Active power real-time control strategy for wind farm considering AGC adjustment capability Limits
2014 IEEE PES T&D Conference and Exposition, 2014Because of the intermittent and uncertainty of wind power, the change rate and amplitude of power system net-load increase with wind power penetration growing continuously. The prediction error of wind power generation capacity is large, so it's difficult to quantify its impact on AGC adjustment capacity and incorporate wind power maximally.

A Series Hybrid Active Power Filter with the function of Adjustable Fundamental Impedance
2020 23rd International Conference on Electrical Machines and Systems (ICEMS), 2020This paper proposed a series hybrid active power filter (SHAPF) with the function of adjustable impedance. The principle of SHAPF based on magnetic flux compensation is addressed. A linear transformer with air gap and multiple secondary windings is chosen, which are injecting specific currents into multiple secondary windings respectively.

Study on Fuzzy Controller with a Self-adjustable Factor of Active Power Filter
IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronics, 2006Active power filter has been proved to be a useful approach to eliminate current harmonics caused by nonlinear loads. This paper proposes a fuzzy controller with self-adjustable factor to control DC-link voltage of active power filter. The distinctive advantage of the fuzzy controller is that its fuzzy control rules can be modified according to the ...

Adjustable step-size LMS based IRP method for active power filter
2020 International Conference on Computer Communication and Informatics (ICCCI), 2020in this paper, an improved instantaneous reactive power (IRP) method has been proposed for computation of the reference current of the active power filter. The adjustable step-size least mean square (LMS) algorithm is integrated with the IRP method to improve its transient behaviour of the APF for compensating the harmonics currents.

A Low-Power Low-Phase-Noise VCO With Self-Adjusted Active Resistor
IEEE Microwave and Wireless Components Letters, 2016This letter presents a low-power low-phase-noise VCO with self-adjusted active resistor (SAAR). A pair of PMOS transistors is introduced between cross-coupled pairs and LC-tank, serving as the SAAR. When cross-coupled transistor resides in the saturation region, SAAR exhibits small resistance, enabling fast switching and suppressing flicker noise up ...

Active Adjustable Coil Receiver for Adaptive Output Power Based on Wireless Power Transfer
International Journal of Circuit Theory and ApplicationsABSTRACT The wireless power transfer (WPT) system operates under variable load conditions. During different stages of charging, the power required by the load varies. Therefore, the WPT needs to adjust the voltage and power in real‐time to meet these differing demands.

Reconfigurable active front-end of adjustable speed drives for power quality improvement
2009 IEEE Power & Energy Society General Meeting, 2009A new control scheme is proposed to utilize the active front-end of a high performance adjustable speed drives (ASD) to solve power quality problems caused by conventional diode/thyristor drives. Under the proposed control scheme, a fully controlled active front-end ASD acts as a local power quality conditioner in order to compensate harmonic currents ...

Active power control for preventing voltage instability using an adjustable speed machine
2001 Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.01CH37262), 2001One cause of power system voltage instability is the loss of short-term operation equilibrium after a disturbance. This paper proposes an active power control method for preventing short-term voltage instability. The active power control is implemented by means of an adjustable speed machine, which is primarily used as a synchronous condenser, but ...

IEEE Transactions on Antennas and Propagation, 2019
In this article, we propose a polarization adjustable active receiving antenna that covers the full 60 GHz ISM band (57–66 GHz) to improve the signal-to-noise ratio (SNR) degenerated by polarization mismatch with the transmitter. The proposed antenna not only controls the receiving angle of linear polarization (LP) but also controls the axial ratio of ...
