Hi Naki! Thank you very much for making such useful videos on PV system. However, I wish you could make a video of complete PV system, i.e. right from starting with solar panels, then Boost Converter, then MPPT, then 3 phase inverter, then transformer and finally the grid. I need complete design and Simulation Sir. Plz Plz Plz help me!!!

Hi Naki, you see the inverter voltage is more than 500Vac. Isn't like to be 310V for our grid. Also the PV voltage is more than 900V. Isn't like to be 812V in this arrangement? Please answer.
@nakiguler
@nakiguler 4 года назад
It is phase to phase voltage. why the dc voltage should be 812V? DC bus voltage is not controlled here.

@nakiguler
@nakiguler 5 лет назад
Did you try to change 380 to 415 in reference voltage? So, the reference voltage should be 415*sqrt(2). You should change the load voltages. You may need to change PI parameters. But, please try to changes step by step.

İyi günler, söylediğiniz durumlar için temel bir yönetim algoritması gerekli. Burada birçok parametreyi göz önünde bulundurmanız gerekebilir, rüzgar üretimi var mı, güneş var mı, bataryalar boş mu dolu mu..... diye gider. Çok karmaşık bir yapı çıkar ki kontrolü de ayrı bir beladır maalesef. Eğer bunları oluşturma yöntemi soruyorsanız, matlab function bloğu var kod yazılabiliyor o daha kolay olacaktır. Kolaylıklar dilerim.

@@nakiguler Dediğiniz gibi hocam ödevde senaryolar oluşturdum. Senaryo 1: Üretilen enerji tüketimden fazla ise depolama birimine fazla elektrik enerjisi gönderilerek depolanır. Senaryo 2: Tüketimin üretimden fazla olduğu zamanlarda hibrit sistemle üretilen ve depolanan elektriğin birlikte tüketiciye elektrik verilerek enerji sürekliliği sağlanmış olur. Senaryo 3: Tüketimin puant saat zamanında üretimin tüketimi karşılamadığı zamanlarda depolanan enerji ve üretilen enerjiden tüketicinin elektrik ihtiyacı karşılanmış olur. Senaryo 4: Hibrit enerji sistemleri bileşenlerinden rüzgarın veya güneşin olmadığı zamanlarda tüketicinin enerji ihtiyacı sistemin ürettiği elektrikten fazla ise depolanan enerjiden ve sistemden üretilen enerjiden karşılanmaya çalışılır. Senaryo 5: Hibrit enerji sistemleri bileşenlerinden rüzgarın veya güneşin olmadığı zamanlarda tüketicinin enerji ihtiyacı sistemin ürettiği elektrikten az ise sadece üretilen enerjiden karşılanmaya çalışılır. Bir diğer kontrol birimi olan akülerde, Akülerin şarj ve deşarj durumlarına bakılarak: Akülerin aşırı şarj ve deşarj olması engellenecektir. Akülerin güvenli çalışma bölgesinde çalışması sağlanacaktır. ödevim bu şekilde Naki hocam sizden ricam bununla ilğili bir video paylaşabilir misiniz? matlapla ilğili bilğim çok az. Yardımınız için çok teşekkür ederim.
