Analysis of Back To Back (BTB) Converter Control Strategies in Different Power System Applications

Abstract

Power Quality (PQ) is an important term in many industries and other electrical power consumers. Maintaining of power quality during the operation of industries is an important task as the PQ issues may arise and cause the deviation in normal mode operation. In order to maintain the stability and mitigate the PQ issues, Back to Back (BTB) are mostly used in different power systems majorly in industries. This paper provides a major review on the BTB converters role in different power system configurations which are playing important role in facing the power quality issues such as voltage sags occurred in the system due to any faulty condition or short circuits, harmonic distortions, and some other abnormal conditions. Also in this paper, the various control strategies implemented in the BTB converter at their respective power system configurations are presented which will be helpful in developing the new methods or modifications in using BTB converters for power system applications.

Wind energy conversion technologies and engineering approaches to enhancing wind power generation: A review

“…Moreover, PECs have huge impact on the overall performance of the grid-connected WECS technologies. Among these technologies, the two-level (2L) – current source converter (CSC) [ 15 , 16 ], and voltage source converter (VSC) [ 11 , 17 ] topologies in back-to-back (BTB) configurations were conventionally being employed in small- and medium-scale wind farms for the last several decades; and they were usually compatible with DFIG-based WECS technology. Here, one of the main drawbacks of DFIG-based WECS is that it does not maintain operational compatibility with power converters of increasing power and voltage capacities [ 18 ].…”
