Arithmetic Optimization Algorithm for Optimal Installation of DSTATCOM into Distribution System based on Various Voltage Stability Indices

In this article is proposed a new approach based on an Arithmetic optimization Algorithm (AOA) that can notably envisage with diverse problems for optimal installation (locate and size) of Distribution Static Compensator (DSTATCOM) in Electrical Distribution System (EDS). An approach applied for optimal installation of DSTATCOM units in EDS is used as the new multi-objective functions to minimize the Active Power Loss (APL) and various voltage stability indices. The voltage stability indices applied are the Voltage Stability Index (VSI), the Fast Voltage Stability Index (FVSI), the Line Stability Factor (LPQ), and the Power-Voltage Stability Index (PVSI). The methodology is tested on IEEE 33-, and 69-bus EDSs. The results of the simulation confirm that the optimal installation of DSTATCOM plays a significant role in EDS, where excellently reduced the power losses and enhanced the voltage profiles.
