controller design and optimization problems, with more than one objective, are referred as multiple objectives or multiple attributed problems. in this paper, a novel method is proposed for designing optimum pid controller that is called genetic multiple attributed decision making method (gmadm). this method is newer than the previous methods and in this paper some options are considered that h...

The work presented in this article is a contribution to the problem of controlling reactive powers and voltages an electrical network. Among these control tools, static power compensator (SVC) was chosen because its simplicity control. SVC one Alternative Flexible Current Transmission Systems (FACTS) devices which help solve problems encountered operation networks, either on distribution side o...

This paper presents a four-stage DC/DC converter with high precision and small ripple utilized in an electronic power conditioner (EPC). The galvanically isolated topology contains four cascade connections: buck circuit, push–pull converter, voltage regulator. switches, as well the diodes output-side rectifier, operate zero-voltage switching (ZVS) zero-current (ZCS) modes at both switch off on,...

Usage of flywheel energy storage system (FESS) is a common method for frequency regulation due to its high power injection capacity and long life time. FESS is equipped by two back-to-back inverters including grid-side inverter and machine-side inverter. In conventional method, the machine-side inverter sets the active power and machine flux while grid-side inverter sets the reactive power and ...

Wang Liang (Department of Control Science and Control Engineering, Huazhong University of Science and Technology, WuHan, 430074, P.R.China, E-mail: [email protected]) [Abstract] Climate modification measures to counteract global warming receive some more new attentions in these years. Most current researches only discuss the impact of these measures to climate, but how to design such a clima...
