Traditionally, Electrical power plant capacities are determined after specific plant locations have been selected. In this paper an expansion policy of power plant centers involving the choice of regions that must be allocated to power plant centers and power plant centers capacities over a specified planning horizon (years) is tackled. The problem is performed as a mixed integerprogramming mod...

In this paper an overview of functionally graded materials and constitutive relations of electro elasticity for three-dimensional deformable  solids is presented, and  governing equations of the Bernoulli–Euler and Timoshenko beam theories which account for through-thickness power-law variation of a two-constituent material and piezoelectric layers are developed  using the  principle  of virtua...

Interactive museum exhibits have increasingly placed replicated and virtual objects alongside exhibited authentic objects. Yet little is known about how these three categories of objects impact learning. This study of family learning in a botanical garden specifically focuses on how 12 parent-child family units used explanations as they engaged with three plant types: living, modeled, and virtu...

In the upcoming years, an opportunity for a wide range of electricity management solutions arises, thus several researchers have focused their efforts on studying and analyzing various subjects related to the operation of microgrids, smart grids, Vehicle-to-Grid (V2G), responsive demand, among others. On the other side, especially at engineering courses, these topics are primarily covered from ...

The increasing penetration of renewable energy sources and electric vehicles (EVs) poses a significant challenge for the power grid operator in terms peak load quality reduction. Moreover, there is growing demand fast charging services smart grids. Addressing from challenging. To overcome this challenge, article, we propose new computational architecture combining trading responses based on clo...

A virtual power plant (VPP) is a cloud based distributed that aggregates the capacities of diverse energy resources (DERs) for purpose enhancing generation as well trading or selling on electricity market. The main issue faced while working VPPs management. Smart management VPP complex problem due to coordinated operation and their associated uncertainties. This research paper proposes real-tim...

the aim of this study is to find the optimal water pressure and percentage of supply vapour in the feed water heaters (fwhs) of steam power plants, such that they maximize the thermal efficiency of the rankine cycle within pre-specified values of minimum and maximum pressures of the thermodynamic cycle. thermal efficiency is defined as a function of unknown variables (fluid pressure and vapour ...
