How to select a capacitor bank for power factor correction?
If 15% < N(LL ) < 25% you may want to consider a heavy duty PFC capacitor bank. If 25% < N(LL) < 50% our suggestion is a heavy duty PFC capacitor bank with suitable harmonic detuned reactors. If N(LL) ≥ 50% we recommend installing an active harmonic filter. This will allow you to calculate the percentage of non-linear loads in your network.

However, compensation components have to be chosen carefully. A compensation scheme can indeed improve stability, but can also lead the system to instability, depending on the choice of component values. Similarly, a compensation configuration can work for a specific load, but modifying this load can affect stability. Figure 11.
