Direct Power Flow Controller—A New Concept in Power Transmission

IEEE Transactions on Power Electronics, 2020
For power transmission in grid, a new concept of direct power flow controller (DPFC) was proposed based on single-stage ac–ac converter with controllable phase and amplitude. By connecting its regulated output compensation voltage with grid in series, DPFC is able to regulate the amplitude and phase angle of grid node voltage, and thus can effectively ...

Enhanced predictive direct power control of DFIG

2011 2nd Power Electronics, Drive Systems and Technologies Conference, 2011
This paper proposes an enhanced predictive controller for direct power control of doubly fed induction generator (DFIG). In this paper, a control law based-on the transfer function model is described to compensate and regulate the differences between the output active and reactive power of stator of DFIG that is in interaction with the network.

Sensorless Direct Power Control for a DSTATCOM

Proceedings of the 41st International Universities Power Engineering Conference, 2006
A Static Compensator (STATCOM) is a viable solution for improving power quality in distribution systems. This technology has resulted in an equipment that is principally different from conventional static Var compensator (SVC). In this paper Direct Power Control of three-phase pulsewidth-modulated inverter without voltage line sensors is applied to a ...

Design of STATCOM Novel Direct Power Controller

2011 Third International Conference on Measuring Technology and Mechatronics Automation, 2011
The main function of STATCOM is to compensate reactive power on-line, making the power system have ideal power factor. According to the instantaneous power theory, a novel control method is proposed in this paper that power is detected to be the reference compensation power direct.

Direct power control of DFIG connected to unbalanced power grid

2013 Eighth International Conference and Exhibition on Ecological Vehicles and Renewable Energies (EVER), 2013
This paper presents a control strategy, which allows doubly-fed induction generator (DFIG) to generate a sinusoidal stator currents and minimize an electromagnetic torque oscillations under unbalanced grid conditions. The control does not require a positive and negative sequence decomposition of the control variables, so the independent control of ...

Implementation of Direct Power Control for shunt active power filter

3rd International Conference on Systems and Control, 2013
This paper deals with implementation of Direct Power Control (DPC) using conventional PI controller applied to shunt active filters (SAPFs) using new parameters. The PI controller regulates the DC-link voltage, active and reactive power-flows of the power filter.

Direct load control for wind power integration

2011 IEEE Power and Energy Society General Meeting, 2011
Output power fluctuation of high penetration of wind power causes demand and supply imbalance in electric power systems and results in frequency deviation if the fluctuation is not fully compensated by other regulable power plants. In Japan, some electric utilities have started to accept only the wind farms which disconnect and give up generating power

Direct powers control of DFIG through direct converter and sliding mode control for WECS

2015 3rd International Conference on Control, Engineering & Information Technology (CEIT), 2015
In this paper, a sliding mode control technique is applied to control a variable speed wind energy conversion system (WECS) with a doubly fed induction generator (DFIG) and a cycloconverter. The dynamic behavior of the WECS, including the models of the wind turbine, the DFIG, the cycloconverter and the powers control, is investigated.

Power-Controlled Directional Medium Access Control for Wireless Mesh Networks

2006
Wireless Mesh Networks have emerged recently as a technology for next-generation wireless networking. To increase the performance of wireless nodes in such networks many approaches have been proposed, including directional and adaptive antennas. However, while adaptive antennas can improve the utilization of the wireless medium by reducing radio ...
