Generalized Direct Power Control for multilevel VSR converters

Eurocon 2013, 2013
A fast and effective control of three-phase PWM-Rectifiers is presented in the paper, with reference to multilevel converter topologies. The presented strategy con be considered a “Direct Power Control” (DPC) because it is devoted to the direct control of active and reactive line-power, using a technique very similar to the well-known “Direct torque ...

Direct power control of PWM converter without power source voltage sensors

IAS '96. Conference Record of the 1996 IEEE Industry Applications Conference Thirty-First IAS Annual Meeting, 1998
This paper proposes a novel control strategy of a pulsewidth modulation (PWM) converter with no power-source voltage sensors. The strategy has two main features to improve a total power factor and efficiency, taking harmonic components into account without detecting the voltage waveforms.

Comparative analysis of direct power control and direct power control with space vector modulation of PWM rectifier

2016 4th International Conference on Control Engineering & Information Technology (CEIT), 2016
This paper presents a comparative analysis of direct power control (DPC) and direct power control with space vector modulation (DPC-SVM) of three phase PWM rectifier. In the first strategy has been developed to control the instantaneous active and reactive power directly by selecting the optimum switching state of the PWM rectifier.

Direct Power Control of Dfig by Using Nonlinear Model Predictive Controller

Asian Journal of Control, 2015
AbstractThis paper proposes a nonlinear model predictive direct power control (PDPC) strategy for a double fed induction generator (DFIG)‐based wind energy generation system. Active and reactive power variations of DFIG are calculated based on machine rules, and a nonlinear model of DFIG is given.

Fractional direct power control for active filter

2013 IEEE 7th International Power Engineering and Optimization Conference (PEOCO), 2013
Fractional order direct power control (FO-DPC) has been proposed in this paper, this command applied to active power filters (APFs) with fractional PI regulator to control DC-bus voltage of the capacitor, this active configuration of APF allows us to control the active and reactive power and compensate the harmonics of current.

Hybrid Renewable Energy System Controlled with Intelligent Direct Power Control

Journal Européen des Systèmes Automatisés, 2022
The paper suggests a novel DPC approach to ameliorate the management and HRES “hybrid renewable energy system” control composed of photovoltaic and wind systems. In the conventional DPC technique, the “switching table” is founded on a “hysteresis comparator”, which poses the problem of fluctuations on the HRES various output variables.

Direct Power Control of Induction Motor Drives

2019 IEEE 13th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2019
In this paper a novel high-performance direct power control (DPC) approach for induction motor (IM) drive is presented. The majority of the high performance drives employ induction machine due to its several advantages and hence it necessitates precise control over a wide range of speed with better power factor.
