Rotor Position-Sensorless Algorithms for Direct Power Control of Rotor-Tied DFIG
IEEE transactions on power electronics, 2021In this letter, direct power control (DPC) of rotor-tied doubly fed induction generator (DFIG) is presented for the first time. First, a theoretical study is presented to acknowledge the fundamentals of DPC of rotor-tied DFIG.

Parallel model predictive direct power control of DFIG for wind energy conversion
, 2021This paper presents a parallel model predictive power control (PMPPC) method of doubly-fed induction generator (DFIG) for variable-speed wind turbine applications (VSWT). The use of a hysteresis controller and a predefined switching table will inevitably

Direct Power Control of Three-Phase Electric Springs
IEEE transactions on industrial electronics (1982. Print), 2021Three-phase electric spring (TPES) was originally proposed to solve three-phase imbalance issues in power systems. So far, several attempts have been reported on proposing power control methods for it. However, existing solutions on TPES either depend on

Light-powered direction-controlled micropump
Nano Research, 2018A micropump induces the flow of its surrounding fluids and is extremely promising in a variety of applications such as chemical sensing or mass transportation. However, it is still challenging to manipulate its pumping direction. In this study, we examine a binary micropump based on perovskite and poly[(2-methoxy-5-ethylhexyloxy)-1,4-phenylenevinylene]

Direct power control for Universal Power Flow Controller series converter
2010 IEEE Energy Conversion Congress and Exposition, 2010To maximize the power flow in a transmission grid while maintaining stability, unnatural power flows can be enforced by a Unified Power Flow Controller. Theoretically the control of active and reactive power flow can be without overshoot or cross coupling.

Direct power control of shunt active filter
2007 European Conference on Power Electronics and Applications, 2007This paper presents a new control method entitled direct power control (DPC) for shunt active power filtering, which is applied to eliminate line current harmonics and compensate reactive power. Its main goal is to rebuild active and reactive powers to be compared to references values using hysteresis control.

Direct Control of Power System Dynamics
2021One of the main causes of power system instability is low-damped inter-area oscillations. It is important to damp out low-frequency oscillations effectively and to provide necessary precautions in order to avoid major separations of power systems and cascading blackouts.

Direct power control for distributed PV power system
Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003A novel approach to the DSP-based control of photovoltaic (PV) energy storage systems for distributed PV module is presented. A DSP is used to implement the power feedback control, maximum power point tracking (MPPT) and unfalsified control for the PV system. A MPPT control with duty ratio versus PV module output power has been developed.

A novel predictive direct power control
11th International Conference on Electrical Power Quality and Utilisation, 2011In this paper a recently introduced predictive direct power control (P-DPC) method for three-phase power rectifiers is improved by using a more accurate mathematical model. In general P-DPC is a parameter dependent approach and inaccuracies in mathematical model, wrong estimation of the inductor or even filtering the feedback signals may result in ...
