This paper deals with the problem of optimal decentralized power control in systems whose spectrum is regulated in time and space, the so-called time-area-spectrum (TAS) licensed. This license system gives to the owner the right of using a given frequency band at a given time and within a given geographical area. In this paper we consider those locations with colliding transmissions; thus, addr...

This paper treats direct power control (DPC) for three-phase PWM rectifiers using a new switching table, without line voltage sensors and the fuzzy logic theory. The instantaneous active and reactive powers, directly controlled by selecting the optimum state of the converter, are used as the PWM control variables instead of the phase line currents being used. These strategies are used to elimin...

In this paper, direct power control (DPC) of three-phase PWM rectifiers based on fuzzy logic controller is presented, without line voltage sensors. The control technique is built upon the ideas of the well known direct torque control (DTC) for induction motors. The instantaneous active and reactive powers, directly controlled by selecting the optimum state of the converter, are used as the PWM ...

This article introduces a novel and effective diagram based on direct instantaneous power control (DPC) of PWM-controlled rectifier connected to the grid without switching table. An optimum vector PWM rectifier's input voltage, which depends states determined by Petri nets controller, is adopted. approach limits detection errors reactive active powers, maintains DC bus voltage at reference leve...

The control of a permanent magnet synchronous generator (PMSG) drive can be achieved through the implementation of different control techniques. This paper presents a comparative study of vector control and direct control techniques applied to PMSG drives for wind turbine applications. Rotor field oriented control (RFOC) and direct torque control (DTC) are considered for the generator-side conv...

This paper presents a novel direct power control (DPC) strategy based on an optimized sector division for three-phase coupled inductor-based bipolar output active rectifier (TCIBAR) applied in more electric aircraft (MEA). First, the instantaneous theory, model of TCIBAR is built synchronous rotating coordinate system. Second, to implement hysteresis without causing runaway zero-sequence curren...

This paper proposes a simple direct power control using space vector modulation (DPC-SVM) for three-phase threelevel neutral point clamped (3L-NPC) PWM converter connecting a wind turbine generator with grid. The active and reactive power are used as the control variables instead of the currents applied in conventional control method. Moreover, grid voltage sensors are replaced by a virtual flu...

Active Power Filter (APF) can significantly compensate the current harmonics produced by nonlinear loads. To do this feature, harmonic detection reference generation play vital role. Direct Controller (DPC) has great harmony with instantaneous power compensation (PQ) algorithm as well ability to eliminate internal loops. In addition, DeadBeat (DBC) high compatibility for digital implementation,...

Direct power control (DPC) is among the most popular schemes used in renewable energy because of its many advantages such as simplicity, ease execution, and speed response compared to other controls. However, this method characterized by defects problems that limit use, a large number ripples at levels torque active power, decrease quality result using hysteresis controller regulate capacities....
