For efficient and reliable operation of power system it is important to control voltage and reactive power. In power distribution network, reactive power is the main cause of increasing distribution system loss and various power quality problems. Power quality issues are gaining significant attention due to the increase in the number of sensitive loads. Distribution static compensator is an important device in improving power factor, maintaining constant distribution voltage, and mitigating harmonics in a distribution network. Distributed static compensator is a fast-acting reactive power source that can reduce voltage variations and voltage instability in the power system, and can aid in faster system voltage recovery after contingency events.
