Power plants must have sufficient installed
power capacity to accomplish high demand and must be operated continuously with
sufficient capability to meet real-time demand. Integrating an energy storage
system, such as a battery energy storage system, into a Flexible Alternating
Current Transmission System (FACTS) device can provide the much-needed
flexibility to reduce dynamic decentralized active power capabilities and
transmission-level power flow issues. This
article establishes a control strategy for optimal use of STATCOM and the
Battery energy storage system. The architecture of the BESS, its utility-scale
applications and the benefits of its application in power systems have been
studied, as well as the operation control methods of large-scale STATCOM and
BESS systems have been examined. Application scenarios such as power grid
frequency tuning and power flow optimization are presented. In addition, in the
study where STATCOM and BESS are integrated into the power system, specific
features to support voltage in power grids are demonstrated. STATCOM and BESS
units have been shown to be integrated and improved with optimum power factors.
To reduce energy loss and improve voltage stability, STATCOM has been validated
to simultaneously improve the voltage profile in the interconnected grid by
regulating the active and reactive power in the power transmission line.
Finally, all the comparative results show that STATCOM and BESS devices can
maintain excellent performance in controlling the voltage regulation response
under various faults. The results were considered considering the current
Turkish interconnection system, with a view to identifying potential avenues
for enhancement.
