As we can see from Equations (4) and (5) reduction of reactive power transported from generating station to the customers will lead to reduction of both active power losses and voltage drops. To achieve this goal, local sources of reactive power may be used: either shunt capacitors for inductive load, or shunt reactors for capacitive load. Let ...
if you put parallel both L and N will surpresed against high amperage reactance power from the load. capacitor in AC parallel for PFC working like dampening the load. yes it's charging and giving output in the next cycle so your reactance power decreasing.
With the capacitor in parallel, there is now an additional source of energy, which can take up some/all of the burden of supplying current to the inductive load (when it resists changes in current till it sets up its field), after which the source takes over again and recharges the capacitor.
By finding "the magnitude of the power supply voltage", "the magnitude of the current flowing in the RLC parallel circuit", and "the power factor of the RLC parallel circuit," the active power , reactive power , and apparent power can be calculated. The apparent power can be obtained by the following equation.
The power factor of an RLC parallel circuit is the ratio of the impedance magnitude to the resistance and can be obtained by the following equation
So, to correct the power factor, an ideal parallel capacitor will simply make for a new total impedance of ∣∣∣ ZCZL ZC +ZL ∣∣∣ = |ZL|2 RL> |ZL| | Z C Z L Z C + Z L | = | Z L | 2> | | which means we'll draw less apparent power than before -- thus, satisfying the objectives of power factor correction!

In contrast, parallel connection of an appropriately sized capacitor keeps the reactive current local, constrained to short low-loss wiring runs.
To compensate for the voltage drop over the reactance, different methods can be used. If an active rectifier is used it could provide reactive power to compensate for the voltage drop. Another method is to use capacitors connected to the generator either in parallel or in series with the generator coils.
When the reactive power provided by the AC filter is not enough to meet the capacitive reactive power requirements of the converter, the remaining capacitive reactive power requirements are supplemented by the parallel capacitor device. 1 Harmonic components of the converter station 1.1 Overview
The traditional means of correcting power factor for the typical lagging circuit is by installing capacitance to generate some of the reactive power required by the load so as to remove the necessity of the supply from providing it.
Reactive power demand varies throughout the day. During the lightly loaded conditions, there will be excess reactive power i.e. capacitive reactive power available and it is necessary to connect parallel reactors for consuming the additional capacitive reactive power of the lines or else to change the on- load transformer tap change settings.

In contrast, parallel connection of an appropriately sized capacitor keeps the reactive current local, constrained to short low-loss wiring runs.
When connected in parallel, the capacitor acts as a reactive element that helps balance out the reactive power of the inductor, thus improving the overall power factor. On the other hand, if a capacitor is added in series with the load, it would act as a resistive element and reduce the overall impedance of the circuit.

Since capacitors have a leading power factor, and reactive power is not a constant power, designing a capacitor bank must consider different reactive power needs. For example, the configuration for a 5-stage capacitor bank with a 170 KVAR maximum reactive power rating could be 1:1:1:1:1, meaning 5*34 KVAR or 1:2:2:4:8 with 1 as 10 KVAR. The …

How does a capacitor in parallel with an inductive load improve power factor? When a capacitor is added in parallel with an inductive load, it creates a capacitive reactance that offsets the inductive reactance of the load. This helps to balance out the reactive power, resulting in a higher power factor and improved efficiency.
Reactive Power. We know that reactive loads such as inductors and capacitors dissipate zero power, yet the fact that they drop voltage and draw current gives the deceptive impression that they actually do dissipate power.. This "phantom …
