Low-speed response to shortage of reactive power during certain contingency events is often the cause of voltage collapse in transmission systems. The increase of transmission corridors capacities can be impossible due to the lack of rights-of-way. Oftentimes, the construction of new transmission lines or power generation facilities are not the most efficient and cost-effective solution alternatives. Stability concerns are major problems in power systems especially when transmitting power over long distances. Short-circuit current levels increase significantly in meshed and highly-complex systems. Power quality management and voltage control can be extremely challenging in some networks. These are only few of the problems utility companies are confronted with on a daily basis. These problems can easily be solved by means of innovative solutions, which often involve FACTS devices such as SVC, UPFC, DVAR, TCSC, PST, STATCOM. Additional benefits of FACTS devices include increased transmission capacity, improved grid stability, enhanced network efficiency, reduced environmental impact, and increased damping of oscillations and sub-synchronous resonances.
