In this study, a simulation of a standalone photovoltaic system with a power of 4.2 kW was carried out. In the system, which has a total of 20 photovoltaic panels, the perturb & observe maximum power point tracking method was used, and photovoltaic panel control was performed by a DC-DC boost converter. Thus, maximum power could be drawn from the panels continuously despite changing weather conditions. Batteries are used to store energy in this system, which operates independently from the network. The battery group with a total voltage level of 300V was charged and discharged by a bidirectional DC-DC converter. With variable radiation values, variable power generation was provided in the panels, and energy flow control in the system was realized. The required energy flow in the system has been controlled depending on the amount of energy generated from the photovoltaic panels, the energy demanded by the load and the state of charge of the battery pack. The energy in the dc bus regulated at 400V voltage level fed the load with the help of a single-phase inverter. The system was operated in five different modes, and performance of the system was introduced. |

Bu çalışmada 4,2 kW gücünde şebekeden bağımsız bir fotovoltaik sistemin simülasyonu gerçekleştirilmiştir. Toplamda 20 adet fotovoltaik panel bulunan sistemde değiştir-gözle maksimum güç noktası takibi yöntemi kullanılmış ve yükseltici DC-DC dönüştürücü ile fotovoltaik panel kontrolü yapılmıştır. Böylece değişen hava şartlarına karşın sürekli olarak panellerden maksimum güç çekilebilmiştir. Şebekeden bağımsız olarak çalışan bu sistemde enerjinin depolanması için bataryalar kullanılmıştır. Toplam 300V gerilim seviyesi sahip batarya grubu iki yönlü DC-DC dönüştürücü ile şarj ve deşarj edilmiştir. Değişken sıcaklık değerleri ile panellerde değişken güç üretimi sağlanmış ve sistemde enerji akışı kontrolü gerçekleştirilebilmiştir. Fotovoltaik panellerden üretilen enerji miktarı, yükün talep ettiği enerji miktarı ve akü grubu şarj durumuna bağlı olarak sistemde gerekli enerji akışı kontrol edilmiştir. 400V gerilim seviyesinde regülasyonu yapılan dc baradaki enerji tek fazlı inverter yardımı ile yükü beslemiştir. Sistem beş farklı çalışma modunda çalıştırılmış ve sistemin performansı ortaya konmuştur. |
