Rezumat: In ultimii ani, sursele de generare distribuita (GD) au luat o amploare deosebita si se anticipeaza ca in viitor acestea vor avea un rol important in sistemele electroenergetice. O alegere nepotrivita a locului si dimensiunii acestor surse poate conduce la o inrautatire a conditiilor de exploatare referitoare la cresterea nivelului pierderilor de putere activa si scaderea valorilor tensiunilor in noduri, in raport cu situatia in care nu sunt amplasate surse de GD. Obiectivul acestei lucrari este de a gasi locul si numarul optim a surselor de GD folosind tehnicile de clustering in asa fel incat efectele in conducerea si controlul sistemului de distributie sa fie minime. Validitatea metodei propuse este aratata printr-o serie de teste pe retele electrice de distributie.

Cuvinte cheie: surse de generare distribuita, amplasare optimala, tehnici de clustering, retele de distributie


Abstract: Nowadays, the distributed generation (DG) is taking more relevance and it is anticipated that in the future it will have an important role in electric power systems. But, an inappropriate selection of location and size of DG sources can lead to power losses greater than the losses without DG. The objective of the paper is to find the optimal number and placement of DG sources using clustering techniques, so the effects on the operation and control of the distribution system to be minimal. The validity of the proposed method is observed through tests on the different electric distribution networks.

Keywords: DG sources, optimal placement, clustering techniques, distribution networks
