Reactive Power Compensation. A low value of power factor requires large reactive power and this affects the voltage level. Hence in order to compensate for the reactive power, the power factor of the system must be improved. Thus, the methods for reactive power compensation are nothing but the methods by which poor power factors can be improved

Reactive power compensation play an important role in modern era because supplier companies take charges of it, if it exceeds a predetermined value so different companies enforce users to compensate it. In this paper, different topologies are discussed but the appropriate method which we are employing is power capacitor topology. This research
Solution 2 (S2) refers to distributed reactive power compensation with capacitor banks (S2). Table 7 shows the data on the capacitive reactive power of the capacitor bank distributed in the nodes with low PF. In addition, it shows the cost, the apparent short-circuit power, and the harmonics corresponding to the resonance frequency. The

The reactive power compensation helps to increase available maximum load of any transmission line to the thermal limits under stability ranges without complex sizing requirements. This is obtained by using traditional reactive power compensations such as series or shunt capacitors, and variable compensators.

Reactive power compensation systems work by dynamically adjusting the amount of reactive power in an electrical system to optimize performance, enhance power quality, and maintain voltage stability. The working principles vary depending on the type of technology used, but the core aim remains the same: managing reactive power to meet the needs
One way to avoid reactive power charges, is to install power factor correction capacitors. Normally residential customers are charged only for the active power consumed in kilo-watt hours (kWhr) because nearly all residential and single
Reactive power compensation systems work by dynamically adjusting the amount of reactive power in an electrical system to optimize performance, enhance power quality, and maintain
In the past, rotating synchronous condensers and fixed or mechanically switched inductors or capacitors have been used for reactive power compensation. Today, static Var generators employ thyristor-switched capacitors and thyristor-controlled reactors to provide reactive power compensation.
There is a novel method to actively compensate for the reactive current caused by the EMI capacitor. Moreover, the PFC current-loop reference is reshaped at the AC zero-crossing to accommodate for the fact that any reverse current will be blocked by the diode bridge. Both PF and THD are improved as a result. Figure 3.
The proposed method for EMI-capacitor compensation uses this red waveform as its current reference. In theory, if the PFC current loop uses this as its reference, the EMI-capacitor reactive current can be fully compensated, and the PF can be increased. The proposed current reference is further improved as shown in Figure 5.
Reactive power compensation is commonly addressed as a constrained single-objective optimization problem [1-3]. Traditionally, it basically consists in determining an adequate location and size of shunt and/or series capacitor and reactor banks.
If professional advice or other expert assistance is required, the services of a competent professional should be sought. Hofmann, Wolfgang, 1945-[Blindstrom-Kompensation in der Betreibspraxis.

The static VAR compensator (SVC) is the shunt compensation method which is used to compensate the reactive power. The SVC uses Thyristor Controlled Reactor (TCR) /Thyristor Switched Capacitor (TSC) control method by the help of which reactive power is either absorbed or generated. To control the SVC a triggering alpha is used.
