This paper proposes a dynamic capacitor (D-CAP) based on the family of inverter-less active filters that is able to provide a dynamically controllable capacitance with active harmonic filtering integrated into the same unit. This new device is seen to be compact, and is likely to be cost competitive against simple switched shunt capacitors.
To mitigate these adverse effects, active filters are employed. The objective of this study is to investigate a synergistic approach to modeling and control in integrated power systems with GFMs, focusing on enhancing power quality and grid stability by reducing harmonic distortions through the use of voltage-source active filters.
Thus, the figure visually supports the description of the system’s response to sudden load changes, grid disconnection, and the involvement of multiple non-linear loads while highlighting the role of the shunt active filter in mitigating harmonic distortion.
The inductance of the filter is one such parameter with clear boundaries. On the lower end, if the inductance is too low, the filter may fail to sufficiently attenuate harmonic currents, leading to poor harmonic compensation and a higher ripple in the system’s current, which can stress the inverter’s switching components.
The inverter’s primary responsibility is to maintain the grid’s voltage and frequency, while the active filter focuses on improving power quality by mitigating harmonics and stabilizing the DC link voltage [15, 16]. Figure 1. Integrated power system network . 2. Integrated System Control
Figure 2. Droop control of grid-forming inverter [3, 16]. The main purpose of the active power droop control loop is to adjust the inverter’s output frequency by regulating the active power output. The control loop uses a droop characteristic, which is a linear relationship between the frequency deviation and the active power output.
