Efficient generation of scenarios is a central problem in evaluating the expected value of a random function in the stochastic optimization. We study the use of sparse grid scenario generation method for this purpose. We show that this method is uniformly convergent, hence, also epi-convergent. We numerically compare the performance of the sparse grid method with several Quasi Monte Carlo (QMC)...

The term "smart grid" generally refers to a next-generation power grid in which the generation, transmission, distribution, and management of electricity are upgraded and automated by incorporating advanced computing and communication technologies for improving the efficiency, reliability, economics, and safety of the grid. Loosely speaking, a smart grid is composed of a power grid and a two-wa...

Homes, buildings and industrial facilities together represent nearly 100 % of the load on the electric grid. Beyond load, these facilities comprise a significant amount of electricity generation and thermal storage. These customer-owned load, storage and generation resources must be made responsive to needs of the electric grid in order to enable the Smart Grid. At issue is the best way to acco...

To meet the growing demand for clean energy and improved availability factor in South Africa, various solutions are being proposed from academia industry. Therefore, this study, a non-conventional method of generating was designed constructed. The system harnesses kinetic vehicles driving over speed bumps converts it to electrical using generator. This is supplemented with generated solar PV pa...

As a new branch of grid computing, e-Learning grid is emerging as a nationwide e-Learning infrastructure, which can provide innovative learning experience for learners. In such a grid environment, collaboration services will be the key elements due to the pervasive requirement for cooperative work and collaborative learning. Although there exist enormous research efforts on grid-based collabora...

This chapter describes the general principles of unstructured mesh generation in two and three dimensions, together with the use of finite elements in modelling space plasmas. Particular attention is given to the requirement of generating meshes that are aligned along magnetic field lines, in order to properly capture the strong anisotropy of magnetised plasmas. Example results are given in 2D ...

The growing rate of energy consumption is a reason for establishment of new power plants which leads to increment in fault current level. One of the solutions to overcome this problem is utilization of fault current limiters (FCLs). Another concerning issue in energy generation is the satisfactory voltage quality in grid and to deal with it, a power electronic based device, known as dynamics vo...
