Grid constrained probabilistic reliability evaluation of power systems including wind turbine generator

This paper proposes a new methodology for evaluating the probabilistic reliability of grid constrained composite power system including the WTG. The proposed model can consider capacity limitation and forced outage rate of transmission line. The importance of renewable energy sources has been growing at a high rate as a result of being environment friendly. In particular, wind energy is one of the most successfully utilized of such sources to produce electrical energy. Because of the randomness of wind speed, however, the multi-state model is suited for modeling wind turbine generators(WTG). A simple case study using two buses system shows in detail how it is used to perform a reliability evaluation study in proposed model.
