Power Electronics is expected to become a major component in the field of the global electric power management, as it is already today within most of electric power applications like variable speed drives or other conventional user applications. From the e ...
This contribution presents control methods for the regulation of the voltage and the frequency on AC minigrids, fed by voltage source inverters (VSI). In order to avoid a complex communication network for the synchronization of the various VSI on a minigri ...
Variable speed pump-turbine units have become nowadays an interesting way to increase stability of electrical power networks due to their high level of operating flexibility. Different advantages offered by variable speed pump-turbine units for both pumpin ...
Advanced power flow control for multiple Flexible Alternative Current Transmission System (FACTS) devices is described here. An installation of multiple FACTS devices offers a great advantage concerning the flexibility of a system-wide power flow control. ...
In the technology sector of power electronics and control, the multilevel converter technology is still a rather new research area, but the application possibilities in the field of power drives and energy will demand more solutions with this promising tec ...
Problems in fault-tolerant distributed computing have been studied in a variety of models. These models are structured around two central ideas: 1. Degree of synchrony and failure model are two independent parameters that determine a particular type of sys ...
The present paper describes the modeling of Unified Power Flow Controllers (UPFC) for studying the steady-state and transient behavior of electrical networks equipped with FACTS devices. Detailed time-domain simulations are carried out on four model power ...
This work describes a development of a control system and control strategies capable of governing multiple flexible AC transmission system (FACTS) devices. The main purposes of the presented coordinated control system are to remove overloads and to achieve ...
Flexible AC Transmission Systems (FACTS) are systems based on power electronics using GTO or IGCT semiconductors [1] that allow a better use of the transfer capacities of the transmission lines and permit to satisfy the requirements due to the liberalizati ...
