Power exporting and system stability are some of the major concerns in the transport of electrical energy. It has been acknowledged that FACTS devices are a possible way forward to ensure high throughput of power with enhanced stability. FACTS equipment has lived up-to its promise in cases where system stability has been a concern. BESS application in power transmission is a new area of study which is just commencing to be explored.
The research work assesses the impact of the Static VAR Compensator (SVC) and Static Compensator (STATCOM) on an equivalent Siirtoverkkomalli and Nordic-32. It includes a comparative study of both FACTS devices under unstable network conditions. Preliminary assessments have indicated that, BESS are very effective means for providing frequency and voltage support during load variations. In this work, BESS is applied in Siirtoverkkomalli to assess whether or not BESS can be effective to stabilize an otherwise unstable network.

It has been found that using both the SVC and STATCOM in a transmission system significantly improves stability. The comparison shows that the STATCOM is very effective, outperforming the better known SVC. On the other hand, when a BESS is applied in Siirtoverkkomalli, it shows that it has great potential in stabilizing an otherwise unstable system. Hence, a BESS can perform multiple functions, it provides stability support, similar to the SVC or STATCOM, but it can provide frequency support during load changing periods.
