d-ACTM/VT: A Distributed Virtual AC Tree Detection Method

Islanding Detection Method of Distributed Generation Based on Wavenet

Due to the increasing need to distributed energy resources in power systems, their problems should be studied. One of the main problem of distributed energy resources is unplanned islanding. The unplanned islanding has some dangers to the power systems and the repairman which are works with the incorrect devices. In this paper, a passive local method is proposed. The proposed method is based on...

Monotone AC-Tree Automata

We consider several questions about monotone AC-tree automata, a class of equational tree automata [21] whose transition rules correspond to rules in Kuroda normal form of context-sensitive grammars. Whereas it is known that this class has a decision procedure to determine if a given monotone AC-tree automaton accepts no term [23], other decidability and complexity results have not been well-in...

A Distributed Control Architecture for Autonomous Operation of a Hybrid AC/DC Microgrid System

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

Distributed Spatial Data Warehouse Indexed with Virtual Memory Aggregation Tree

In this paper we present a distributed spatial data warehouse system designed for storing and analyzing a wide range of spatial data. The data is generated by media meters working in a radio based measurement system. The distributed system is based on a new model called the cascaded star model. In order to provide satisfactory interactivity for our system, we used distributed computing supporte...
