The results achieved are as follows: • Without a shunt capacitor, apparent power carried by the line SL = PL + jQL, and power factor cosϕ = PL /SL • With a capacitor, line apparent power, SL1 = PL + j(QL – QC) < SL, and cosϕ1 = PL / SL1 > cosϕ • Ultimately, power losses ∆P and voltage drop ∆V will be reduced after shunt capacitor is installed, i.e. ∆P1 < ∆P, and ∆V1 < ∆V
It is clear that the line active and reactive power flows based on fixed and switched capacitors are lower than those obtained in the case of without capacitors. In addition, the directions of reactive power flows are reversed in nine lines for fixed capacitors and in seven lines for switched capacitors.
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.
There was a notable reduction in active power losses (I2R losses) throughout the distribution lines. The optimized capacitor placement minimized the current flow, thereby reducing resistive losses. Capacitors provided local reactive power support, reducing the amount of reactive power that needed to be transmitted over long distances.
Massoud Danishmal In distribution systems, the generation and transmission of reactive power over long distances are economically impractical. However, this study proposes an efficient solution to meet the demand for reactive power by strategically integrating capacitor banks at load centers.
Current can only flow in a closed loop, so a series capacitor cannot keep reactive current from flowing through the distribution grid, which is the very thing that power factor correction seeks to avoid in order to avoid the resistive losses of that current travelling long distances through practical conductors.

A capacitor bank is a group of several capacitors of the same rating that are connected in series or parallel to store electrical energy in an electric power system.Capacitors are devices that can store electric charge by creating an electric field between two metal plates separated by an insulating material.
