This paper describes a probabilistic approach for assessing the criticality of bulk transmission system components in the de-regulated electricity market. The proposed method is based on the analysis performed by the Hydro One probabilistic composite system evaluation program and use of a simplified reliability model for the transmission system network. The method accounts for random failures of system...
DC-link type wind turbine generating systems are expected to be increasingly used because they can be operated for a wide range of wind velocity with relatively high efficiency. So far, voltage-source PWM inverters are exclusively used for this type of system to convert generated power to AC power with constant voltage and frequency. However, for the cases to enlarge power ratings of the system drawbacks...
This paper illustrates a new fuzzy effective load model for probabilistic and fuzzy production cost simulation of the load point of the composite power system. A model for reliability evaluation of transmission system using fuzzy set theory is proposed for considering the flexibility or ambiguity of capacity limitation and over load of transmission lines which is subjective matter characteristics...
