Reactive power compensation is extremely crucial for maintaining the power quality that includes voltage, current, and power system stability [], and it can be ensured using different techniques, including capacitor-banks, synchronous generators, and, likewise, via the flexible alternating current transmission system (FACTS) [5,6].If there is no reactive power …
Switched capacitors are the most common tools used for reactive power compensation. For this purpose, inverter-based static compensators, thyristor-based static compensators and synchronous machines can also be used. Although switched capacitors are cost-effective, it is almost impossible to achieve full reactive power compensation with them.

The reactive power absorbed by a transformer cannot be neglected, and can amount to (about) 5% of the transformer rating when supplying its full load. Compensation can be provided by a bank of capacitors. In transformers, reactive power is absorbed by both shunt (magnetizing) and series (leakage flux) reactances.
With reactive power compensation, transmission efficiency is increased. Along with this, the steady-state and temporary overvoltages can be regulated that resultantly avoids disastrous blackouts. ... As we know that the capacitor takes the leading reactive power, thus this causes the decrease in power taken from the source. This resultantly ...
