Abstract

Integrating Distributed Static Compensators (DSTATCOM) into distribution
networks improves voltage profiles, reduces power losses, and enhances stability.
This paper optimizes DSTATCOM placement and sizing within the 34-bus
Thinkers Corner 6.0 MVA, 33/11KV distribution network in Enugu, Nigeria,
using Particle Swarm Optimization (PSO) in MATLAB R2017b. The Backward-
Forward Sweep method was employed to simulate load flow analysis, both with
and without DSTATCOM, to assess real and reactive power losses, voltage
profiles, and voltage stability indices. Validation of the model was performed using
the IEEE 33-bus system to ensure the robustness of the approach. Results show
that DSTATCOM integration reduces losses, stabilizes voltage, and improves
network efficiency.
