| Summary: | This study addressed voltage regulation, power
losses, and efficiency challenges in medium- and low-voltage
distribution networks by implementing a four-stage
enhancement strategy: i) base case evaluation, (ii) network
reconfiguration by adding transmission lines, (iii) integration of
photovoltaic distributed generation (PVDG), and (iv)
installation of capacitor banks for reactive power compensation.
The system was modeled and analyzed in DIgSILENT
PowerFactory. Results showed a 29.4% reduction in active
power losses from 1.7 MW to 1.2 MW and a 39.6% drop in
reactive power losses (5.3 MVar to 3.2 MVar). The active and
reactive power imported from the 132 kV grid decreased by
35.2% and 50.7% respectively, while voltage magnitudes at
substations stabilized at 1.0 p.u. The findings demonstrated that
coordinated deployment of PVDG and capacitor banks,
combined with network reconfiguration, significantly improved
voltage stability, reduced losses, and enhanced system
reliability, thus supporting the shift toward sustainable
distribution networks. |
