Following the deregulation of electric power utilities around the globe, it has been widely acknowledged that quantifying the power transfer capability is of increasing importance in the operation and planning of interconnected power systems. This paper reports on the application of probabilistic distribution based interval arithmetic method to estimate the Available Transfer Capability (ATC) i...

in this paper, load and buckling mode of a smart column are presented. the theoretical model is a three-layer piezoelectric composite beam that behaves as an axial actuating mechanism. this actuator consists of an elastic core sandwiched between two piezoelectric active outer layers. the piezoelectric layers are polarized transversely, i.e., the polarization vector is parallel to the applied el...

Electric power systems are the structures that have the purpose of generating, transporting and distributing electricity. These structures are composed of energy generating plants, transmission lines, distribution systems and elevating and distribution substations. The biggest challenge of this type of system is that the electrical energy is not a material that can be stored. That is, so it is ...

The rise of electric vehicles brings a number of challenges for our infrastructure and energy security. Waraich (Waraich et al., 2009) demonstrates that bad choices of charging times made by the owners of electric vehicles (EVs) or plug-in hybrid electric vehicles (PHEVs) can lead to severe problems for the electric grid due to peak loads. Coordinated charging decisions controlled by a centrali...

Loads estimation is becoming each time more fundamental for an efficient management and planning of electric distribution systems. Among the factors that contribute to this need of more efficiency are the increasing complexity of these networks, the deregulation process and the competition in an open energy market, and environment preservation requirements. However, the only information general...

Prediction of peak loads in Iran up to year 2011 is discussed using the Radial Basis Function Networks (RBFNs). In this study, total system load forecast reflecting the current and future trends is carried out for global grid of Iran. Predictions were done for target years 2007 to 2011 respectively. Unlike short-term load forecasting, long-term load forecasting is mainly affected by economy...
