14-Bus IEEE Electrical Network Compensated for Optimum Voltage Enhancement using FACTS Technologies

Flexible AC Transmission Systems (FACTS) are important when enhancing an electrical network in stabilising the voltage. The optimal localisation and sizing of the FACTS device depend on the power system and its shortcomings. In this paper, a shunt controlling capacitor for voltage stability was presented. The IEEE 14-Bus trial model was utilised to compare the efficiency of the existing model with and without the shunt compensator. PowerWorld simulator was used for simulation and compensation of the electrical network. Previously, distributed generators (DGs) and other techniques were used to compensate for the original system instead of FACTS devices. Unfortunately, the DG technique was very expensive and created other problems in the power network. There are two scenarios of implementing shunt compensation to the system. Two switched shunt compensators were introduced in the first scenario at the primary (high-voltage) and the secondary (low-voltage) sides. The second scenario had only one switched shunt introduced at a secondary bus. Both scenarios obtained good results concerning the voltage profile being in the correct constraints of 0.95
