a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

This paper describes the development of a connectionist-hidden Markov model (HMM) system for the 1997 DARPA Hub-4E CSR evaluations. We describe both system development and the enhancements designed to improve performance on broadcast news data. Both multilayer perceptron (MLP) and recurrent neural network acoustic models have been investigated. We assess the effect of using gender-dependent aco...

Colicins are protein antibiotics produced by Escherichia coli to kill closely related non-identical competing species. They have taken advantage of the promiscuity of several proteins in the cell envelope for entry into the bacterial cell. The Tol-Pal system comprises one such ensemble of periplasmic and membrane-associated interacting proteins that links the IM (inner membrane) and OM (outer m...

One main group of a transportation network is a discrete hub covering problem that seeks to minimize the total transportation cost. This paper presents a multi-product and multi-mode hub covering model, in which the transportation time depends on travelling mode between each pair of hubs. Indeed, the nature of products is considered different and hub capacity constraint is also applied. Due to ...

Energy-consuming countries are affected by obstructions in supplies or conflicts that may occur along the energy transit path. Hence, presence of a global logistics hub for acting as connecting bridge between energy-supplying and energy-consuming can overcome such troubles, support sustainable flow energy, achieve overall operational efficiency supply chain. However, establishing is complicated...

The economy of the Regional Integrated Energy System (RIES) scheduling scheme is affected by parameter accuracy different energy conversion equipment models. traditional static hub (EH) model regards efficiency as a constant and ignores variable condition characteristics changing with load rate. This paper presents an optimal method RIES considering under operating conditions. Firstly, architec...
