The paper describes three aspects of virtual market of electrical energy. Legislative base of alternative source using in energy-supply system including "green tariff" is presented. Calculation of economical parameters in order to estimate effectiveness of different alternative source is made. Technical solution for DC, AC, and hybrid energy transmission schemes are developed.
The Unified Power Flow Controller is the most advanced device of FACTS family. It is able to control active and reactive power and voltage magnitude simultaneously. A control range of these system parameters is dependent on UPFC's inverter constraints and also on operating conditions of the power system. In this paper, the results of investigations of influence of UPFC constraints and operating conditions...
This paper presents the application of an adaptive neuro-fuzzy controller (ANFC) for speed control of the switched reluctance generator (SRG). In this study, the SRG is driven by a variable-speed wind turbine and connected to the grid through an asymmetric half bridge inverter, DC-link, and DC-AC inverter system. Speed control plays an important role in variable-speed operation of the SRG to ensure...
