Enhancing power quality through DSTATCOM: a comprehensive review and real-time simulation insights

Power quality (PQ) problems such as voltage sags, swells, harmonics, and transient disturbances pose significant challenges to modern electrical distribution systems. In response, distribution static synchronous compensators (DSTATCOMs) have emerged as effective solutions to mitigate these PQ problems. This paper provides a comprehensive review of DSTATCOM applications in PQ improvement. Beginning with an explanation of the fundamental principle of DSTATCOM operation, it highlights their capability for harmonics, reactive power, and nonlinear load compensation. The review extensively discusses various DSTATCOM topologies and control strategies aimed at enhancing PQ. Additionally, the paper offers valuable insights into the efficacy of DSTATCOMs in enhancing PQ within electrical distribution networks, supported by real-time simulation results.
