Power Quality Improvement by Optimal Placement of D-STATCOM for Power System Network

This research paper presents a detailed study on the optimal placement of a Distribution Static Compensator (D-STATCOM) in a 14-bus power system. The objective of the study is to identify the optimal location for the D-STATCOM that can compensate the reactive power in the system. The paper proposes a methodology that utilizes load flow analysis and deduction of maximum voltage and current harmonics to identify the optimal location of the D-STATCOM. Newton Raphson method is used for load flow analysis. The load flow analysis is used to determine the voltage and power flow conditions in the system. D-STATCOM control is achieved by direct quadrature zero method. The proposed methodology is validated through extensive simulations on the 14-bus power system. The simulation results demonstrate that the proposed methodology can identify the optimal location for the D-STATCOM that compensates the reactive power in the system. The study provides valuable insights into the optimal placement of D-STATCOM in power systems, which can help power system operators and planners in enhancing the overall system performance and reliability.
