In the article the role of legacy systems in the next generation distributed object architecture is discussed. Legacy systems represent an enormous investment in time and money and they embody a wealth of intellectual property, business rules and data. Replacing them with new generation systems is not possible over night. The way how to integrate these systems within distributed object architec...

This paper explores the structure, use, and value of Distributed Grid Management as a process and technology to support distributed grid optimization functions and microgrids to better integrate into the electrical grid small quantities of local, distributed power generated from renewable resources. The paper describes the value of distributed distribution management as it applies to Microgrids...

This article presents a Radial Basis Neural Network (RBNN) based islanding detection technique. Islanding detection and prevention is a mandatory requirement for grid-connected distributed generation (DG) systems. Several methods based on passive and active detection scheme have been proposed. While passive schemes have a large non detection zone (NDZ), concern has been raised on active method ...

This paper presents an energy management strategy to supply residential load by hybrid fuel cell power plant (FCPP). Economical fuel cell (FC) model includes thermal load, local electrical load, operational cost, startup cost and different tariffs on electricity during the day hour is discussed.  Several Strategies have been presented for supplying residential load (electrical and thermal loads...

in this paper, the impacts of installing superconducting fault current limiter (sfcl)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (dg). among various sfcls, the hybrid type with a superconducting element in parallel with a current limiting reactor (clr) is selected. this is more effective than resisto...

distributed generations (dgs) are utilized to supply the active and reactive power in the transmission and distribution systems. these types of power sources have many benefits such as power quality enhancement, voltage deviation reduction, power loss reduction, load shedding reduction, reliability improvement, etc. in order to reach the above benefits, the optimal placement and sizing of dg is...

In general, a large percentage of the electric power produced is generated in huge generation centres far from the consumption, and with centralized transmission and distribution systems, where the weak point of this scheme is the efficiency with high energy losses in the form of heat. This problem has been increased in the last years due to the significant growth of electric energy demand and ...
