In order to minimize power losses caused by high current and improve the voltage profile in the network distribution, the introduction of dispersed generations also called productions decentralized in distribution network (DG) plays an important role. The installation of DGs directly affects the power requested or purchased. The sizing and placement of DGs in the system must be optimal because ...

In this article, we propose an optimal decentralized robust $H_\infty $ control system for the voltage problem of autonomous uncertain dc microgrids consisting multiple distributed generations (DGs) with general topology. The one-degr...

Nowadays, the penetration of distributed generations (DGs) and microgrids (MGs) has been significantly increased due to technical, social, environmental, financial reasons. One most common types DGs which is widely used in different networks small-scale synchronous generators (SSSGs). Synchronous-based (SGBMGs) SSSGs can operate under both grid-connected islanded conditions. To guarantee a stab...

A distributed control strategy is developed to control the output of multiple distributed generators (DGs) in a coordinated fashion such that these generators develop into a virtual power plant (VPP) in a distribution network. To this end, cooperative control methodology from network control theory is used to make the VPP converge and operate at an optimal output, which is determined by the DGs...

A distributed hypermedia storage service--called the UNC Distributed Graph Service (DGS)--will become the database for a hypermedia computer-supported, cooperative work environment called ABC. The DGS data model has been designed to support the unique storage needs of users who are collaborating to solve complex problems. Since it is based on the formalism of directed graphs, the DGS data model...

This paper presents three stages of methodology. The first stage is to identify the switching operation for radial network configuration while observe the power losses and the voltage profile without Distributed Generation (DG). The second stage is based on previous paper which is feeder reconfiguration for loss reduction with DGs. The last stage is sizing and allocation DGs at buses with low v...

Distribution System State Estimation (DSSE) techniques have been introduced to monitor and control Active Networks (ADNs). DSSE calculations are commonly performed using both conventional measurements pseudo-measurements. Conventional typically asynchronous low update rates, thus leading inaccurate results for dynamically changing ADNs. Because of this, smart measurement devices, which synchron...
