan şebekeye enerji transferi gerçekleştirmektedir. Şebeke akımı %THD değeri incelendiğinde IEEE 1547 ve IEEE 519 standartları her iki çalışma modunda da %1,52 bozulum oranı karşılanmaktadır. Dönüştürücünün çalışmasında şebeke akımı faz açısı kontrolü ile reaktif güç üretimi de ortaya konmuştur. Elde edilen sonuçlar geliştirilen dönüştürücü modelinin ve kontrolünün dönüştürücü aktif ve reaktif güç üretimindeki uygunluğunu göstermektedir.
