“…2. For this purpose, a PI-based selective harmonic compensation (SHC) technique [29] is used in the Note that the DC-link voltage control scheme and the type of modulation depend on the VSC topology used, whereas the frequency control scheme can be used with any VSC topology. Moreover, the conventional voltage oriented control using PLL, that is needed for the synchronization of the VSC output voltage with the controller reference frame, becomes unfeasible due to the missing AC-voltage source [12].…”

“…This can be achieved through a controlled reactive power generated by a VSC placed at the DR station. The VSC power demand for the frequency control depends on the system and control parameters and the transients in the system, as analyzed in [29]. However, this centralized solution is derived from an average-value model (AVM) of the DR system where a high voltage large capacitor bank is also needed to be placed at the DR station.…”

“…Using the same control strategy, [29] presents an APF scheme embedded in the frequency control, which is implemented by a VSC placed at the DR station, thereby removing the DR passive AC-filters. However, a capacitor bank is still needed to be placed at the DR station for the frequency control.…”

“…The properties of this combination are well-known: the BTB-VSC is used to supply an unitary power factor at each AC side; the DC bus voltage is generally higher than the peak AC source voltage standard [28]. In fact, this type of configuration is the most used for WECS and MAECS [6,12,[18][19][20][21][22]. To achieve the objectives described above, control of the BTB-VSC is developed considering synchronous coordinates such as the rotating (dq0) [6,7,12,14,15,18,22,25,27,31] and stationary (αβ0) [17,23,29,31], as well as the time-domain or conventional (abc) [9,26,30], reference frame.…”

The Performance of the BTB-VSC for Active Power Balancing, Reactive Power Compensation and Current Harmonic Filtering in the Interconnected Systems

Nowadays, the use of power converters to control active and reactive power in AC–AC grid-connected systems has increased. With respect to indirect AC–AC converters, the tendency is to enable the back-to-back (BTB) voltage source converter (VSC) as an active power filter (APF) to compensate current harmonics. Most of the reported works use the BTB-VSC as an auxiliary topology that, combined with other topologies, is capable of active power regulation, reactive power compensation and current harmonic filtering. With the analysis presented in this work, the framework of the dynamics associated with the control loops is established and it is demonstrated that BTB-VSC can perform the three tasks for which, in the reviewed literature, at least two different topologies are reported. The proposed analysis works to support the performance criteria of the BTB-VSC when it executes the three control actions simultaneously and the total current harmonic distortion is reduced from 27.21% to 6.16% with the selected control strategy.

“…Besides that, P. Mattavelli et al at [19] have proposed a repetitivebased controller to compensate the selected harmonic current. As the phase angle of harmonic will affect the results of the harmonic compensation, a selective harmonic compensation method based on the dynamic phasor theory is proposed in active power filtering [20]. And an active compensation method through the jittering of selective harmonic elimination phase angle is applied to high-power PWM converters' system [21].…”

Multiple Harmonic Current Injection System for Audible Noise Analysis of AC Filter Capacitors in Converter Stations

et al. 2020

The audible noise of AC filter capacitors is one of the major noise sources in High Voltage Direct Current (HVDC) converter stations. In order to avoid the sharp noise of AC filter capacitors, it is necessary to design a Multiple Harmonic Current Injection System (MHCIS) for power capacitors to analyze their audible noise characteristics. Simulating effectively the noise of AC filter capacitors under their actual working conditions in converter stations is the primary target of this proposed MHCIS. To ensure the accuracy of the harmonic currents injected into the power capacitors, each harmonic current is detected and controlled separately. On the basis of the instantaneous reactive power theory, a selective harmonic current detection algorithm is proposed in this paper for the single-phase MHCIS. The amplitude of the selected harmonic current can be tracked timely and exactly in d-q synchronous rotational coordinate system, such that a Proportional Integral (PI) controller can be directly operated to eliminate the steady-state errors. The experimental parameters are usually invariable in this system, the phase deviation of the selected harmonic current is also fixed. Thus the phase angle offset of the corresponding harmonic current can be detected and calculated to compensate the system inherent delay. Owing to the accurate detection and control of multiple harmonic currents, the actual working conditions of AC filter capacitors can be accurately simulated, and the reliable noise analysis results of power capacitors can be obtained. Finally, the proposed selective harmonic current detection and control algorithm is verified by the theoretical analysis, simulation and experimental results.
