microgrids are small-scale, low voltage (lv) power networks which employ renewable distribution energy resources (ders) with power electronic interfaces (peis). microgrids as single controlled units and active distribution networks require flexible control systems to ensure reliable and secure operation in different modes. these various operations of microgrid cause variations in voltage and fr...

Dynamic and adaptable integration of Distributed Energy Resources (DERs) into novel power system assets, such as microgrids, is one of the key prerequisites for accelerated Smart Grid deployment. By using standardized network interfaces and semantic descriptions for remotely controllable DERs, it is possible to develop intelligent microgrid applications capable of dealing with dynamic loads and...

Control systems for electrical microgrids rely ever more on heterogeneous off-the-shelf technology for hardware, software and networking among the intelligent electronic devices that are associated with dispersed energy resources. For distributed microgrid applications in a dynamic environment, overlay networks provide an opportunity for a flexible and robust logical communication infrastructur...

In a recent paper, we constructed a basis for the contact-order filtration of the module of derivations on the orbit space of a finite real reflection group acting on an -dimensional Euclidean space. Recently M. Yoshinaga constructed another basis for the contact-order filtration. In this note we give an explicit formula relating Yoshinaga’s basis to the basis we constructed earlier. The two ba...

Distributed energy resources DER constitute a relatively new paradigm in the electric power industry. The concept is gaining popularity because of the inherent modularity of DERs. They can be regarded as more flexible power sources, albeit with limited capacity, than centralized power units. DERs are power generation or storage units that are connected directly to the distribution network or co...

emotion regulation difficulties are from the factors that caused the incidents and automobile accidents and work related. this study aimed to comparing emotion regulation difficulties in mild traumatic brain injury (tbi) patients and normal people in kashan.the study was performed on 30 tbi patients referred to shahid beheshti hospital in kashan city and 30 normal people in kashan. tbi patients...

This paper presents an online two-stage Q-learning based multi-agent (MA) controller for load frequency control (LFC) in an interconnected multi-area multi-source power system integrated with distributed energy resources (DERs). The proposed control strategy consists of two stages. The first stage is employed a PID controller which its parameters are designed using sine cosine optimization (SCO...

Cytogenetic evaluation is an important step in the diagnosis of infertile or sterile animals. Moreover, the analysis of sex chromosomes is crucial for a proper classification of disor‐ ders of sex development (DSD). For many years, chromosome studies mainly addressed the livestock species, while recently, increasing interest in such analysis in companion an‐ imals is observed. New molecular and...

We present a general approach to speeding up afamily of multi-relational data mining algorithmsthat construct and use selection graphs to obtain theinformation needed for building predictive mod-els (e.g., decision tree classifiers) from relationaldatabase. Preliminary results of our experimentssuggest that the proposed method can yield 1-2 or-ders of magnitude reduc...
