In most highly developed electrical power system, there are several difficulties related from generation to distribution. Usually, power generation is located at remote area from the load center. Long transmission and distribution lines have to be constructed and maintained to meet required reliability, power quality and economic point of views. Reliable, cheap, efficient conductor is required ...

• Deposit particles on the (Nx, Nz) grid. • Apply 2D FCT on the grid, thus yielding (Nx, Nz) cosine coefficients. • The high-frequency contribution to the density is then removed by filtering (truncating) coefficients higher than Ncx and Ncz: – this removal of the high-frequency components results in a smoother distribution, but it also removes small scale structures that may not be due to nois...

Distribution grids evolve more and more to so called “Smart Grids” with a decentralized structure. New information and communication technologies (ICT) to manage these “Smart Grids” are necessary to integrate a high share of renewable energy systems. Due to a high number of system components the optimal operation and control of “Smart Grids” is highly complex which is why this paper uses the ap...

Finding interesting symmetrical topological structures in high-dimensional systems is an important problem in statistical machine learning. Limited amount of available high-dimensional data and its sensitivity to noise pose computational challenges to find symmetry. Our paper presents a new method to find local symmetries in a low-dimensional 2-D grid structure which is embedded in high-dimensi...

A study, based on product related scenarios, on power supply integrity issues is conducted. The effectiveness of specific design parameters depends strongly on the expected loading of the power distribution grid. Therefore, the commonly used approach to only use an even current distribution can lead to non-optimal power grid designs. For power grid optimization, a problem reduction from quadrat...

One of the expectations from a smart grid is that it will be more efficient and reliable than a traditional power grid. The electric power distribution system is expected to change drastically. With the involvement of modern high-speed communication and computational applications, the speed with which one can monitor actions on a grid has increased. The incorporation of distributed renewable en...

We suggest a novel method of clustering and exploratory analysis of temporal event sequences data (also known as categorical time series) based on three-dimensional data grid models. A data set of temporal event sequences can be represented as a data set of three-dimensional points, each point is defined by three variables: a sequence identifier, a time value and an event value. Instantiating d...

State estimation is used in power systems to estimate grid variables based on meter measurements. Unfortunately, power grids are vulnerable to cyber-attacks. Reducing cyber-attacks against state estimation is necessary to ensure power system safe and reliable operation. False data injection (FDI) is a type of cyber-attack that tampers with measurements. This paper proposes network reconfigurati...

Iran is a country completely dependent on fossil fuel resources. In order to obtain a diversity of energy sources, it requires other resources, especially renewable energy. Utilization of wind energy appears to be one of the most efficient ways of achieving sustainable development. The quantification of wind potential is a pivotal and essential initial step while developing strategies for the de...
