The increasing penetration of load model in distribution systems may significantly affect voltage stability of the systems, particularly during Low Voltage Ride-Through (LVRT) wind turbine. The main objective of this work is to present the impact of different static and dynamic load models, on the LVRT recovery after disturbances. A component and composite loading structures are considered, com...

This article discusses the nonlinear behavior of corrugated packaging during compression. The model this is a load-displacement curve with an ascending branch, peak point and descending branch. In some cases, branch shows signs plastic transition and/or loss stability container walls. purpose work to predict into (or pseudo-plastic) state. condition unacceptable because there are residual defor...

1.1. Problem definition: Neuro-Fuzzy Approach in Electrical Load Forecasting Modeling and identification of electrical load processes are essential for the operation and also planning of a utility either for a company or for a country. Electrical load forecasting is needed because people intend to make important decision on generating power generators, load switching, purchasing strategy and al...

conventional passive distribution networks are changing to modern active distribution networks which are not radial. conventional load flow methods should be modified for new distribution networks analysis. in modern distribution networks distributed generation (dg) units are embedded with conventional and/or renewable resources. dg units are generally modeled as pv or pq nodes which inject ...

thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. to implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were der...

Efficient load models are essential and important for power system load modeling constraint voltage stability studies. Dynamic load models allow a more precise calculation of stability limits that are critical in the planning and operation of power systems. Voltage stability which defines ability of a power network to maintain steady voltages deals with many a kind of disturbance parameters. Va...

This paper deals with the modeling of punching shear failure in reinforced concrete slabs using nonlinear finite element analysis. The 3D finite element analyses (FEA) were performed with the appropriate modeling of element size and mesh, and the constitutive modeling of concrete. The FE numerical models are validated by comparing with the experimental results obtained from tested specimens and...
