This paper provides an efficient control technique for the operation of a direct-drive synchronous generatorbased stand-alone variable-speed wind energy conversion system. The control strategy for the generator-side converter with maximum power extraction is presented. This control provides a constant output voltage and frequency which capable of delivering to variable loads. The main attention...

this paper presents a cooperative control which is applied to the secondary control of a microgrid controlled via a multi-agent scheme. balancing power that leads to voltage and frequency stability in a microgrid is essential. the voltage and frequency regulations are limiting within the specified limits and conveying them to their nominal values. limiting and conveying the voltage and frequenc...

This paper discusses the design and simulation of Slope compensated Current mode Controlled Boost converter which is used in several applications like regulated switch mode dc-dc power supplies. There are several types of dc-dc converters. A boost converter simply steps up a source voltage to a higher, regulated voltage. This allows one power supply to provide different voltage levels at differ...

Boost half bridge DC-DC converters in the combination of an input-series and output-series (ISOS) connected configuration with a stable control strategy has been investigated in this paper. A stable control strategy comprises of two loops that are current loop and voltage loop. The reference to the current loop has been chosen from the input side of the DC-DC converter. The reference to the vol...

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...

This paper concentrates on the control of hybrid fuel cell/energy storage distributed generation systems under voltage sag in distribution systems. The proposed control strategy makes hybrid distributed generation system works properly when a voltage disturbance occurs in distribution system and it stays connected to the main grid. To distribute the power between dc power sources and stabilize ...

this paper describes how multi-agent system technology can be used as the underpinning platform for voltage control in power systems. in this study, some facts (flexible ac transmission systems) devices are properly designed to coordinate their decisions and actions in order to provide a coordinated secondary voltage control mechanism based on multi-agent theory. each device here is modeled as ...

An input-series output-parallel (ISOP) system, in which multiple converter modules are connected in series at the input sides and parallel at the output side, is very suitable for high input-voltage, low output-voltage, and high output-current applications. Input-voltage sharing (IVS) and output-current sharing of the constituent modules among the ISOP system must be ensured. The existing IVS c...

Abstract: Active Power Filter (APF) is capable of changing the size and frequency of harmonics as well as changes in reactive power compensation. It is important to control the stability of the DC-link capacitor voltage stability for it. For DC voltage controls of APF, there are two important achievements. First, it is indicated that the control of DC voltage directly affects the compensation p...
