It can be found that the line-current waveform from the source is nearly sinusoidal due to the SMES, although the load line-current contains an amount of harmonic components. 5. Discussions and suggestions SMES systems have found a number of applications to power systems. These applications are demonstrated not only fully by simulations but also partially by experiments. Figure 11 provides an expeditious view of SMES applications to power systems. SMES is the only technology based on superconductivity that is applicable to the electric utilities and is commercially available today. However, because of high cost and large investment of SMES systems, most of the reported studies are implemented through computer simulations or in laboratories. There are only a few cases of practical application. Therefore, with advancements in technologies and reductions in cost of superconductivities and power components, more effort should be launched into practical applications of SMES to power systems. Generally, SMES systems with small capacity are applied to compensate for fluctuating loads, to provide protections of critical loads, to provide back-up power supply, to compensate for asymmetries of currents and voltages from loads, and to R38 Topical Review [11] Ribeiro P F, Arsoy A and Liu Y L 2000 Transmission power quality benefits realized by a SMES-FACTS controller 9th Int.
