Islanding feasibility considering reactive power in the subtransmission systems

Nowadays, the penetration of Renewable Energy Sources (RES) in electrical networks is growing significantly. In spite of many problems it introduces, the connection of RES in the subtransmission systems also gives the opportunity of exploiting them for the benefit of the network. In this paper, this is done for islanding conditions and a Genetic Algorithm (GA) based procedure to make a stable islanded operation is proposed. The results are evaluated successfully by tests carried out on a real system.
